Event predictor
Choose your unlocked islands and a week; the tool suggests an island using area bonus and event overlap.
Area bonus
+5% per week when you stay on the same island for another consecutive week. Snorlax Strength grows faster with higher area bonus.
When an island is maxed, the 5% that would go there redistributes to your other unlocked islands (e.g. +2% Cyan, +2% Taupe, +1% Snowdrop).
