To open the Jokes on you! case, you need to charge it with a special item – a Joker Smile.
Each case on our site has a small chance of dropping a Joker Smile. The more expensive the case that the Joker Smile dropped from, the more charges you’ll get for Jokes on you!
For every three Joker Smile charges, the case will level up and the items in it will get even better!
Note that the case level cannot be lowered, and after the Jokes on you! case is opened, all used and unused case charges disappear.
