Hoistwell

A harbour crane swings a block over the pier. Drop it at the right moment, stack it on the tower and reach the target height before you run out of blocks.

Every block has a shape and a weight. After each drop the game checks the combined centre of mass above every edge in the tower, so an overhang that looks fine can tip the whole stack two floors below.

• 12 building sites, each with a target height, a fixed sequence of blocks and up to three stars
• Eleven block shapes in five materials: concrete, timber, steel, glass and stone, from light glass boxes to heavy ashlar
• Real balance check: a block that hangs too far slips into the sea and costs one block; a leaning tower topples and costs the site
• Wind from site 4 pushes the swing and the falling block; the trolley travels along the jib from site 5, and from site 7 the wind turns in gusts
• Perfect drops build a combo multiplier; spare blocks pay a bonus
• One button: Space, the Down arrow or a tap drops the block
