Make a first deposit of €25 or more and RioAce doubles it - 100% up to €500 - then adds 100 free spins on the Le Cowboy slot. RioAce belongs to the same operator group as Lollyspins and Casabet, but it is a separate casino with its own domains, support and a lobby of more than 12,000 games from 97 providers. The bonus most often slips past people who deposit too little: you can top up from €20, but the bonus starts at €25.
Slots count 100%; roulette, blackjack, baccarat, video poker and other table games count nothing. Some slots count only 20%, around 120 popular ones, including Book of Dead and Starburst, are locked while a bonus is active, and the live casino is closed to bonus play. On the maximum €500 bonus, 40x means €20,000 in bets within ten days - a long road. Our wagering requirements guide shows how to work out and pace a target like this.
RioAce also pays daily real-money cashback of 10% to 35%, depending on VIP level (30 levels).
Worth knowing: each deposit has to be wagered three times before any withdrawal, even without a bonus. With a €500 cap per request and only one request per 24 hours on some methods, a €2,000 win takes at least four requests. The first withdrawal needs proof of identity, address and payment-method ownership - our verification guide explains the check.
RioAce operates under a Curaçao licence.
RioAce's own site says only that it is regulated, naming no issuer, licence number or operating company.
What this means in practice:
