Shape-packing puzzle. Rotate and drag the pieces to fill an irregular outline exactly, with no gaps or overlaps. Solve as many shapes as you can in 120 seconds.
Each round shows an outline and a tray of polyomino pieces below it. Together the pieces cover the outline exactly — your job is to work out how.
Drag a piece from the tray onto the board. A green preview shows where it will land; release to drop it. Tap the ⟳ button on a piece to rotate it ninety degrees first, since most pieces only fit one way round. Tap any piece you have already placed to send it back to the tray.
A piece can only go on empty cells inside the outline, never on a wall or on top of another piece. When every piece is placed and the shape is completely filled, you score and a new outline appears at once.
Solve as many shapes as you can before the timer runs out.
Start with the most awkward corners of the outline, not the open middle. A cell tucked into a notch or a one-wide spur can only be filled by a piece whose shape ends in exactly that nub, so identifying those forced cells first tells you where specific pieces must go before you waste time elsewhere.
Think about each piece by its silhouette rather than its colour. Before dragging anything, rotate the long thin pieces in your mind and ask which one can reach into the narrowest channel of the shape; the bulky square-ish pieces almost always belong in the open body of the outline, so save them for last and let the spindly pieces claim the tight edges.
Count cells when you feel stuck. The pieces always sum exactly to the outline, so if one region of the shape has, say, five empty cells cut off by what you have placed, only a five-cell piece or a matching pair can fill it. Spotting that a leftover pocket is the wrong size is the fastest way to realise a placement is doomed and needs taking back.
In the timed mode, do not be afraid to pull a piece out the moment it strands an unfillable gap. A quick tap to retrieve it costs far less than forcing the rest and discovering at the very end that nothing fits. Players who keep the outline's holes the same shapes as their remaining pieces solve far faster than those who place greedily from one side.
