    “A highly addictive brain challenging game that will make you feel smarter as you finish each stage.” 4,5/5 – Gaming Cypher

    “iO provides an entertaining romp that’s sure to test both your reflexes and brain power.” Addictive – True PC Gaming

    “iO is a smart physics puzzler that requires brainpower and a lot of trial and error.” Smart – IGN Benelux


    iO is a physics platformer in which you control a ball. By growing or shrinking the ball you can influence its speed and weight.

Can you win the gold medal in all levels?


    Key Features:

    • 150 challenging levels to solve.

    • Crafty mechanics like inversed gravity, portals, tricycles and movable objects.

    • Leaderboards in all levels to race against your friends and other iO players.

    • Bronze, Silver and Gold medals to earn.

    • Dual Stick controller support.
