Daniel ★★★★★

The laser-cut wooden cards have a satisfying weight and feel that makes the trick seem more polished than I expected. My niece was genuinely baffled when I guessed her number correctly three times in a row. It’s simple enough to learn in a few minutes but still feels like real magic.

Matthew ★★★★★

Picked these up for a family game night and the laser-cut wooden cards have a really satisfying weight to them. The math trick is simple enough for my 10-year-old to follow but still fooled everyone at the table. We've already run through it a half-dozen times and the surprise hasn't worn off.
