Sandpile Panic

Sandpile Panic, also known as Sandpile, is an abstract strategy game based off the abelian sandpile model that involves making piles of pieces. When these piles get too tall, they topple over and cover the area around them. The goal of the game is to cover the board with the largest contiguous area of your color -- and the game ends when a piece topples over the edge of the board.

Sandpile Panic may be played on any grid board with solid-colored stacking objects (such as checkers pieces or building blocks). No specialized pieces are otherwise required. The grid may be as large or as small as desired to affect the length of the game or to accommodate up to 8 players.
