What the app does
- 120 levels in three modes: Grid (from 3×4 to 8×8, up to 12 pieces), Shapes (animal and object silhouettes) and Expert (large silhouettes and mosaics).
- Five tiers of rising difficulty: Discovery, Easy, Medium, Hard, Master.
- At first the pieces come the right way round; later you have to turn them, then flip them too.
- A level opens once the previous one is solved (a button unlocks every level).
- Drag and drop the pieces with a finger or the mouse; Turn, Flip, Undo and Restart buttons.
- Three hints per level: each puts one piece in its true place. The solution is offered only after 45 seconds or when no hint is left.
- Timer, move counter and up to three stars depending on the hints used.
- Progress is kept on the device.
