You must always beat the previous level in order to unlock the next one.
If the next level is covered by a metal cage, known as a "gate," you will need to fulfill certain requirements to get by.
To get past the gate, simply tap the level and either open cages with your keys to get more fiends or upgrade the required number of Fiends to the required levels. If you do not have the resources to upgrade your fiends, you will be given the option to play Lootballoon levels.
We aim to add 20 new levels each week and exciting new content each month with our updates!
If you've run out of levels and are waiting for an update, then you can always play the Earthworm levels, Daily events, Fiend quests and Lug's Lootballoon.
