Questions about this offer

Do I need a promo code for the Sportingindex offer?

No. Sportingindex 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 no minimum deposit for this promotion. Registration, opting in or verification is what qualifies you.

Can I withdraw the winnings straight away?

The page does not state a wagering rule for this reward, so check the operator’s general promotion terms before assuming the winnings are free to withdraw.

When does it end?

The page gives an end date of 2027-05-31. Operators do pull promotions early, so the date is a limit, not a promise.

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.
