Fast reaction & Concentration Game - Infinity Run

Rating: 7/10 - 1 votes

Infinity Run is a fast-paced and unforgiving endless-runner game. Where you play as a circle and have to go through a track to collect points and gems while lasting as long as you can. You can change your shape to a square and back to a circle. Destroy other opponents by being of the same shape to get extra points

How to Play: Control your ball to go through the shape-changing obstacles and eliminate other racers. If you go through the circle-shaped obstacle while being a ball, you will turn into a square, and if you are a square and go through the square-shaped obstacle you turn into a ball again. It's easier to stay as a circle in the beginning, as most of the other runners are of the same shape. Change once you have progressed to avoid crashing with the other shapes and losing the round.

The game can be played on PC and mobile browsers. Use your keyboard’s arrow keys, or touch your screen to move around the track.

Note: If playing on a mobile device, click 'OK' if a popup message comes up and the game will work perfectly fine. During your first attempt on mobile it might lag slightly, the game should work perfectly fine after your first attempt.
