What to check before playing at a Relax Gaming casino
The slot's RTP version
Many Relax Gaming slots exist in several RTP versions — 96.5%, 94.5%, sometimes as low as 88%. The casino chooses which version it deploys. Check the RTP shown in the game's info panel before starting a session.
Games excluded from wagering
On casinos with an active bonus, several Relax Gaming slots are sometimes excluded from wagering (usually the hits with the highest win caps). Read the list of excluded games in the T&Cs before betting during a wagering period.
Provider availability by region
Some casinos restrict Relax Gaming for players in certain jurisdictions (a restriction set by the provider itself). Check availability on your account before counting on a specific game — WinKingdom and Atlantis Slots, for example, apply adjusted provider lists depending on where you play.
