The Best Slot Machines To Play In 2023

Online slots are the most popular online casino game nowadays. These games draw inspiration from classic slot machines at Las Vegas casinos, but they are made differently online. More bonus games, better odds, crisp graphics, and huge variety.

Finding a top-notch online slot machine across all main areas – gameplay, RTP, payouts, odds, sound effects, theme, etc. – is near impossible. Some slot machines are the best in terms of odds, but others offer a distinctive experience because they combine mini-games with progressive jackpots and free spins.

In this guide, we will try to do the impossible. Provide you with excellent slot machine names based on all critical factors. Our experts have tried out thousands of games to come up with the following names of slot machines!

The word best is personal in most cases. My top-rated online slots might be unappealing to you. However, there are some objective areas where you can focus when searching for an excellent slot machine to play at a casino. Here they are:

Odds

Slot machines with the best odds carry good long-term winning chances. This can be defined based on a game’s return to player rate, which is a theoretical value that plays out across millions of spins. The higher the slot RTP, the better its odds of winning more.

Bonus Games

Traditional slot machines in Vegas and Atlantic City featured 3-reels or 5-reels at best. This limited the creativity and bonuses that could be added to the games. As such, most games carried wilds, scatters, and a free spin feature. Online slots are way more interesting when it comes to their bonuses. Some slot machines feature expanding reels, upgraded symbols, wilds, wild multipliers, scatters, bonus symbols, jackpots, and more.

Payouts

Like RTP is used to calculate the long-term payouts; volatility is another metric you can consider when searching for the best slot machine at a casino. It ranges from low to high, with higher variance games signifying big win slot machines but less frequent wins. This can significantly affect your gaming experience and bankroll.

Gaming Vendor

The slot options you get online are different for land-based slot machines because different companies make them. Online slot machines are more diverse, with over 200 software companies producing them. In contrast, a handful of gaming vendors make slot machines for Vegas casinos. Knowing who makes the game can help you find the slot machine names you will see at selected casinos.

These areas help us spot top-rated games across several benchmarks objectively. The same cannot be said for gameplay since one might prefer classic slots and someone else Megaways slots. Using these criteria, we explain which slot machines are the best from each category.

Icon Best Slots To Play in Vegas

The best Las Vegas casinos are home to 2,000+ slot machines. Most of these Vegas slots are powered by IGT, Light & Wonder, Aristocrat, Ainsworth, Bally’s Technologies, and other classic industry names. Usually, their RTPs range between 85% and 95%, which is below the industry average for online slots. This is normal, though, due to the massive costs they need to pay for the maintenance of the venues.

They stand out for their variety of themes, typical gameplay, progressive jackpots, and ‘expensive’ themes. By expensive, we mean branded slot machines, either based on movies or celebrities. You can find slot machines themed around Batman, Paris Hilton, or Robocop. But that’s not a smart way to go about finding the best slot machine to play at a land-based casino.

Instead, we suggest players the following games if they ever find themselves in a Vegas casino:

1

Book of Dead

This game is powered by Play’n GO and plays with high volatility and a 96% RTP. It made quite some noise after it was added to Las Vegas casino floors because it is distinctively modern. Great graphics and execution are of an Egyptian theme playable on a 5×3 reel game grid. The Book of Dead symbol is the game’s scatter and wild, helping you form wins and trigger 10 free spins with upgraded symbols. The maximum win in this game is an impressive 10,000x!

2

Cleopatra

The renowned Egyptian slot by IGT, still makes waves at Las Vegas casinos. The graphics and gameplay are less modern than in Book of Dead, but it remains popular because the free spins round can be retriggered up to 500 free spins. This makes the 10,000x jackpot win reachable, and many players have won it over the years.

3

Ultimate Fire Link China Street

The Ultimate Fire Link series is the US version of Hold and Win and Lightning Link slots. It’s a bonus game connected to a network jackpot that can pay out millions to the winner. The China Street slot is one of the best Ultimate Fire Link games at Vegas casinos because it plays with a 95.97% RTP, medium to high volatility, and can payout 10,000x without counting in the progressive.

Wild scatters and free spins are all there, including a 5×4 reel structure that deviates from the classic Las Vegas slots.

The free spins round lets players choose their volatility, with a selection of free spin rounds with varying multipliers. If you get four fire symbols, you’ll experience the outstanding progressive jackpot game that guarantees payouts!

Slot Machines With The Best Odds

RTP is king in slot machines. It doesn’t matter if you are looking for the best online slots for real money or the best slot machines at a casino. The higher the RTP value, the more likely you will win in the long run.

This value is theoretical and provided by the gaming vendors of slot machines. It is always negative since these games guarantee profit for the casino, but you could always bring it home before the average is realized. The higher the RTP, the better your slot machine winning chances.

As we previously mentioned, online slot machines are much better regarding RTPs. The 96% is the industry average, but you can do much better than this. To help, we list the 10 best slot machines in terms of odds:

Best odds slot machinesRTPProvider
OOH AAH Dracula99%Barcrest
Jackpot 600099%NetEnt
Marching Legions98.12%Relax Gaming
The Catfather98.1%Pragmatic Play

Golden Tour97.71%Playtech
Big Red97.04%Aristocrat

Icon Best Payout Slot Machines

Long-term payouts are different than actual online slot payouts. Most of the games we provide above are low to medium-volatility slots that offer a balanced game. Your balance will most likely average its starting point when playing such high RTP slots with low risk.

If you like your gaming experience to be fun and adrenaline-filled, you got to look elsewhere. Preferably to our list of best payout slot machines.

The slots that pay the best at the casino will either be high volatility slots (scarce but big payouts) or progressive jackpot slots. The latter is a standard slot game that includes a top progressive prize that accumulates based on all the bets placed on it or the linked network until someone wins it. The prize then resets and starts from scratch. Some progressive slot machines have paid over $40 million in one go. Still, high volatility slots these days can offer equal massive payouts without a progressive pot.

Icon Slots With Bonus Games

All slot machine types we covered in the previous sections are outstanding in terms of odds, payouts, RTPs, and overall mechanics. But not equal when it comes to bonus rounds and gameplay.

Players looking for exhilarating bonus games must look far beyond a standard free spin round or stacked wilds. Themed bonus games immerse you into the action, where you must uncover hidden treasures to win a prize or climb up ladders by selecting random buttons. They don’t necessarily pay more, but top bonus game slots can be extremely fun. Here are some excellent examples:

  • Gonzo’s Quest Megaways – one of the few slot games that have created a cult around it, the remake of the original Gonzo’s Quest has some excellent special features. First, all wins lead to a symbol cascade that enables cascading wins with increased multipliers. Wilds remain stacked through cascades and can lead to exquisite winning combos. The earthquake bonus can randomly remove all lower-paying symbols. A free spin round with cascading wins and progressive multipliers with retriggers. What else to ask from a slot?
  • Gates of Olympus – an award-winning slot by Pragmatic Play themed around the god of thunder, Zeus. No paylines. Land eight symbols or more anywhere and you get a win. Random multipliers up to 500x can appear anytime in the base game. Trigger the 15 free spins, with 5 additional free spins for three scatters, and all random multipliers remain stacked. The result? Up to 10,000x maximum win!
  • Dead or Alive 2 – sequels rarely match up the original games’ success, but this NetEnt slot is an exception. Wild multipliers keep the fun going in the Wild-West base game, but the free spins bonus brings the game to another level. You get to choose your volatility (risk), with three free spins rounds with varying multipliers, number of spins, and add-ons. Up to 111,111x maximum win and a $0.09 minimum bet. A great bonus slot game for all.

#5 Cazino Zepellin Reloaded

  • RTP – 96%
  • Max Win – 102,838x
  • Stakes – $0.10 to $1.2
  • Developer – Yggdrasil

This is a lesser known slot, but my personal favorite. It’s a super high volatility game taking place in a zeppelin where a group of gamblers plays casino games. I love this game because it can pay over $100,000 from a low max bet of $1.

This can be achieved through the multiplier wilds carried to the free spins bonus game. Any additional wild that lands add a multiplier to all other stacked wild multipliers bringing home massive wins. The bonus game can also be retriggered for even bigger wins!
