Case Simulator: Steal the Brainrot!

Case Simulator: Steal the Brainrot! is all about cracking cases and building up a brainrot collection. You start with simple cases, fill your inventory, then move on to sets with a higher chance of better pulls. The goal is to collect every brainrot and finish all the collections. Duplicates drop a lot, so you shouldn't keep everything. Sell off extras, rack up cash, and keep opening cases nonstop. Can you complete the whole set and pull the rarest brainrots?

How to play?

At the start, you get cases, including a free starter set. Different cases contain different brainrot sets, so pick the case that matches what you want, open it, and the dropped item goes into your inventory. Then go through your inventory and decide what to keep. If you don't need a brainrot, sell it and spend the money on more cases. That way, you level up faster and see rare brainrots more often without clogging your inventory with duplicates. When in-game events pop up, jump in and check them out — they often boost your chances of getting the cases you're after.
