# MUTT — machine-readable rules

> One bone. 32 mutts. Only one eats.
> A dog-fighting knockout on BNB Smart Chain (chain id 56). No token, no emissions, no yield.

## What a player does

1. Own 3 MUTT dogs (ERC-721).
2. Enter a room: 3 token ids + 3 strategy codes + $1 in BNB.
3. Room closes on schedule; the bracket resolves; champion is paid automatically.

Dogs are never consumed. They do not die, level down, or lose stats.

## Dog stats

Every dog has three uint8 stats, rolled at mint from `keccak256("mutt-stats", tokenId)`, base ±5:

| breed   | PWR | SPD | SKL | supply |
|---------|-----|-----|-----|--------|
| Ironjaw | 80  | 35  | 65  | 600    |
| Boulder | 70  | 30  | 80  | 500    |
| Gale    | 55  | 85  | 40  | 500    |
| Shadeclaw | 45 | 75  | 60  | 450    |
| Wisp    | 30  | 95  | 55  | 400    |
| Ember   | 70  | 55  | 55  | 400    |
| Frostfang | 60 | 60  | 60  | 372    |
| Wraith  | 50  | 68  | 72  | 111    |

Total supply 3,333: 3,033 for sale, 300 reserved for free-lane champions.

Prices by serial: 1–1,111 = $2, 1,112–2,222 = $3, 2,223–3,033 = $4 (USD, paid in BNB at the launch rate).

There is no admin setter for stats or supply. What a dog is at mint is what it stays.

## Strategy codes

| code | name   | effect |
|------|--------|--------|
| 0    | ATTACK | damage x1.12, damage taken x1.05 |
| 1    | GRIND  | damage x0.95, damage taken x0.85 |
| 2    | AMBUSH | damage x0.95, dodge +10%, crit +18% |

## Fight resolution

- 3v3 per match. Fastest living dog acts first.
- Hit target is the opposing dog with the lowest current HP.
- damage = (PWR + SPD*0.45) * strategy_atk - defender_SPD*0.5
- crit chance = SKL/250 (+0.18 for AMBUSH), crit damage x1.5
- dodge chance = SKL/400 (+0.10 for AMBUSH)
- HP = 120 + SKL*1.6
- A match ends when one side has no dogs left.

Room bracket: 8 teams, three rounds (8 → 4 → 2 → 1). Short fields are filled with byes, never bots.

## Economy of one room

8 seats x $1 = $8 pot.

| recipient | share |
|-----------|-------|
| champion  | 65%   |
| runner-up | 15%   |
| house     | 10%   |
| next room | 10%   |

If a house bot ever wins, the entire pot rolls into the next room and nobody — including the house — is paid.

## Free lane

Off-chain, one entry per wallet per day, no NFT required. Champion receives one real dog (from the 300 reserved). No cash prizes.

## .ai Agent ID

Optional. Wallets holding a Binance `.ai` Agent ID show their handle in results and get a second free entry per day. No Agent ID is required to play.

## Contracts (BNB Smart Chain, chain id 56)

- Dogs (ERC-721 "MUTT"): 0x73Fd7b0904B8E7e8d2940194C66cC74863a28330
- Rooms: 0x8163D007dD678608cb440c1aF2d1ca52aAfd8C5F

Mint is live: `mint(uint256 count, uint256 maxBnb)` payable, count 1..3, price = USD tier at `quote(count)`.
Rooms take `enter(uint32 roomId, uint256[3] ids, uint8[3] strats)` with 0.0014 BNB per team.
Strategies: 0 = ATTACK, 1 = GRIND, 2 = AMBUSH.

## Fairness

- Results are signed by an oracle key and verified on-chain.
- The fight seed comes from a block produced after entries close, so neither the operator nor the players can know it in advance.
- The simulator that produces results is deterministic: same seed, same teams, same strategy codes → same bracket, on any machine.
