1win Casino at a glance

1win Casino is the operator we recommend for playing the Big Bass Bonanza series for real money. The bonus, the limits and the payment information on this page are given in US dollars. Availability, currencies and payment methods depend on the country you play from, so check the casino terms for your location before you register.

We review the casino from the point of view of a Big Bass player: how the welcome bonus fits these slots, how easy it is to deposit and cash out, and what to check before you play. The key numbers are collected in the table on this page and are repeated below where they matter.

Welcome bonus and wagering

New players get 100 % + 70FS on the first deposit. The free spins are credited on Big Bass Bonanza, the game that started the series.

The bonus comes with a x35 wagering requirement. Before you accept it, check in the bonus terms what the multiplier applies to. If it applies to the bonus amount only, a $100 bonus means $3,500 in bets before the bonus money can be withdrawn. If it applies to deposit plus bonus, the turnover doubles.

Also check three more points in the terms:

  • the maximum bet allowed while the bonus is active;
  • how many days you have to complete the wagering;
  • whether winnings from the free spins are capped or have their own wagering.

Big Bass slots are highly volatile, so wagering can take a long time and the balance moves in jumps. If you prefer to keep things simple, you can decline the bonus and play with your own deposit only.

Big Bass slots at the casino

The casino offers the Big Bass games by Pragmatic Play, including the original Big Bass Bonanza and its sequels. Every game reviewed on our site can be tried first in the free demo, with the same rules and maths as the real-money version.

One thing to check in every game: Pragmatic Play releases slots in several RTP versions, and the operator chooses which one to run. Open the info screen (the “i” button) in the slot and compare the RTP with the value in our review before you play.

Features such as the Bonus Buy and the Ante Bet depend on the jurisdiction. If a feature from our review is missing in the casino lobby, the operator has switched it off for its market.

Deposits and withdrawals

Parameter Value
Currency US dollar (USD)
Minimum deposit $10
Payment methods Visa, Mastercard, Apple Pay, Google Pay
Withdrawal time Up to 24 hours

The minimum deposit of $10 is enough to try the slots at the lowest bets: most Big Bass games start at $0.10 per spin.

Withdrawals usually go back to the method you used for the deposit. Licensed operators verify a player’s identity before paying out, so the first withdrawal can take longer than the next ones. Upload your documents in advance to avoid delays.

Licence and safety

Online gambling rules differ from country to country. Before your first deposit, find the licence details in the footer of the casino website and check them in the regulator’s public register. Make sure the casino is allowed to accept players from your country.

A licensed operator works under the supervision of a regulator and has to verify the age and identity of its players. If the licence cannot be confirmed, do not deposit.

How to start playing

  1. Open the casino through the “Play for real money” button on this page.
  2. Register and confirm your phone number or email.
  3. Upload your documents for verification.
  4. Choose whether to take the welcome bonus and read its terms.
  5. Make a deposit from $10 and open any Big Bass slot from the lobby.

Responsible gambling tools

Gambling is entertainment, not a way to earn money. In the account settings you can set deposit limits and take a break, and self-exclusion is available if you need to stop completely. Set a budget before you start and do not try to win back losses.

If gambling stops being fun, take a break and ask for help. More information is on our responsible gambling page.
