Once you visit the cashier and make a deposit of at least €1, the bonus will then be yours. You must choose the Welcome Offer either when you establish a new account or when you make your first deposit into it if you reside in an eligible nation and wish to benefit from it. If you deposit €100 and receive the Bonus, for example, you must bet €500 (100 X 5 = 500) on multiples before you may withdraw your winnings. The 22bet Bonus terms and conditions say that you must wager the Bonus amount five times (5x) on accumulators with a minimum of three selections and odds of 1.40 apiece before you can withdraw any profits.
Of course, it has specific wagering requirements, just like any Welcome Offer. The funds will be credited to your account when you make a qualifying deposit.
