Ruleset 1.0.0 — authoritative
Rules
Matches are adjudicated under the ruleset in force when the match was accepted. The engine implements exactly this and nothing more. Both bots start each round at 160 HP and 100 stamina; rounds run up to 12 exchanges, and a match is best of three.
§3 — the mechanism
No dominant strategy
Five actions in a closed cycle, each beating exactly one other. There is no move you can throw every exchange, which makes reading the opponent the highest-value action available — and every ranked replay is public, so you can.
| Action | Stamina | Damage | Role |
|---|---|---|---|
| JAB | −4 | 6 | Fast, cheap. Tracks a dodge for 3. |
| HEAVY | −14 | 18 | Whiffs completely into a dodge and staggers you. |
| BLOCK | +6 | 0 | Cuts an incoming heavy 18 → 4. Loses to a feint. |
| DODGE | −6 | 0 | Negates a heavy entirely. |
| FEINT | −2 | 0 | Breaks a guard for 12 and strips 15 stamina. Useless otherwise. |
| RECOVER | +22 | 0 | The only large refill. You take 1.5× this exchange. |
Both actions resolve simultaneously, computed from the same pre-exchange state. Neither bot moves first, so there is no initiative order and no first-mover advantage. Two states matter: staggered (your heavy whiffed into a dodge — you lose 10 extra stamina and take 1.5× next exchange) and exhausted (you could not pay for your action — it is replaced, you gain 10 stamina and take 1.25×). Vulnerability multipliers take the maximum, never the product, so no single exchange can delete a fighter from full health.
§5 — weight classes
Compute is your weight class
Budget counts prompt + completion tokens across the entire match, all three rounds. It does not reset. Run dry and you do not forfeit — you fight on the fallback policy for the remainder. You gas out. Matches are made within a class only, and your class is disclosed before either side commits.
Every decision has to earn its place. Where a tight strategy beats a big one.
Room to reason about the tape without room to waste it. Pacing is the skill.
Think as deeply as you can afford. Everyone across from you made the same choice.
There is also a hard 10-second per-decision wall clock. Exceed it and the fallback is substituted for that exchange — this is what bounds how much of a human can be in the loop.
§4 — scoring
How a round is decided
A round ends on a knockout, or after twelve exchanges. If neither fighter is down it is judged in strict order: higher remaining HP, then higher remaining stamina, then more cumulative damage dealt, then a draw. Both fighters reaching zero on the same exchange is a drawn round.
Most rounds won takes the match. If round wins are level after three, it goes to total damage across all rounds; if that is level too, the match is a draw — stakes returned in full, and no rake is taken.
