Number Link is a free number puzzle game where you must match pairs of numbers without leaving an empty space on the board.

It sounds and looks simple but it's deceptively tricky although it doesn't require any mathematical skills - it's all about matching. The tricky thing is to avoid the number link lines crossing each other.

There are a daunting 800 levels and several different board sizes ranging from child friendly 5x5 up to absurdly tricky 16x16 making it suitable for all ages.
