FRESH Casino

First deposit bonus, 100% up to €600 and up to 500 free spins

Min deposit: €20
Wagering: 40x the deposit plus bonus (D+B)
Max cashout from bonus: ten times the bonus amount
Bonus type: not sticky. The bonus moves to your cash balance once the wagering is met
Max bet: €5 of any single bet counts toward the wagering. A larger stake is allowed and the rest does not count
Deposit to max it: €600, at the 100% rate
Free spins: up to 500 on Gates of Universe, banded by deposit from 50 at €20
Free spin wagering: 30x on what the spins win, with the same ten times cap
Eligible games: slots only at 100%. Jackpot slots, Real Money slots and slots with adjustable volatility all count zero, as does every other game
One at a time: one bonus active per account, so the steps are wagered in turn
If you withdraw early: a withdrawal request before the wagering is met cancels the bonus and any bonus winnings above the bonus amount
Country variations: players in Finland have €3 of a bet counted rather than €5

How to claim:

  1. Open the cashier and select the first deposit bonus before paying.
  2. Deposit €20 or more; €300 is the smallest deposit that collects all 500 spins.
  3. Clear 40x on slots, where €5 of each bet counts toward it.
  4. The bonus moves to your cash balance, up to ten times the bonus.
