Wagering explained

Wagering is 45x. With a $15 deposit, the playthrough is $15 × 45 = $675. The terms do not list a maximum cashout, so the cap on what you can withdraw is unknown. The terms do not list an expiry, so there is no stated deadline to clear the wagering. The terms do not list a maximum bet, so no figure limits individual stakes. The match rate is missing, so the bonus amount at each deposit level is not published. The $3,400 figure is a ceiling, not a promise.

My thoughts about 21Bit Casino Up to $3,400 + 100 Free Spins Bonus Codes

I would take this if I already play slots at 21Bit Casino and want 100 free spins alongside a deposit. I would skip it if I need to know the cashout cap before I play, because the terms do not list one. The 45x wagering is the rule that decides the cost: $15 at 45x is a $675 playthrough, and the missing match rate means the bonus amount at each deposit level is not published. My main worry is the missing cashout cap, not the headline. Play within your budget, and remember 18+.
