Cube Tower Stack

Stack colorful 3D pieces, master the balance and reach the top. A free physics puzzle with local high scores, offline play and no ads.

Stack. Balance. Reach the top!

Cube Tower Stack is a colorful 3D physics puzzle for iPhone and iPad. Rotate each piece, choose its landing spot and let gravity decide what happens next. Every drop can strengthen your tower—or send it tumbling.

BUILD SMARTER Fit as many pieces as you can below the height limit. A dense, stable tower earns more points. Make precise landings, build combos up to ×5 and chase three-star results.

TAKE CONTROL • Discover 19 flat and 3D piece shapes. • Rotate pieces freely in three axes. • Use the landing guide to plan your next move. • Orbit, tilt and zoom the camera with two-finger gestures. • Choose the optional drop button to place pieces at your own pace.

ONE MORE TRY Watch the tower sway, survive close calls and work through four building phases. Reach the top for a colorful celebration, then try to beat your best score. Save an optional player name in the top-20 leaderboard on your device.

PLAY YOUR WAY • Free, with no ads or in-app purchases. • No account or internet connection required to play. • Local scores and settings stay on your device. • Music, sound effects, haptics and reduced-motion settings. • English, Brazilian Portuguese, Spanish and French. • Designed for portrait play on iPhone and iPad.
