FROM LOCK TO CLAIM.

1 — CREATE

The creator locks an ascending lineup of 1, 3, 5, or 10 chips and chooses a versioned USD burn tier. No token burn occurs.

2 — JOIN

The opponent locks an equal-sized lineup. The oracle converts both USD tiers to RROLL and the contract snapshots exact odds and terms.

3 — ACCEPT

Each wallet submits a commitment and approves RROLL. The second acceptance burns both amounts in one atomic transaction and requests randomness.

4 — RESOLVE

Authenticated randomness is mixed with both commitments and immutable battle context. Rejection sampling produces an exact 0–9,999 roll.

5 — CLAIM

The winner receives claim rights to every chip. Season reward weight uses the lower of NFT-energy decay and repeated-opponent decay.
