Object: Determine the order of the serviettes. (2 variants)
 
Eight square sheets of paper, all the same size, have been placed on the table. They overlap as shown.
One sheet (1) is shown completely, and the seven others are only partially exposed. Click the squares to number them in order from top to the bottom.
 
It is easy to create puzzles of this type, but you must be careful not to devise one that allows for more than one answer.
 
 
For literature on these and similar classic puzzles see:
- many books by Martin Gardner
- many books by Kobon Fujimura, for example: 'The Tokyo Puzzles' 1979.
