Open the codes menu
Iron Soul Dungeon places code redemption in the lobby, behind a gift icon on the main menu. Codes are case-sensitive, so the copy buttons next to each entry on this site reduce mistakes.
Redeem before you grind
Many codes give Cave Tickets or Race Rerolls. Claim them before you start a farming session or a reroll streak to avoid wasting time without the bonus resources.
Watch for expired codes
Codes expire silently. The codes page on this site separates active from expired entries. If a code no longer works, check the newest update notes - it may have been retired.
