Y-E-S is the easy part! Rearrange all three individually symmetrical metal letters until you have a single symmetrical shape. There’s only one solution though – and you may be saying "no” after a few attempts before you successfully say "Yes!”

Designed by Puzzlemaster Vladimir Krasnoukhov, an inventor who uses mathematics and psychology to create puzzles that look like magic. Every solution requires ‘out of the box’ thinking, always with unexpected results. This is why Krasnoukhov’s puzzles are considered effective "brain exercise”.
