A puzzle that
grows on you.

Jigsy looks like a standard piece-fitting jigsaw until you realise that the pieces can also change size. Rotate and scale a piece, and suddenly it fits. That glorious “aha” moment in 3 new grids everyday. Now with leaderboards and streaks.

Play on any device - computer, phone, tablet. A good tablet lets you scale and rotate using natural finger gestures - it's what Jigsy was designed for!

Chapter IThe mechanic

Rotate.
Scale.
Position.

Most geometric puzzles involve figuring out where a piece goes. Jigsy also asks how big it needs to be, and that second question changes nearly everything. Sliding the last piece into place is a powerful moment, every time.
