Slot Machine Variants
Once upon a time slot machines were simple one-armed bandits. All you had to do to win a real money prize was pull a lever and matching up three symbols on a reel. Times have changed.
Now there are exciting video slots, themes from your favourite superhero movies and so much more. Here’s a rundown of the most common slots you’ll run into.
Classic 3-Reel Slots
- The most famous and widespread real money online slots games are 3-reel machines, which are also coincidentally the simplest to get started with.
- This style of slot hails back to where offline slots machines all began but you can play these 3-reel online slots for real money more or less anywhere online.
- Winning is straightforward. Just match three symbols across a single payline.
Multi-Reel, Multi Payline, Video Slots
- As online slots became more developed, game designers started increasing the number of reels and paylines.
- It’s now common to find machines with over 100 paylines and 5 reels.
- These online video slots also typically offer fun bonus games and more interactive gameplay as part of their design.
Progressive Jackpot Slots
- Progressive jackpot slots feature a special prize that’s usually won in a bonus round. The jackpot keeps getting bigger until someone wins it, then it resets.
- The most famous progressive jackpot slots in 2020 include Mega Moolah, Arabian Nights, and Mega Fortune. These slots have jackpots that frequently roll into millions of dollars.
- A small part from each bet goes into the jackpot, which is why these slots have slightly worse odds than the non-jackpot versions.
Software Developers: The Power Behind the Gameplay

Online Slots Tips and Strategies
- To get the best odds, look for games with the highest RTP (Return to Player). RTP refers to the amount of money that’s paid out in winnings, on average, for every $100 you bet. The best slots have RTPs in the high 90s.
- Don’t be afraid to try multiple slots sites. You might find new games you like and you’ll also get a valuable signup bonus each time you sign up for a new account and make your first deposit.
- Play progressive jackpot machines if you want to take a shot at a life-changing payday. The odds are longer but the jackpots get into the multiple millions of dollars. Check our reviews for sites with the best progressive jackpot slots.
- If you want to play conservatively and go for smaller wins, play machines that have a higher payout frequency. These are sometimes called “loose” slots because they pay out smaller prizes more often.
- Always stay within your bankroll. Choose an amount of money that you’re comfortable playing with and decide how long it should last you. The most important part is to stick to your plan, even if you get unlucky in the short term.
