    ROOM

    Both scores feed one Elo. One ladder. Two ranks above the floor — Demi Coder at top 15%, Master Coder at top 1%. Per-trial trophies (bronze, silver, gold) are separate visual rewards. How rating works →

    Medal System:

    Bronze, Silver, Gold per trial. Diamond is the Codigami — one trial, one holder.

    III

    Bronze

    Top 15%

    Past the entry mark. In the ranked.

    II

    Silver

    Top 5%

    Consistent, dangerous, climbing.

    I

    Gold

    Top 1%

    Reserved for the rare air.
