GoBangTetris

GoBangTetris combines GoBang and Tetris. You move falling pieces made of black and white stones sideways and rotate them before they land on the bottom of the playfield or on pieces already placed. You cannot slow or stop their fall, but you can accelerate it.

Clear lines of stones

When five or more stones of the same color line up in a row, column or diagonal, they disappear and the pieces above them fall. Clearing stones earns points, and clearing multiple lines at once can earn bonus points.

Advance through levels

For every 20 blocks that fall, you move up a level. The falling pieces get faster with each level, leaving you less time to decide where to place them.
