A lower house edge means you lose less on average over time. No game can be beaten in the long run, so set a budget before you play.

Types of online casino games

Slots

The biggest category by far. Classic 3-reel slots keep things simple, video slots add bonus rounds and free spins, and Megaways games change the number of ways to win on every spin. Explore classic slots and video slots.

Table games

Blackjack, roulette, baccarat and poker variants, played against software. These usually carry the lowest house edges in the casino, especially blackjack played with basic strategy.

Live dealer games

Real dealers streamed from a studio, with blackjack, roulette, baccarat and game shows. Live tables play at real stakes only, not in demo mode.

Crash and instant games

Games like Aviator and Lucky Jet, where a multiplier rises until it crashes and you cash out before it does. Read our Lucky Jet guide.

Tips before you play for real

  • Check the RTP in the game’s info screen. It can differ between casinos for the same slot.
  • Pick European roulette over American, and blackjack tables that pay 3:2.
  • Read the bonus terms, including which games count towards wagering.
  • Set a deposit limit and never chase losses. Check your local laws before you play.
