The way the pieces click together to form a perfect flat surface is oddly satisfying, and starting with the easier challenges eases you right in. It’s a great way to get some mental exercise during my commute.

I've gone through maybe half the 120 challenges so far, and the way the pieces click into a flat image every time is oddly satisfying. It's a great pick-me-up when I need a few minutes of focus without a screen.

I really enjoy the challenge of turning the 3D pieces into a flat image without any gaps. The 120 puzzles keep me busy, though I wish the pieces didn't slide around quite so much on the board.
