The IQ Jigsaw Puzzle

The pieces have a satisfying, chunky feel, and the way they interlock is really clever. I've already worked through a dozen of the 120 challenges, and each one feels like a fresh brain teaser.

The 120 challenge levels keep this on my coffee table every single night. I love how the jigsaw-shaped pieces force you to think completely differently than a standard puzzle, and even the easier setups take a satisfying few minutes to crack.

I've already cycled through maybe thirty of the 120 challenges and the variable difficulty keeps it fresh every time. The way the jigsaw-shaped pieces interlock into the 6x6 grid is far more satisfying than I expected, especially when a seemingly impossible setup finally clicks into place.
