Every mutation has its own checklist. Your progress is saved privately in this browser and your previous Checklist selections are preserved.
How the Brainrotdex Checklist works
Select a mutation, then click every Brainrot you already have indexed. Collected Brainrots stay colored while missing ones remain dark. Use “Show missing only” to immediately see what you still need to request or obtain.
Normal, Gold, Diamond, Rainbow, Crystal, Phantom and every event mutation are tracked independently. This private checklist does not change public exist counts or trade values.
