Jeff's Mysterious Experiment is a limited-time event where players compete against others.
Tapping the Start button on the Jeff's Mysterious Experiment screen allows players to join the event. 
Players will be randomly matched with four other players and receive unlimited Clovers for 20 minutes.

Using Magic Balls during a level will automatically grant Magic Ball Reagents. 
Failing a level causes players to lose all collected Magic Balls.
Players can compete for the top spot in the rankings by collecting more Magic Ball Reagents than other participants.

Jeff's Mysterious Experiment unlocks at Level 36.
