NewRolly's Rollies

Set your criteria (species plus spread, subskills, nature, friendship). Results update automatically from 1,000 simulated "catch until you get one that matches" trials using the same RNG as NewRolly's Unlimited Biscuits. You need at least one criterion to run.

Your criteria

Set at least one of these. We count how many catches until you get a Pokémon that matches everything you set.

Subskills (max 5)

Add up to 5 subskills and optionally restrict which level slot(s) they can be in.

Friendship & guaranteed gold

In Pokémon Sleep, catching the same species builds friendship. At badge thresholds (bronze → silver → gold), the game guarantees a gold subskill in certain slots. This simulator tracks friendship as you catch, applying gold locks dynamically — just like the real game.

Your gold lock preferences (silver badge+)

Bronze badge (Lv10 gold lock) is automatic — the sim applies it as soon as friendship reaches the threshold, just like the game. Once you earn silver badge, you choose whether to lock gold at Lv25. Same for gold badge and Lv50. These preferences apply once the badge is earned during each trial.
