Tier selection
The server tier depends on the highest Luck level among players, increased by active Luck bonuses.
From Luck level to spawn tier.
The server uses the highest Luck level present, applies active bonuses, chooses a tier and then an outcome in that tier. This page separates documented thresholds from published samples.
How does the Luck Portal work?
Selection happens in three separate steps.
Brainrot selection
The game then uses the probability table for the selected tier. Exact rates are available in the dedicated guide.
Type selection
The Type, sometimes called a mutation, depends on active events and remains a separate mechanic.
The portal selects the server’s current tier.
Only when a next tier exists.
