Iron Soul Dungeon "Code Limit Reached": What It Means

Why the message appears

Iron Soul: Dungeon limits how many code redemptions a single account can make before it stops accepting new ones. Because the limit sits on your account rather than on the code, three things follow:

The exact number of redemptions in a window is not published by the developer or the official wiki, and this site will not invent one. What is documented is the behaviour: the block is per account and it lifts on its own.

Spend your redemptions in the right order

If you are going to hit a cap, hit it on the codes that pay best. Of the 11 currently working codes, these carry the largest recorded bundles:

The full list, including the codes with unlisted bundles, is on the codes page.

Other reasons a code fails

Is this a ban?

No. The experience description states that cheating and exploiting result in a permanent ban, which removes access to the game entirely. A code limit message leaves everything else working — you can still play, forge and claim quest rewards.
