Online casinos offer a number of high roller casino games. Most people think of table games as the only ones which have high betting limits but now you can play high roller slot machines with single bets up to 250 per spin. Of course these games offer high payouts when you hit either bonus rounds, spins or hit a combination on the reels. Above is a number of high roller online casinos which do have high limit games, we recommend Royal Vegas as one of the best which gives players excellent high roller bonuses. If you join the casino in a mobile version the betting limits may be smaller than the download software. This purely depends on the casino and what they have set for max bets on mobile. You may contact support and ask to have those wagering limits raised.
