About

Cube 27

Features
Read full description

Cube 27 takes the number-merging puzzle into three dimensions. The board is no longer a square — it is a cube of 27 cells. You can push the tiles in six directions: up, down, and the four sides. Matching numbers merge on contact. What matters is not the single merge but the thread between them: keep merging every move and your chain grows, pushing the multiplier up. Waste one move and the chain snaps back to zero. That is where the tension lives. HOW TO PLAY • Swipe anywhere: the tiles push that way. A vertical swipe means up/down, diagonals push the side axes. • To see inside, double-tap or pinch open — the layers separate, and you can keep playing while they are apart. • Use the rotate buttons to turn the cube and see the far faces. • The tutorial in the menu walks you through all four mechanics on the real cube. FEATURES • Daily Cube: everyone plays the same layout each day, with a single attempt. Days you miss can still be played as practice. • Combos and chains: land three or more merges in a single move and the instant multiplier kicks in; every uninterrupted merging move raises your chain one step. The two multiply, capped at x9. As the chain climbs, so does the melody — you can hear where you are. • Rising tempo: as the cube fills, the pace increases and moves start bringing two tiles. The counter is on screen, so the pressure is never a surprise. • Your unfinished game is kept — close the app and come back where you left off. • Sound and vibration can be switched off in settings at any time. • English and Turkish. FULLY OFFLINE No internet needed to play. No ads, no purchases, no account. Leaderboards are optional and only send the nickname and score you choose. Can you build the 2048 tile before the cube fills up?

Verdict
