Welcome Bonus

Mermaid's Diamond Slots

September 20, 2025 — RTBet Casino has rolled out a refreshed welcome package for new players: a 100% deposit match up to $500 plus 200 extra spins. The spins are paid out as 20 per day over 10 days, with the first 20 credited immediately after your qualifying deposit. To claim, register an account and make a real-money deposit; specific minimums and full wagering terms apply, so check the bonus terms before you opt in.

What the welcome offer actually delivers — and how to claim it

The new welcome offer combines a cash match and a large free-spins bundle. After signing up and making your first deposit, RTBet will match that deposit dollar-for-dollar up to $500. The 200 free spins arrive in ten installments of 20 spins each, giving you a steadier stream of play instead of one-time crediting. Immediate access to the first 20 spins lets you start playing the same day you deposit.

Be aware that bonus funds and free spins are subject to the casino’s terms and conditions. Minimum deposit requirements, wagering rules, and game restrictions may apply. If you want the quickest path to the bonus, follow the prompts during registration and confirm any opt-in boxes at deposit.

Where to use your spins and which games qualify

Free spins are intended for slot play. RTBet features titles from major providers including Play’n GO, NetEnt, Pragmatic Play, Evolution, and others, so you’ll find a wide selection of slot machines eligible for promotional spins. One popular choice on the site is Mermaid’s Diamond Slots by Play’n GO, a 5-reel video slot with up to 25 free spins and an underwater fantasy theme that pairs well with the bonus spins you receive. See the slot review for details and payout features.

Payments, supported currencies, and player support

Supported methods include AstroPay Card, Bank Transfer, CASHlib, Flexepin, MasterCard, Mifinity, Neosurf, and Visa.
