Cartoon Network is the best place for Johnny Test games! Can you handle the Tests of Time? Johnny "borrowed" Susan and Mary's Time Travel Teahouse and accidentally crashed it. The only way to fix the time machine is to collect the missing time circuits. Use Johnny's time clones to solve the time puzzles before it's too late!

Johnny Test is always ready to test any crazy experiments his genius sisters Mary and Susan come up with. Joined by Dukey, who's both a loyal dog and best friend, Johnny never knows what kind of strange powers or weird side effects will happen when he becomes a test subject in his sisters' laboratory.
