Get your cups in a row. Swallow theirs to get there. And be careful what you lift: whatever was hiding underneath is back in the game.
Computer level: Normal
Classic only: your pieces start in three nested stacks, so the big ones come out first. A new piece must go on an empty square; the one exception is that it may gobble a piece in a line where your opponent already shows three.
Field Goal (Touchdown and Bridge, 5×5): no rows to make. Coral heads for the top edge, blue for the bottom. A new cup can only enter on your own home row. A cup on the board moves one square in any direction and must land next to another of your cups, so you cross the board as a chain. Bigger still swallows smaller, and a swallowed cup is nobody's. Touchdown: get any one cup onto the far row. Bridge: make an unbroken chain of your cups from your home row to the far row. A player with no legal move loses.
Chaos 5×5: five sizes of cup, fifteen each. Four in a row anywhere on the board wins, and a new cup can gobble straight from your hand.
The same position three times is a draw. Drag to look around the board, scroll to zoom.
