A heart on one side, a rectangle on the other, and no easy way in.

The board is double-sided — heart-shaped on top, rectangular underneath — so you're really getting two different puzzles in one box. Place the pieces the challenge specifies, then fit the remaining ten double-sided pieces so every groove lines up with the grid.

120 challenges, ages 7 through adult, and the double-sided pieces mean the number of wrong answers available to you is considerably larger than it looks.

Perfect for: solo puzzlers, travel, Valentine's gifting that isn't chocolate, and anyone who thinks they're good at this sort of thing.
