ROCKS

In ROCKS, a two-player strategy game, you and your opponent try to trap one another in a cave that gets smaller every turn.

To setup, each player gets three random cards and three more are placed in a common area ("the wall"). Players position their pawns on the grid and each add a rock.

On your turn, first play one of your cards, doing its action and then exchanging it with one of the cards from the wall. Next, move your pawn one space. Finally, add a new rock adjacent to your pawn.

At the end of your turn, if you've been trapped (totally surrounded), your opponent wins the game.
