Technicolour Optillusion Puzzles - Set of 4
These optical illusion puzzles might only have 16 pieces, yet they are amazingly difficult to solve! Each puzzle has tiles that change from one image to another as you rotate them. Kaleidoscopes that flip... squares that twist... spirals that spin!
Each puzzle comes in an individual tin. Each puzzle is 11 x 11 cm, and the individual pieces, which are magnetic, stick to the tin base, which is 14 x 14 cm. You can use the tin to store the pieces, when not in use.
