Hints
Solution
Incorrect
Too bad!
Have you tried counting all the triangles?
Correct
Excellent!
- US Version
Was it tough to assemble in your head? There's actually a really easy way to solve this puzzle. Did you figure it out?
The frame is composed of 22 identical equilateral triangles. The six blocks together are composed of 24 triangles, which is two too many. This means the unused block must be the one made from only two triangles!
