This app strengthens students visual-spatial skills. It’s more like a puzzle than a game. The concept is deceptively simple – connect pairs of numbers (by creating a path) without leaving any empty spaces on the game board and without crossing over an existing path. The board starts out with 5 rows of 5 and gradually increases in complexity to a 16 x 16 board.
It connects to Apple’s Game Center, but you do not have to choose this option to play. There is a free version, but of course it comes with ads. In-app purchases provide more hints and open up new levels.
