During the event period, any spin in any slot can trigger the Level Devil feature.

When activated, it's icon will appear on the left of your game screen, with other special features.

Level up and reach the Level Devil goal to play the Mother Lode mini-game.

During the Level Devil countdown, any purchase in the player store can get you 2 hours of double experience buff

Remember, the Level Devil is a timed event so complete the goal before time runs out!

When the countdown timer runs out and you've completed the required level ups, you can play the Mother Lode mini-game.

You can either play it right then or press the "x" and send the bonus game to your inbox to be used later.
