Prioritize spinning the Yin & Yang Wheel hourly to maximize your chances of getting rare items like the Yin Yang Lamp or the mutated Bisonte Giuppitere.💡
Try to acquire or steal mutated (black & white) Brainrots from others while the event is active.💡
Participate in Dul Dul Dul Rituals as soon as they become available to unlock secret Brainrots quickly.💡
Focus on gathering materials for the new craftable Brainrots: Los Primos and Karker Sahur.💡
Clear inventory and make space for new Brainrots / rewards before the event starts.💡
Don’t waste resources on low-value Brainrots once the mutation is available—focus on upgrading mutation candidates.💡
