Hingewise

How to play

• Lift and place. Tap a screw to lift it, then tap a hole to put it in. A lifted screw keeps holding its boards until it goes into a new hole.
• Mind the layers. A hole takes a screw only if nothing covers it, unless a board's own hole lines up there, which pins that board.
• Real physics. Freed boards swing, collide with boards on the same layer and knock against every screw that isn't pinning them.
• Undo and restart. Each attempt gets one free undo. Restart is always free and gives the free undo back.
• The drill. Spend points to drill an extra hole, but every level is solvable without it.
