Battle Pass, or depending on the season Summer Pass, is a series of rewards you can unlock by playing levels and collecting “keys”. You can find it as a key icon on the left in your Home page.

You will automatically progress in the stages after beating a certain number of levels. Hard and Very Hard levels give more keys than regular ones.

There are two columns of rewards, one side is free, and the other one gets unlocked if you purchase and activate the premium pass. Premium pass benefits:

• Your maximum number of lives increases to 8 (from 5)

• You can now unlock an additional column of rewards that can be seen in the pass.
