Ouroboros

Ouroboros is an abstract strategy game for 2-4 players, best with 2 players. Players start with no discs, and gain discs from other players during gameplay.

Ouroboros is played on a 6x6 grid filled with four-colors of randomly placed discs. On each player's turn, they do one of three things:
1) Choose a square with a disc in it to place a stone there, taking the disc from that square and giving away the discs orthogonally or diagonally adjacent, OR
2) Remove two stones from the board matching a pattern and discard many discs in specific amounts, OR
3) Discard one disc.

The winner is the first person to get back to zero discs (after the first turn).
