Infinite Dungeon checkpoints?

I’m stuck on floor 48. I’ve gotten up to 62 before, but no checkpoint in 14 floors is a lot. Where is the next checkpoint? Are they not at regular intervals?

63-80-99-120 I see that Ashley already said the mathematic answer in a old post but can’t remember !

Basically, Blix, Aethin and Ashley are to blame for that change during the beta

no it’s n^2 - 1

so it will be

2^2 - 1 = 3

3^2 - 1 = 8

4^2 - 1 = 15

and so on

It’s actually n(n+2) where n is the checkpoint u want…

They both work out to give the same answers, actually. However, the n^2 - 1 one is for the true checkpoint number plus one. (E.g. 2^2 - 1 = 3 is the first checkpoint, where n = 2).
