Box Stack: Tower Puzzle

A block puzzle that rewards patience. Plan each drop, finish rows to set a new foundation and keep your tower level as it climbs. Offline, one-handed and never timed

Box Stack is a block stacking puzzle that rewards patience. Plan each drop, finish rows to set a solid foundation, and keep your tower level as it climbs. It plays offline, with one hand, and nothing is ever timed.

A crane holds a crate over a boat in a night dockyard. Slide it sideways, let go, and it falls exactly where you aimed. Stack carelessly and the whole tower goes over the side, boat and all. Keep your balance and it climbs.

A BRAIN GAME FOR PEOPLE WHO THINK AHEAD

Nothing falls until you choose to drop it, so every placement is a decision you get to make properly. Take the easy spot now, or leave room for the row you can finish two crates from now? The players with the tallest towers are the ones who wait for the right move.

HOW THE PUZZLE WORKS

• Drag a crate from the dealer's mat up to the crane, slide it into place and lift your finger to drop it • Blocks never rotate, so the puzzle is about where each block goes, not how you turn it • Fill a row across the tower and it SETS: it stays where it is and becomes the new foundation • Watch the balance gauge. Every crate off centre pulls the tower toward its side, and the higher it sits the harder it pulls • A finished row weighs nothing at all, which is why completing one wins your balance back • Finish rows one after another and the multiplier climbs a step a row, with no ceiling

A NEW TOWER EVERY TIME YOU PLAY

Crates come in waves of three, and each wave is dealt for the board in front of you, so no two games go the same way. As your score climbs the block puzzle gets harder, but every wave still has a way through. Each run deals its own colours, the tower changes colour as it climbs, and some colour sets stay hidden until you earn them.

PLAY ANYWHERE

Box Stack is an offline game, so you need no Wi-Fi for a quick brain game on a plane, on the train or on the sofa. Close it whenever you like: your tower is saved move for move and waiting when you come back.

FAIR ABOUT ADS

One banner sits at the bottom of the screen, below the crates, and that is all. Nothing pops up over the board or between games. Lose a tall tower and the crane offers to catch it: watch an ad and carry on from just before that drop. That is always your choice, once a run.
