Slots Million is committed to adding new games every week, so new content is always just around the corner, with 2018 shaping up to be an exciting year for online casino game releases.

Slots Million


Since the site switched operators in 2017, Casino-Mate is still slowly dusting off its old association as being powered exclusively by Microgaming, with the casino now hosting games from several software providers. We love Casino-Mate’s switch to becoming a multi-provider site, with the casino now offering a much more user-friendly gaming platform, with games available from leading software studios like Betsoft and Quickspin. The best thing is that despite the switch in operators, Casino-Mate continues to offer the epic $1,400 new player welcome bonus that the site is famous for, which remains one of the biggest casino sign-up bonuses of 2018.

BGO Casino has earned extra brownie points from us recently due to its commitment to stay ahead of the curve when it comes to player safety and fairness, earning it a place on our list of the best casino sites of 2018. When the UKGB introduced new advertising standards in 2017 requiring online casinos be more transparent about wagering requirements attached to bonus offers, BGO did away with wagering requirements entirely, replacing their old welcome bonus with a 50 Fair Spins offer that awards new players with 50 spins with no play-through requirements attached. This was a novel move, which we hope to see inspiring more online casino vendors. In addition, BGO also offers a huge selection of online casino games from Playtech, NetEnt and other leading casino studios, under the watchful eye of the faithful BGO masco, Verne Troyer (AKA Austin Powers’ Mini Me).
