Tumblesky: a block-rolling puzzle for your browser

Tumblesky is a free puzzle game about rolling a block across floating sky islands. Each move tips the block over one of its edges, so every level is a small plan: work out how to arrive, then stand the block upright on the socket.

How to play

• Arrow keys roll the block one tumble at a time.
• Stand the block upright on the socket to finish the level. The socket only takes the block in one exact pose.
• Z undoes a move, Y redoes it, and R restarts the level.
• Esc opens the menu. Enter confirms, and the mouse works too.

50 free levels in five skies

Each sky brings a new block and new tricks, from glass that breaks under a standing block to wind vents, portals and blocks that split in two. Nothing moves until you press a key, and a mistake costs nothing because undo is unlimited. Your progress is saved in this browser.
