With the help of a heavy ball in the game Gem Runner, you can collect as many gems as you have the dexterity and patience to do. Roll the ball using the right or left arrows. This way you can direct the movement of the ball, forcing it to go around dangerous obstacles- red cubes and collect multi-colored crystals. If you make three cube collisions, the Gem Runner game will end. If you are dexterous enough, the game time can last indefinitely.
