Smart Games IQ Deluxe - IQ Square

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. If you're tempted to cheat, the solutions are in the back of the book.

The booklet will tell you where to put several of the 12 odd-shaped pieces and then you have to work out where to place the remaining ones.

Age suitability: 14 years upwards to intelligent adults.
