Time Stopper 3D is a free casual running game developed by MondayOFF for Android devices. The game is designed to be simple and easy to play, but it is surprisingly difficult to master. The game features a runner who is on a mission to become the best runner in the world.

The game is set in a 3D environment, and the player has to navigate the runner through different obstacles and challenges. The controls are straightforward, with the player swiping left or right to dodge obstacles and tapping the screen to jump over hurdles. As the player progresses through the levels, the game gets harder, and the obstacles become more challenging to overcome.
