Tiers
Free: any X account, 1 game a day. Tier 1: 10 a day. Tier 2: 50 a day plus remixes. Tier 3: unlimited inside the global daily cap, front of the queue.
Tier thresholds are set at launch and shown here from config. The balance of your linked wallet is read live from chain (cached 60 s).
Linking is one signed message, never a transaction: it states your X handle and id, the wallet, a nonce and the time. One wallet per X account, 24 h relink cooldown.
Global caps: 120 builds an hour, 1500 a day, 5 per account an hour (tier 3: 20).
