Attactics
based on the game of Ataxx (http://www.pressibus.org/ataxx/indexgb.html)
A game using Icehouse pieces and a chessboard by G. Nick D'Andrea and Sniffnoy
For 2 to 4 players, one stash per player

To Start:
Each player places 1 small of their color in a corner of the board.

On your turn:
You must do one of the following with one of your pieces -
(1) Move/clone a piece
(2) Grow a piece
(3) Shrink a piece

Moving/Cloning:
A piece may move up to two spaces in any two separate directions, diagonals included. If a piece is moved to an adjacent
square (including diagonals), then it is cloned instead of moved. Or, in diagram form,
+-+-+-+-+-+
|M|M|M|M|M|
+-+-+-+-+-+
|M|C|C|C|M|
+-+-+-+-+-+
|M|C|X|C|M|
+-+-+-+-+-+
|M|C|C|C|M|
+-+-+-+-+-+
|M|M|M|M|M|
+-+-+-+-+-+
Where 'X' is the piece, 'C' is where it can clone to, and 'M' is where it can move to.
When a piece is cloned, the new piece is of the same size, or if none are available, then the smallest available piece
that is at least as big may be used. If there are none, the play is illegal.

Capturing:
When a move/clone places a piece next to enemy pieces of the same size or smaller, those enemy pieces are replaced by your
own pieces of the same size from your stash. If none are available, you must move your pieces (other than what you have
just moved/cloned or taken) to replace the pieces you have just captured. In the rare instance where you run out of pieces
from your stash and the board, use the smallest larger piece from your stash. If none are
available, destroy the captured piece.

Note: All captured/destroyed pieces are returned to their owner's stashes.

Growing:
A piece can be replaced by a piece of one size larger from your stash. If none are available, the play is illegal. All
adjacent pieces, regardless of color, are reduced by one size if possible (Smalls are destroyed).

Shrinking:
A piece can be replaced by a piece of one size smaller from your stash. If none are available, the play is illegal.
Exception: You may return a small to your stash, with no replacement, for the same effect. All adjacent enemy pieces are
captured as stated as above, regardless of size, and all adjacent friendly pieces are destroyed.

If at any time you have no pieces, you are eliminated.

You win if at any time all of your pieces are on the board or if you are the only player with pieces on the board.

For two to eight players, using one stackable Icehouse stash per player. Also, three ordinary dice and one deck of Aquarius cards (another Looney Labs game) are needed. Only the 40 Element cards from the Aquarius deck will be used. Overview Each player starts out with a world of their own, and three colonists on it. Players grow the civilization on their world, eventually developing spaceports and ships to expand to other worlds. (Sometimes this means fights over the same real estate.) The object of play is to develop an interplanetary empire which is widespread, supported by a fleet of ships, and rich in all five classic elements: air, earth, fire, water, and ether. Glossary Pyramids on a world: Upright pyramids are colonists. Three-pip colonists are also known as spaceports. Sideways pyramids are invaders. Pyramids off-world: Upright pyramids are transports. Pyramids stacked on transports are marines. Sideways pyramids are fighters. Both transports and fighters are also called ships. Worlds (built with Aquarius cards): A territory is one printed zone of an element on one card. Cards may have one, two, or four territories. There are five elements: air, earth, ether, fire, and water. A region consists of two or more territories of the same element, which touch each other along edges. (A lone territory with no neighbor of the same element is also a region.) A tile is one-fourth of a card. Each territory can be one, two, or four tiles in size. Territories are adjacent if they touch each other at either an edge or a point. Note that adjacent territories of the same element are not necessarily in the same region, unless they touch along an edge. Off-world zones (used only by ships): Each world has an orbit, represented by a face-down card next to the world. Space is a single infinite zone, adjacent to all orbits. Setup Deal out the 40 cards into eight face-down piles of five cards each. Each player receives one pile. Unless eight are playing, one pile will be designated as a neutral pile. Extra piles are set aside, out of play. Players each build a world, using their pile of five cards and the World-Building rules which follow. A neutral world is also built from the neutral pile, by consensus. If no consensus can be reached concerning two or more legal card placements for the neutral world, decide by lot. Each player then places a colonist on each of three territories of their world. The youngest player will then take the first turn. Other players take turns in order of increasing age. World-Building Turn over the first card of the pile. Turn over each of the next three cards, one at a time, and place it next to the card(s) already in this world. Cards must be positioned long edge to long edge, or short edge to short edge. The third and fourth cards must be placed in relation to the first two to form a 2 card by 2 card rectangle. If it is possible to place the card so that an element on it forms a region with a territory already on the board, the card must be so placed. The fifth card remains face down. Put it next to the world to represent that world's orbit space. If this world belongs to a player, and it is impossible to build a spaceport on it (no territory is adjacent to four or more others), turn the orbit card face up, and replace one card now in the world with the orbit card, following the usual rules. (The replaced card is turned face-down as the new orbit card.) If the world is still not playable, the player must take one of the extra piles to build a different world, and set these cards aside out of play. Should no extra piles be available for this, gather up all cards and re-deal. The Turn Cycle There are four parts to each player's turn: Expansion, Survival, Movement, and Fleet Battle. Expansion Take one action on each world where the current player has pyramids. The two possible actions are Expand (place a pyramid) or Civilize (change a pyramid's size). Expand: Place any size pyramid available in the stash upright in any unoccupied territory on the world. Be warned that while it is legal to expand in any open territory, the new pyramid may not survive in a given location. However, it will survive long enough to have an effect. In other words, sacrifices are allowed. Civilize: Replace a pyramid of the current player with a pyramid from their stash one size bigger or smaller. If the desired size is not available, the civilize action is not possible. A pyramid may not change size from one pip to three, or vice versa, in one action. Survival Check each world where the current player has pyramids, to see what pyramids survive. All pyramids on the world are checked, regardless of ownership. Colonists survive or die based on how much support or pressure they get from their neighbors. Small pyramids need at least two neighbor pyramids, but can't stand more than three. Medium pyramids need at least three neighbors, but can't stand more than four. Large pyramids need at least four neighbors, but can't stand more than five. The size, color, and status (colonist/invader) of the neighbors do not matter. Neighbors include all adjacent territories, both at edges and at points. Knock over all unhappy colonists. Leave them in their territories as they are dying, not yet dead. (They don't become invaders; knocking them over is a convenience for checking.) They count as present while evaluating their neighbors on this round. Do not remove dying colonists until all pyramids on the world have been evaluated. After a pyramid dies and is removed, their former neighbors may be left with too few neighbors, but they will not die before the next Survival check on this world. Invaders survive or die based on off-world support. An invader survives if a transport of its color, large enough to transport that invader, is in orbit to support it. If a player has two or more pyramids on the world, they are no longer invaders. Turn any sideways pyramids upright and check them for Survival as colonists instead. Once every pyramid on a world is checked, remove all dying pyramids simultaneously. Remember that only worlds where the current player has pyramids are checked! Last Round: If the current player has 13 or more pyramids in play after all Survival checks, the Last Round begins. Finish the turn. Each player, including the current player, then gets one more turn, after which the game ends. Movement The current player may move all, some, or none of their pyramids in the following strict order. Each one- or two-pip colonist may migrate to an adjacent empty territory. Each spaceport (three-pip colonist) may perform one launch or return. A launch moves a colonist from a territory to that world's orbit. The colonist may become a transport or fighter, or may become a marine by boarding an empty transport of the same size or larger. A return moves a ship or marine from orbit to an empty territory on that world's surface to become a colonist. Each fighter or transport in orbit and not carrying a marine may change its status. Fighters may turn upright to become transports; transports may lie down and become fighters. Each transport in orbit carrying a marine may land that marine, placing it into any empty territory on that world. The marine becomes an invader or colonist, according to the type of the current player's other pyramids on the world. If the world now has two or more invaders of that color, all turn up and become colonists. Each invader may move from a world's surface to board an empty transport of its color in orbit. The invader becomes a marine. A transport may only hold one marine, which must be of the same size or less. Each transport or fighter may move from any orbit to Space, or from Space to any orbit. Any number of ships of any colors may occupy Space or any orbit. Fleet Battle In any orbit where the current player and one or more other players have ships, fleet battle takes place. (Fleet battles never take place in Space, which is too vast.) The current player determines the order in which the various worlds have their battles. At each fleet battle site, the following steps take place. The owner of the world may fire each of their ships once, at a ship of another color. (If this is the neutral world, there is no owner.) The owners of the ships just fired upon may fire each of their ships once (not just the ships that were attacked) at a ship of the world's owner. The current player, if not the world's owner, may fire each of their ships once, at a ship of another color. The owners of the ships just fired upon may fire each of their ships once (not just the ships that were attacked) at a ship of the current player. Any other player with a spaceport on the world and ships in that orbit may fire each of their ships once, at a ship of another color. (If there are two or more such players, each takes a turn in ordinary turn order counting from the current player.) The owners of the ships just fired upon may fire each of their ships once (not just the ships that were attacked) at a ship of the attacker. No ship or player is ever required to fire. To fire a ship, name a target for the ship, and roll a number of dice equal to the firing ship's pip-count. A transport may not be a target if that player also has a fighter present. A transport scores a hit for each 6 rolled. A fighter shooting at a fighter scores a hit for each 5 or 6 rolled. A fighter shooting at a transport scores a hit for each 4, 5, or 6 rolled. Hit ships immediately roll defensive dice equal to their pip-count. Each 6 rolled cancels one hit. Any hits not cancelled reduce the size of the hit ship by one size per hit. If the proper size pyramid is not available in the player's stash, reduce the hit ship by another size. A ship reduced below one pip is destroyed. A transport which is reduced to the point where it is too small to carry any marine now on it also removes the marine. After each world's battle is resolved, take up another world until all battles are resolved. When all fleet battles are finished, it becomes the next player's turn. Scoring After the Last Round has ended, each player receives six scores: Air, Earth, Fire, Water, Ether, and Progress. Each element score is the score of the highest-scoring region of that element occupied by the player. If the player occupies no territories of an element, that element score is 0.5. The Progress score is 1 point per ship, plus 3 points per world on which the player has pyramids. A region's score equals the pip-count of your largest pyramid in that region, multiplied by the number of tiles in the region. Two or more players may score for the same region, and these scores may differ. Multiply the highest element score, the lowest element score, and the Progress score together. Add the other three scores to this product to get a player's final total. The player with the most points wins. Version 1.1 Designed by Glenn Overby Expansion and Survival mechanics modified from "http://www.boticelli.com/boticelli/looneylabs/gameice/protozoa.html"> Protozoa by Kerin Scheisser Aquarius designed by Andy Looney Playtesters still wanted! The major issues right now are: 1) The interaction between colonists and invaders. 2) The die rolls in space combat (Too bloody? Not bloody enough?). 3) The timing for the start of the Last Round.

Martian Greenhouse a solitaire Icehouse game by Becca Stallings

Number of Players One. Number of Stashes Any even number, preferably four or six. Opaque colors make a more challenging game. Premise You are a botanist hired to genetically engineer Martian flowers for colonists to plant in their gardens. Your employer gives productivity bonuses, so you want to produce each flower with the fewest possible generations of breeding. The genetic structure of the Martian flower consists of six pyramidal chromosomes arranged in a linear configuration or «stack». When flowers breed, they produce two offspring, with three chromosomes from each parent going into each child. The three chromosomes from one parent always remain in the same order relative to one another. Setup Before beginning the game, write a list of the flowers ordered by your employer and set it aside for reference. (The longer the list, the longer your game. Make sure your list does not require more than five of any one kind of pyramid.) Next, collect some breeding stock from the wild and set up your greenhouse: Put all the pyramids into a bag, draw them out without looking, and form stacks of six. Line them up on the table, leaving some laboratory space between you and the greenhouse. Playing Select two flowers to breed. Take them from the greenhouse into the lab. Unstack each flower, being careful to keep the chromosomes in order, so that you have two parallel rows of six. Decide which three chromosomes from one parent will combine with which three from the other parent, and slide those pyramids into the area between the rows, keeping them in order. Next, decide how the three from one parent will mesh with the three from the other. Chromosomes from the same parent have to stay in order relative to each other, but they can intersperse in any way with those from the other parent. That is, if one parent contributes one of each size red (1R, 2R, 3R) and the other parent contributes one of each size blue (1B, 2B, 3B), the offspring's genetic structure might be: 1R, 2R, 3R, 1B, 2B, 3B 1R, 1B, 2R, 3R, 2B, 3B 1B, 1R, 2B, 2R, 3B, 3R 1B, 2B, 1R, 2R, 3R, 3B; etc. Stack the chromosomes to produce one offspring. Then stack the remaining six chromosomes, using the same rules, to produce another offspring. When breeding is complete, you may choose to place both new flowers in the greenhouse and select two different ones to breed, or you may keep one new flower and breed it with any flower from the greenhouse. You may not breed the two new flowers with each other, as such incest will cause deadly mutations. Continue breeding until you have produced all the flowers on your list. Example of Play Suppose one of the flowers on your list is pure purple, with two smalls on top of two mediums on top of two larges. 1P, 1P, 2P, 2P, 3P, 3P From the greenhouse, you choose a pair of flowers which together happen to contain one of each size of purple, Flower 1: 2B, 3R, 1B, 1B, 2P, 3R Flower 2: 2C, 1P, 1C, 1R, 2B, 3P and select the purple chromosomes plus enough extras to make a flower, From No. 1: 1B, 2P, 3R From No. 2: 1P, 2B, 3P and stack them together into a half-purple offspring. 1P, 1B, 2P, 2B, 3P, 3R The remaining chromosomes are From No. 1: 2B, 3R, 1B From No. 2: 2C, 1C, 1R and you stack them to make the other offspring. 2B, 2C, 1C, 1R, 3R, 1B For your next turn, you put the non-purple offspring back into the greenhouse and breed the half-purple offspring with another flower from the greenhouse, which happens to contain at least one of each size purple, 1P, 1B, 2P, 2B, 3P, 3R (your offspring) 3P, 1P, 2P, 2P, 3R, 3P (greenhouse flower) and you set aside one of each size in the needed order from each parent, From your offspring: 1P, 2P, 3P From the other one: 1P, 2P, 3P which you then combine to fill the order. 1P, 1P, 2P, 2P, 3P, 3P (congratulations!) If more flowers remain, play would continue by combining the remaining six chromosomes from your success into a new flower, and then either pairing it with something in the greenhouse or bringing out two greenhouse flowers. Comments by the Editor Becca posted this to the Icehouse mailing list in June of 2002, and it disappeared from sight shortly thereafter. I stumbled across the old email a few months later, and thought it worth preserving on the Web. Becca gave permission, so here it is. Like most solitaires, it's more of a puzzle rather than a game. But a nice feature is that the same order list can be played several times, since the starting group of flowers is randomized. This ranks up with solitaire Volcano (and practicing Thin Ice or CrackeD Ice) as the best one-player Icehouse diversions. This plays well using three to five orders with four stashes, or five to seven orders with six stashes. And yes, using black or white (or both) greatly increases the challenge.
