Interwetten Casino Review: Offers, Payments, Licence

The welcome bonus of 100% up to €200 asks for the deposit once and the bonus five times within 30 days, with no cap on its winnings, though casino games count 20% or less toward that wagering. After it, eight recurring offers keep running: a Loyalty Bonus reload of 50% up to €400, a live casino weekend cashback up to €500, a daily Spin and Win wheel and weekly offers on Evolution blackjack, roulette and Crazy Time.

Banking is the lowest-scoring part of the review. Deposits run through 16 methods, but withdrawals go back only by Visa, Mastercard or bank transfer, from €30, with one free payout per calendar week and a €5 fee after that, and Crypto Pay by Bitpanda is the only crypto option. Support works by email and phone around the clock, in English and German. Interwetten suits a player who wants a wide slot and live casino lobby on the same account as sports betting, and who is happy to cash out by card or bank.

Before a withdrawal, the deposit has to be wagered once and the bonus five times, within 30 days, otherwise the bonus is deducted from the balance. Casino games count 20% or less toward that requirement: slots, grid slots, 3D slots, scratch cards and Megaways count 20%; roulette, virtuals, game shows and lottery 6.6%; blackjack, video poker, baccarat, poker and crash games 3.3%. Sports bets at minimum odds of 1.7 count 100%, and system bets do not count. Once a withdrawal is requested during the bonus period, later deposits stop qualifying for the bonus, although open bonus amounts stay playable until the period ends. Winnings from the welcome bonus are not capped.

Every new account also receives a €5 Free Bet on Book of the Fallen by Pragmatic Play, worth up to 50 spins, credited automatically on registration with no deposit. The game has to be launched within 14 days of registering and the Free Bet accepted, and the bonus amount is wagered three times, including a real money share, before a payout.

Eight recurring promotions run alongside:

• €400 Casino Loyalty Bonus: a deposit reload of 50% up to €400 on one deposit in the promotion period, from €10, selected on the deposit page. The deposit is wagered 15 times within 14 days on casino and live casino, and the bonus is released in 5 steps, each credited as cash and wagered once before a payout. Slots, soft games and virtual sports count 100%, roulette 25%, blackjack and baccarat 15%, video poker and casino poker 10%. It is not available to customers from Cyprus, and the current period runs until 26 October 2026.
• Live Casino Weekend Cashback, up to €500: activated with the button on the promotion page, it applies to net weekend losses of at least €100 on live casino tables between Friday 00:01 and Sunday 23:59. It is credited on the first working day after the weekend and wagered three times with a real money share, and only one person per IP address, household or address can take part.
• Spin and Win: one spin a day on the wheel for players who have deposited at least €50 in the last 30 days. Prizes are random: a cash bonus turned over once, a slot free bet on Book of the Fallen or a football or tennis free bet wagered three times, or no prize, and they must be accepted and used the same day by 23:59 CEST.
• Game of the Month: stake €100 on the game of the month between Friday and Sunday and deposit at least €25 that weekend for a €10 Free Bet on the same game on Monday at 2pm, wagered three times. The current game is Interwetten Pyro Piggies Hold and Win by Kalamba Games, from 2 October to 1 November 2026.
• Make it Right Monday: €50 staked on Pyro 7s by Kalamba Games on a Monday brings a €5 free bet on the next working day, valid for one day; under the general terms, free play winnings are wagered 3x.
• Blackjack Tuesday: on Tuesdays from 14:00 to 23:59 CET, Bonus Cards at the Interwetten Blackjack tables by Evolution pay up to €105 in total, credited the next working day.
• Lucky Streak Roulette Wednesday: €30 for six winning straight-up bets on a red number (minimum €1), up to twice per Wednesday for €60, on Evolution live roulette, with Double Ball, First Person, American, Instant, Red Door and Fireball roulette excluded.
• Crazy Time Cash Hunt Friday: from 12:00 CET on Fridays, a stake of at least €5 on Cash Hunt in Crazy Time earns a €20 Lightning Storm bonus by Evolution each time the Cash Hunt round is reached, up to twice per Friday (€40). The bonus is valid until Sunday 23:00 CET, and winnings are capped at €1,000 per voucher.
