Uni B – towers and numbers

In the arcade puzzle game Uni B, building towers of numbers combines with a merge mechanic. Success relies on both strategic planning and perfect timing: decide where to send the next block, wait for the right moment to drop it, and watch as numbers transform into something greater. Three towers stand inside a large white structure. A numbered block moves back and forth above the chosen tower; tap the screen when it is centered to land it successfully. If the block's value matches the one at the top of the stack, they merge—two 2s become a 4, two 4s become an 8, and so on. A merge can trigger a chain reaction by combining with the block below. A tall tower collapses, clearing space and earning bonus points. A next block preview helps you plan your moves and set up future cascades. The game features an endless mode where the goal is to survive as long as possible, create larger numbers, and set a personal best. A single precise drop can transform the entire tower.
