Tower Smash is a casual, maze-tower puzzle game with physics elements similar to Helix Jump, Jump Tower 3D and Neon Tower. A ball that leaves paint behind on surfaces bounces repeatedly in place on the top level of a tower. The structures has a cylindrical central column and rounded platform layers sticking out of it in a twisted rope pattern. The tower and platforms rotate automatically. The player must direct the ball's movement down through colored platforms without hitting any of black ones.
If the ball hits one of the black platforms, it shatters into shards like ceramic. The game also makes a broken dish background sound. Otherwise, the ball continues downward, and the colored and black platform layers drop away from the center cylinder. Unlike similar helix-maze games, the ball doesn't break if it drops automatically onto a black platform after the player stops manually directing it on the previous level.
Tower Smash offers interesting twists to this category of games. The ball's bounce speed changes at different intervals. The tower's entire rotation, or only the rotation of some layers, can switch at any time. If the player doesn't manually direct the ball through levels within a specific number of seconds, a red stopwatch activates. If time runs out, every platform on all levels turns black, and the ball loses its color and breaks.
