Greentube games and what they play like
Book of Ra Deluxe 10 has a 1,500× maximum win in our review. Book-style slots like it rely on a free spins feature with an expanding symbol, so most of the return comes in that feature and the base game can run quiet for long stretches.
RTP: what to check
Our review lists 95.02%. That is about one point below a 96% slot, which over a long session means about €1 more lost on average for every €100 wagered. Some studios supply the same slot in more than one RTP setting and the casino chooses which to run, so open the game's info or paytable screen to see the RTP you are playing. Our guide to how slots pay explains RTP and volatility.
