A crane swings your next block above a wobbly tower. Tap at the right moment to drop it. Stack high enough and the little climber on your tower grabs the crate hanging above him. Every run has a goal: a crate, hanging just out of reach. Every crate has a part of something inside. Open all eight to find out what they build. - One tap: the only thing you choose is the moment - 16 crates in two chapters, and a surprise when each chapter's last one opens - Three missions always running, with progress on every run, even the ones that fall over - Party hats, specs and a moustache for your blocks, earned by playing - 19 sky sightings to spot as your tower gets taller - Plays offline, with no account and no sign-in THE MISTAKES GET HEAVIER The game never gets harder. The crane swings at the same speed on your first block and your fiftieth. Your tower just gets taller, and everything you rushed at the bottom starts to matter. Gravity keeps honest books. EVERY BLOCK IS SOMEBODY Every block is a small character with a face and a temperament. They squint, they fret, they sweat as the tower sways. Land something heavy on one and it strains. Push your luck and they go from calm to worried to outright panic. The one that finally falls gets spiral eyes on the way down. EIGHT CRATES, ONE SECRET Every crate holds one part, and nothing tells you what the parts are for. The first crate hangs at 2.5 m, the eighth at 16 m. Some bring a new block or tool with them: a wide deck to steady a wobble, a preview of the next block. Open all eight and the parts come together. Chapter two is for serious stackers: eight more crates up to 26 m, some with a block budget, some hanging off to the side. After that, the stars. MISSIONS AND HATS Three small missions are always on the go: land a block dead centre, stack a block on its twin, help the climber up a few more pegs. They count across runs, so a tower that topples still gets you somewhere. Finish a set and your blocks get something new to wear, from a party hat to a crown. SOMEBODY IS UP THERE Stack past the clouds and the sky starts noticing. A little guy on a cloud, eating mustard. A watcher who waves back, a bit more of him each time you reach him. A moon that wakes up and stares. A whale. A door, ajar, that never opens. Every one you spot is counted, and some of them are rare. Tap to drop. Help him up. Then watch it all come down.
