What this profile flair means
Elite peak aura
The nameplate aura reflects a highest recorded league average of 224.
Perfect Game Bowler
Awarded for recording a sanctioned 300 game.
Honor pins
Each pin names a recognized honor and shows how many times it was earned.
Milestone marks
These celebrate peak average, career average, recorded games, and accumulated honors separately.
Roster matching
League Finder
Start with one bowling center, then expand across the region. Matches use name, average, gender, game count, and league history when available.
These are evidence-based suggestions, not confirmed identities. Your “likely” or “unlikely” choices last only for this browser tab and are never attached to the profile.
