Tic-Math-Toe is a fun game that uses the game Tic-Tac-Toe to help kids add, subtract, multiply, or divide either whole numbers or integers very quickly. The goal of the game is to solve equations to get three answers in a row correct. These correct answers can be horizontal, vertical, or diagonal. However, this is either a one or a two player game. If two players play, each student must also block the other player from winning.
I personally enjoy this game a lot. The difficulty level can be set by grade level from kindergarten to 6th grade. Another fun arithmetic game to try is Spot Kicker.
This game can be played on any device, but I believe it requires an updated version of Flash.
