What Online Slot Machines Have the Highest RTP?

You should stick to high RTP slots online if you want to enjoy slot machines without giving the casino too much of an edge. The best games you can find usually return over 97% to the players, compared to around 95-6% on average. That makes a huge difference in the long run!

In this guide, I break down the five highest RTP online slots available to US players. I explore their features and let you know where to find them! Let’s start with a quick overview.

Best RTP Slots Online: Summary

The following titles are the best RTP slots online we could find:

Clash of Queens

Clash of Queens is a fairytale-themed slot from Qora Games with a reported RTP of 98.00%. It uses up to 25 adjustable lines and allows bets as low as $0.01 per line. You can bet up to $4 per line, for a total of $100 per spin.

The titular Clash of Queens logo serves as the scatter in the base game. Scatters can pay in any position, and you only need two or more scatters to win a prize. Clash of Queens also includes a wild symbol that can substitute for any standard symbol and appears on any of the final four reels in this 5×3 slot game.

The two queens, the Red Queen and the White Queen, trigger the bonus features in Clash of Queens. If they appear at the same time, they activate the Battle Feature. You must select a Queen to back, and if she wins, you trigger their bonus round.

When the Red Queen wins, you automatically get four free spins. If you correctly picked her to win, you get an additional four spins, for a total of eight free spins.

The White Queen, on the other hand, triggers a pick-style bonus round. If you selected her to win, you get a 2x multiplier for her bonus round. During the feature, you reveal prizes until you turn over a “Collect” symbol, and then all the prizes you revealed are awarded to you.

Red Dog Casino offers both free and real money versions of Clash of Queens to its members. If you create a new account, you can use the site’s welcome bonus to get up to $8,000 in bonus funds with your first deposit.

Wynloch Keep

Wynloch Keep is another excellent slot for players hoping to maximize their RTP. The game comes with an RTP of 98.00% and a maximum win of 3,000x your stake. It uses five reels and 15 fixed pay lines in the base game.

There are four jackpots available in Wynloch Keep:

• Mini jackpot = 25x stake
• Minor jackpot = 50x stake
• Major jackpot = 250x stake
• Grand jackpot = 2,500x stake

To win a jackpot, you first need to trigger the Treasure of the Keep bonus round. This Hold & Win mini-game is activated when five or more Treasure Coin scatters appear on the same spin. You will have three free spins to collect Treasure Coins, and each coin collected adds to your spin total.

Wynloch Keep also has a bonus round called the Tower of Power. During this round, two of the five reels are randomly selected to become wild. They stay wild for your respins, and any additional wilds that appear are locked in place.

The respins feature also adds additional rows and paylines to the grid. It can grow from 5×3 to up to 5×6.

Bovada has a free demo of Wynloch Keep available to all members. Or you can jump right into the real money version and use the $3,750 crypto welcome bonus to grow your slots bankroll.
