If the game freezes, just click inside it (games can get unresponsive if you click elsewhere on the page).
A game that puts the quickness of your reaction to the test. In the red bar below, you'll see a white cube moving fast from the left to the right. Try to click in the middle of the bar, exactly when the white cube is in the middle and the yellow smiley's forces are the strongest. The yellow, 'good' smiley then has the best chance of beating the red, 'devilish' smiley.
This game is played with mouse only.
