Duel Stack: Multiplayer

Stack blocks, freeze opponents, climb the ranks! New 3D visuals, smarter opponents, and smoother gameplay. How high can you stack?

Stack blocks. Challenge players. Climb the ranks.

Duel Stack is a fast-paced 1v1 block stacking game. Two players stack blocks at the same time on a split screen — land your blocks precisely or watch them shrink. Miss completely and you lose.
