Below, you can learn more about the popular variations of slot games and will quickly be able to get started spinning for some great payouts.
- Traditional/Classic Slots – These are the most basic of all slot games at an online casino. With these Vegas-style slots, you’ll have three reels of action. The games typically support between 1 and 5 paylines, making them affordable. There are not too many added features with traditional slots, and the themes are rather basic. You may find games with a wild or a re-spin bonus feature.
- Video Slots – Thee are the most popular games, and they offer attractive themes, enhanced graphics and bonus features. With video slots, you will be betting on 9 to 100 paylines. Some games also offer ways to win structures, which can offer 243 or 1024 ways to win. The highlights of these games come from offering multiple bonus features, including free spins and second-screen bonuses.
- Progressive Slots – These are the top-paying games that draw the attention of many players. Progressive games can be either three or five-reel titles. These games often require a maximum bet to be eligible for jackpot payouts.
- Random Progressive Slots – Similar to progressive games, these can offer a payout without a maximum bet. One of the benefits of these games is that you can win a jackpot payout after any spin on the game, no matter what you have wagered. Random progressive games are video slots, and they offer some super themes.
