Foil is a board game primarily for two opponents. However, the board design allows configurations for more players.
Each player has a source node from which his/her pieces originate. The object of the game is to remove the opponent's piece on his/her source node.
Each piece is a six-sided dice, where each face represents a state. A turn consists of a player using a piece to "act" and then be removed from the board. Depending on the state, the piece can act on:
a) An empty node
b) One of his/her own pieces
c) One of the opponent's pieces
The remaining player's pieces then sequentially back-fill the empty node until the source node is left uncovered. The player can then add a piece of any state to the source node.
There is one exception: the Thrust! In a "Thrust", a player moves a piece from one node to another. The backfill process on proceeds to the baseline, whereby an empty node is left. In an "Thrust" move, the source node is left unchanged.
The "states" of the pieces are as follows:
1) Neutral
2) Create - adds a peice of Neutral State to the board
3) Change - changes the state of any of the players pieces to another state
4) Recruit - changes opponent's pieces of State 4 or less to players own piece of Neutral State
5) Eject - removes opponents piece of State 5 or less
6) Block - acts as barrier to other states. Can sacrifice itself to remove other adjoacent opponent's piece of State 6
