Questions about this offer
Do I need a promo code for the Bigthunderslots offer?
No. Bigthunderslots does not publish a code for this promotion — the conditions above are the whole of it. Any “exclusive code” offered elsewhere is not from the operator’s page.
How much do I have to pay in?
The page states a minimum deposit of £10. Paying in less does not trigger the offer, and paying in more does not increase it unless the terms say so.
Can I withdraw the winnings straight away?
Yes. The operator states there is no wagering requirement, so winnings can be withdrawn like any other balance, subject to the usual identity checks.
When does it end?
The page gives no end date. It runs until the operator withdraws it, and this site records the day that happens.
Which games does it work on?
The terms name Big Bass Splash. Play outside that list and the stake may not count — this is the condition people most often miss.
Is this offer available to existing customers?
No. The terms limit it to new accounts or a first deposit. Existing customers should look at the operator’s reload and weekly offers instead.
