Tap to drop. The block above slides back and forth — let go at the wrong moment and the overhang shears away, and your tower gets narrower. Land it dead centre and you get that width back. That is the whole game. It takes five seconds to understand and a long time to be good at. THREE MODES NORMAL — just the tower. Every miss costs you width, every perfect drop hands some back, and the block speeds up the higher you climb. Sooner or later it outruns you. ARCADE — pickups hang out to the sides. Swing a block wide to catch a Widen, a Slow, a double-points streak. Reaching one costs you width, so every pickup is a decision rather than a gift. Some of them bite: Overdrive triples your score and makes the block fly, Flipped turns the screen upside down. And a few you steer around entirely. GRAVITY — nothing is trimmed. Every block lands whole, in whatever width you are dealt, and the tower leans according to where the weight sits. Stack too much to one side and it goes over. A narrow block placed off-centre is a counterweight; a wide one is ballast you have to think about. WHAT IS IN IT - One tap. No buttons, no menus to learn. - Plays offline, on a plane, anywhere. - No account, no sign-up — just open it and play. - A separate high score for each mode. - Its own sound for every drop, trim, and perfect landing — or play it silent, your call. - Colorblind-friendly colors, VoiceOver, and Reduce Motion support. - Share your run as a card that draws the tower you actually built. - Optional one-off purchase removes the ads for good. Built for iPhone and iPad.
