“Grav” is an awesome game, and it is very addicting. The basic premise is that there is a ball that obeys the normal laws of gravity and inertia, but there are different tiles that influence the game. There are tiles that push the ball away from them, tiles that bump the ball away, and spiked tiles to avoid. The large variety and the 110 progressively more difficult levels make it a very addicting game, a combination of puzzle, strategy, and reflex.

“Grav” is by far one of the best games that has ever been released for a calculator. It might not be as exciting as an action or racing game, but “Grav” is an original idea that has been executed extremely well in grayscale. The point of the game is this: you are a ball in a gravity environment where you must accelerate away from pointy objects that can destroy you. Although it sounds simple, the game's 150+ levels get so difficult that the gameplay focuses on your strategy for getting through the levels. There are also gravity wells push you away towards bombs, and in some courses, you can bounce very high.
