What is Zimpler and how it works in casinos
Zimpler was founded in Sweden in 2012 and is operated by Zimpler AB, a licensed payment institution supervised by the Swedish Financial Supervisory Authority. It began as a mobile billing service and reinvented itself around open banking, so today it uses bank authentication (BankID in Sweden, bank login elsewhere) to verify you and move money directly between your account and the casino. Its GO product lets you play at supporting casinos without registering, in the same way as Trustly's Pay N Play.
At a casino, you select Zimpler, enter your phone number, authenticate with your bank, choose the amount and confirm. The deposit is credited instantly. Zimpler is used in Sweden, Finland, Germany and the Netherlands and is a staple of the Nordic market.
Depositing with Zimpler
Choose Zimpler at the cashier, enter your mobile number, authenticate with BankID or your bank's login, select an amount of at least 10 and confirm. The deposit is credited immediately from your bank account. Limits follow your bank's transfer limits and the casino's caps; in Sweden, licensed casinos also apply the deposit limits you set at registration. No card or wallet is needed.
Withdrawing winnings to Zimpler
Zimpler supports withdrawals, and casinos pay winnings back to the bank account you deposited from under their closed-loop policy. Because Zimpler uses instant payment rails, funds typically arrive within minutes and at most within 24 hours of the casino approving the request. Minimum withdrawals are usually 10. At Zimpler GO casinos the withdrawal is pre-authorised to your verified account, so there is no separate KYC step.
Fees
Zimpler deposits and withdrawals are free at the casino, and Zimpler charges players nothing. Money moves in your bank account's currency, so there is no conversion when the casino account is in SEK or EUR as appropriate. Zimpler earns a perfect fee score in our rating. The only potential charge is a casino's own withdrawal fee, which is a casino policy rather than a Zimpler one.
Bonus eligibility
Zimpler deposits are eligible for welcome bonuses at every casino that offers the method. The payment is authenticated through your bank and tied to a verified identity, which gives operators no reason to exclude it, and Nordic casinos often list it among their recommended qualifying methods. Swedish regulation limits bonuses to a single welcome offer per operator regardless of method.
Pros
- Withdrawals in minutes to 24 hours
- No fees
- Phone-number login with bank authentication
- Always eligible for bonuses
Cons
- Only in Sweden, Finland, Germany and the Netherlands
- Casino appears on your bank statement
- Requires bank login during payment
- Not offered by every casino
Verdict
Zimpler is one of the best methods available to Swedish and Finnish players, matching Trustly on speed and cost with a slicker mobile flow. German and Dutch players should use it where offered. The only reason to prefer something else is privacy from your bank, where a voucher fits better, or availability if your casino does not list it.
