Grids

So you think you can add? Grids is an exciting, fun-filled game that exercises
some of those basic math skills. But it is not all serious work and you can
still enjoy the game without bothering with the math. A great game for players
of all ages, especially useful to get kids excited about math.

16 numbered tiles are organized in a grid. Adjacent tiles are swiped together
to earn points equal to the sum of the 2 tiles (plus some variations). The
objective of the game is to maximize your points and add some sizzle to that
high score table! Multiple levels are available, with each level adding some
twist to the game. Basic levels can be played for free; advanced levels can
be unlocked with an in-app purchase.

This game works great on all screen sizes, whether a 4-inch phone or a 12-inch tablet.
