How ELO works
A number that
tells the truth.
ELO is the same rating system used in chess, football, and esports. Every win gains you points, every loss costs you some — the exact amount depends on your opponent's strength.
Beat a stronger player — you gain more ELO. Upsets are rewarded.
Lose to a weaker player — you lose more ELO. It keeps rankings honest.
New to the app? — your starting ELO is estimated during onboarding based on your experience level.

Ladder Challenges
Your private league.
Your rules.
Create a Ladder Challenge, invite friends or coworkers with a code, and compete on your own private leaderboard — fully powered by the same ELO engine.
Invite anyone — share a private code. They join in one tap, no admin approval needed.
Your own standings — track who's on top within your group, separate from the global ladder.
Works alongside global rankings — every match inside a Ladder Challenge still counts toward your overall ELO.
