Stack Up

A block slides back and forth above your tower. Tap once to place it. Anything that sticks out is cut away, so the next block gets narrower. Stack carefully, keep your balance, and see how high you can climb. Every 10 successful placements opens a new section with a wider recovery platform so a thin tower can bounce back. Section 1 always enters from the left, section 2 from the right, and from section 3 each block alternates. Speed steps up with every section. HOW TO PLAY • Tap once to drop the moving block onto the tower • Keep the overlap as wide as you can • Nail perfect landings to keep your streak going • Reach the next section for a width recovery and a new pace FEATURES • Endless one-thumb stacking sessions • Sections with recovery platforms every 10 placements • Entry direction and speed that change as you climb • Unlock new color themes as your high score grows • Daily streak: the first blocks of the day start a little slower • Satisfying sounds and optional vibration • Available in English, German, Spanish, French and Portuguese PLAY OFFLINE Stack Up works without an internet connection. No account or login needed — your progress stays on your device. ADS AND REMOVE ADS Stack Up is free to play and contains ads. Banners only appear in the menus and on the game-over screen, never during a round. A full-screen ad can appear between rounds at most after every third game over. Optional reward videos are always your choice: watch one to continue a run once or to unlock a theme early. If you prefer fewer ads, the optional yearly "Remove ads" subscription (€1.99/year) removes the automatic ads (banners and ads between rounds). Optional reward videos stay available whenever you want them. The subscription renews automatically each year and can be cancelled anytime in Google Play. How high can you stack?

Welcome to Stack Up! Stack blocks as high as you can: the more precisely you drop, the taller your tower grows. New sections keep it fresh, watching a video lets you continue with a shield and a wider block, and ad breaks are announced briefly beforehand.
