Two teams of worms take turns. On your turn walk, jump, aim and fire one weapon before the time runs out — then run for cover! A worm that falls into the water is gone. The last team standing wins.

Hold Fire longer to shoot further. The wind at the top carries bazooka shots and air strikes. Grenades bounce and go off when their fuse runs out (1–5 seconds). The dotted line shows where your last shot flew.

Crates fall from the sky: health, weapons and tools like the jetpack, the teleport, double damage and low gravity. Oil barrels and mines blow up. In sudden death the water rises after every turn.

Phone and tablet: the game goes fullscreen. A joystick appears where you touch the left half: sideways to walk, up and down to aim. Hold Fire at the bottom right to shoot; Jump and Back flip are above it. Tap the map to pick a target, drag it to look around, pinch to zoom.
