Material
Each player gets a set of 16 pieces, shown below.
The 16 pieces per player are made of four shapes in four colours (yellow, cyan, green and red). Each colour has one piece of each shape, so each player has four pieces of each colour.
How to Play
The game is played in a virtual grid according to the constraints, until one player cannot play. The last player to place a piece wins.
Constraints
-
Connected: after the first piece, each piece you play must touch at least one other piece orthogonally.
- Correct: a cyan piece and a red piece placed side by side, touching along an edge.
- Incorrect: a cyan piece and a red piece that touch only at a corner.
-
Different move: you may not play the same type or colour that your opponent just played.
-
Not adjacent: you may not place a piece adjacent to a piece of the same type or colour.
- Incorrect (same shape): two pieces of the same shape placed next to each other.
- Incorrect (same colour): two cyan pieces placed next to each other.
-
Virtual grid: you may not play so that the playing area exceeds 9 squares in any direction.
Example
Player A (bottom) has just played a small blue square (X). Player B (top) loses, as she can't make a legal move.
The example diagram shows the playing area after Player A's move, with the remaining pieces of each player shown above (Player B) and below (Player A). The small cyan square marked X is the piece just played.
For Your First Games
Play only with the pieces sized 1-3; the playing area may not exceed 7 squares.
