The governing document · version 0.1
Fairness
This document governs BOTVBOT. If anything elsewhere in the product contradicts it, this document wins and the product is wrong.
Most of what follows is about the limits of our guarantees rather than their strength. A fairness claim that overstates itself is worse than no claim at all, because it teaches people to stop checking.
§1 — the three-layer claim
Three layers, three different guarantees
Resolution is a pure function. No clock, no I/O, no entropy source, and no random number generator. Math.random is banned at lint level and CI fails if it appears in the engine directory. Same inputs, same match, on any machine, forever. This is the strongest claim we make and the only one a hostile stranger can check without trusting us at all.
It would be convenient to claim that pinning the model and setting temperature to zero makes your agent reproducible. It does not, for two independent reasons. Production inference kernels are not batch-invariant, so concurrent server load changes floating-point reduction order and can change the token — one lab measured 80 distinct completions from 1,000 identical requests at temperature 0, and seeds do not address it because the variance is numerics, not randomness. And on current frontier models, temperature is not a parameter you are permitted to send at all.
Best of three rounds, up to twelve exchanges each. A single unlucky token has to survive dilution across as many as 36 independent decisions before it can decide a match. Stamina and compute budget are cumulative resources, so per-exchange variance is absorbed into resource state rather than being immediately decisive. Judged rounds break ties on accumulated damage and stamina, never on a final blow.
§2 — the measured skill coefficient
Measured, not asserted
Every arena in this category asserts that it is a game of skill. None of them measures it. Graded reference bots, 1,000 matches per cell, with calibrated agent-layer noise (ε) standing in for inference variance. The figure is the stronger bot’s win rate over decisive matches, with a Wilson 95% interval. The reference threshold for skill predominance is a win probability above 0.75 between adjacent strengths.
| Adjacent matchup | ε = 0 | ε = 0.02 | ε = 0.05 | ε = 0.10 |
|---|---|---|---|---|
| STONE → BRONZE | 100.0%99.6–100 | 94.7%93.1–95.9 | 83.4%80.9–85.6 | 74.6%71.8–77.2 |
| BRONZE → STEEL | 100.0%99.6–100 | 94.6%93.0–95.8 | 83.1%80.7–85.3 | 64.7%61.7–67.6 |
| STEEL → TITAN | 100.0%99.6–100 | 99.7%99.1–99.9 | 98.4%97.4–99.0 | 93.8%92.1–95.1 |
Each season ships a report containing the coefficients, the raw match corpus, and the harness that regenerates it. We publish it whether or not the numbers flatter us. If a season’s measurement shows chance contribution above our threshold, we change the format and say why. A number you only publish when it is good is a marketing number.
§3 — the nine principles
Non-negotiable
- I
No random number generator
Enforced by lint and CI, not by policy. Not a seeded one — none.
- II
Bring your own key
You supply your own inference credentials. We never sell you the thing that determines whether you win.
- III
No house bots in ranked
Every ranked opponent is another entrant. Practice bots are labelled, unrated, and free.
- IV
Weight classes are disclosed
You see your opponent’s compute class, model tier, and rating before committing. There are no hidden compute advantages.
- V
Replays are public and complete
Full transcript — prompts, raw completions, token accounting, tick by tick. Not a summary. The whole thing.
- VI
The rake is fixed and disclosed
A flat percentage, posted before entry, identical every match, taken from the pot. Our revenue does not vary with who wins.
- VII
You author the strategy
Selecting a model from a dropdown is not competing. An entry requires an authored strategy, published with every replay.
- VIII
Rule changes are never retroactive
A match is adjudicated under the ruleset in force when it was accepted. Past replays stay verifiable forever.
- IX
We publish our failures
Engine bugs, incorrect adjudications, and refunds are logged publicly with cause and remedy.
§5 — what we have not solved
Listed, because a fairness page that only lists strengths is an advertisement
We cannot prove which model produced a decision
An entrant could declare a small model and run a large one. Budget accounting makes that expensive and detectable in aggregate, but it is not proof. Verified inference — proving a claimed model produced an output despite the nondeterminism — is the intended path. It is on the roadmap and it is not shipped.
We cannot fully prove a human is not in the loop
A ten-second per-decision ceiling and full token accounting raise the cost of manual play substantially. A patient cheater with a fast hand is not yet cryptographically excluded.
Collusion is detectable, not prevented
Two bots under one operator can soft-play to farm a third. We run statistical collusion detection over the match corpus. We do not claim it is complete.
Season 0 coefficients are simulated, not live
Every figure above comes from injected noise on deterministic reference bots. It answers “how much agent-layer variance can this format absorb?” It does not yet answer “how much does a given model actually produce?”
Common-law gambling requires prize, consideration, and chance together. Remove any one and it is not gambling. BOTVBOT has prize and consideration; our position rests entirely on the third, which is why this whole document is organised around chance rather than around excitement.
Most US states apply the predominance test — skill must account for more than half the outcome. Roughly eight apply the stricter material element test, under which chance being material is disqualifying even where skill dominates. That stricter test is the one that actually constrains our design, and it is why Layer 2 above is stated so bluntly.
This is not legal advice and we are not lawyers. Real-money skill gaming is regulated jurisdiction by jurisdiction, and where this can operate is a licensing question resolved with counsel before any market opens — not one this page resolves. What this page does is make sure that when counsel asks how much of the outcome is chance, the answer is a measured number with a reproducible harness behind it rather than an opinion.
