Rialto Casino Welcome Offer September 2026: Spend £10 Get 100 Free Spins

Sep 10th, 2026 8:45 AM EDT

Rialto Casino is a newer name for UK players, but its welcome offer is refreshingly easy to get your head around. New customers can pick up 100 free spins on one Big Bass title after spending £10, with no promo code to enter. It's a nice addition to the list of the best UK online casinos welcome bonuses, and one that keeps the terms short enough to read in a minute.

The free spins are specifically for Big Bass - Hold and Spinner, one of the better-known fishing-themed slots in the series. If you're a fan of Big Bass free spins, it's a decent way to have a go at this version without putting more than the initial £10 at risk.

Rialto Casino Bonus	Spend £10 Get 100 Free Spins
Rialto Casino Promo Code	Not required
Minimum Deposit	£10
Eligible Game	Big Bass - Hold and Spinner
Bonus Wagering	10x
Maximum Free Spins Win	£200
Payment Methods	All except PayPal and Paysafe
Terms and Conditions	New players only. Minimum deposit £10 (excluding PayPal and Paysafe) and spend £10 to get 100 Free Spins on Big Bass - Hold and Spinner. 10x wagering. Maximum win £200. 18+. T&Cs apply.

There's a £10 deposit requirement and a separate £10 spend requirement, so simply putting the money into the account isn't enough to trigger the spins. You need to play through the £10 on qualifying games first, which puts Rialto in line with other 10 minimum deposit casino offers where the entry point is kept deliberately low. PayPal and Paysafe deposits don't qualify either, so you'll need to use another payment method if you're claiming the offer.

The 10x wagering requirement applies to winnings from the free spins, while the bonus has a £200 maximum win. That's something to bear in mind given the Big Bass series can produce some sizeable multipliers. It's worth checking how the cap stacks up against other casino bonuses before deciding where to play. Any winnings from the free spins above £200 won't be paid out.

How to Claim the Rialto Casino Free Spins

Register a new Rialto Casino account.
Deposit at least £10 using a payment method other than PayPal or Paysafe.
Spend £10 on qualifying games to trigger the offer.
Receive 100 Free Spins on Big Bass - Hold and Spinner.
Complete the 10x wagering requirement on any winnings, subject to the £200 maximum win, before withdrawing.

Rialto Casino Free Spins Terms and Conditions

This is a new customer offer, and the excluded payment methods apply to the qualifying deposit rather than withdrawals. That means PayPal can still be used to cash out later, even though it can't be used to claim the bonus.

Players who like to compare casino payment methods before signing up will find Rialto's approach fairly typical for the UK market. The £200 maximum win applies to winnings generated by the free spins and is separate from any other funds in the account.

The £10 spend is tracked separately from the deposit, so withdrawing before you've played the full qualifying amount could mean the offer never gets credited. If you're claiming the bonus, make sure the full £10 has been spent on eligible games before requesting a withdrawal. Players should also check the site's typical processing times if a fast withdrawal casino matters to you.

Why Join Rialto Casino?

Beyond the welcome spins, Rialto Casino offers a mobile-friendly platform with a broad mix of slots and live tables from major studios. It also has the usual UK responsible gambling tools, including deposit limits and self-exclusion through GAMSTOP, which puts it among the more reliable and safe online casino options for new UK players.

For players looking for a relatively low-commitment way to try a familiar slot series, the welcome offer is simple enough without a long list of hoops to jump through.
