Smart Games IQ Deluxe - IQ Pentagon

A brain game for smart teenagers and equally smart adults.  By Smart Games, this is rated 'Advanced' difficulty rating (4 out of 5) and getting to the end of the challenge booklet will probably be beyond 99.9% of the population, myself included.

120 challenges which start out 'easy' and get harder and harder.

The booklet will tell you where to put several of the 11 gem pieces and then you have to work out where to place the remaining ones. If you're tempted to cheat, the solutions are in the back.

Age suitability: 14 years upwards to intelligent adults.
