How Elo Works Here
Ratings are updated as pairwise Elo inside each multiplayer match. Every rated participant is compared against every other rated participant, then all pair deltas are summed.
- Winner vs each loser uses actual scores 1.0 (winner) and 0.0 (loser).
- Loser vs loser is modeled as a draw: 0.5 and 0.5 for that pair.
- Pair formula: delta = K * (actual - expected), with K = 24.
- Expected score formula: 1 / (1 + 10^((opponent - yours) / 400)).
- Each participant's match Elo change is the sum of all pair deltas involving that participant.
Bots start at 1200 Elo. Humans start at 1600 Elo, which is 400 points above the bot baseline. Mixed bot-vs-human matches update both leaderboards from the same underlying match result.
Important: 0.0/0.5/1.0 above are pair scores, not Elo points. Elo points can be positive or negative based on (actual - expected). If you beat a much stronger opponent, you gain more; if you beat a much weaker opponent, you gain less.
