If you're looking for the best RTP slots to play this weekend, games with the highest payout percentages are the obvious starting point. Volatility and max win also factor into my rankings of the top high-paying slots in the U.S. right now. The games I'll cover are available in 2–4 states with licensed online casinos, including Michigan, New Jersey, Pennsylvania, and West Virginia. Get started now with 1,000 Flex Spins when you sign up at DraftKings Casino:

The following five online slots have the best RTP I've come across during recent research involving real money online casino operators. Each game's max win and volatility are also discussed to help you line up slots that meet your preferences.

Currently exclusive to BetMGM in the U.S., Book of 99 is king among high-payback slots with 99% RTP. Its 5,000x max win is large enough for most players who value chasing big payouts.

The drawback is that Book of 99 is a basic "book-of" slot, including a 5-reel, 10-payline setup and free spins with expanding symbols. Assuming you don't mind run-of-the-mill mechanics and features, this game is definitely worth playing for the outstanding RTP.

Golden Chief is a strange case because its RTP can be 94.12% (bets under $2), 96.02% (wagers over $2), or 98.14% (Big Bet mode). You enter Big Bet mode by wagering at least $20, giving you five spins with increased payouts and double-height scatter symbols.

This game works best if you like bonus buy options and stellar RTP. The downside is that wagering $4 per spin to unlock 98.14% payback isn't for everybody. Claim 1,000 Flex Spins when you click here and wager $5 or more:

One of the all-time classics at Hard Rock Bet, Blood Suckers combines 98% payback with a 45% hit rate. The high hit frequency means you'll win more consistently with this slot than even blackjack (42.22% win rate).

The catch is that Blood Suckers' win potential is rather low at 1,014x. This game is certainly for the crowd valuing lower volatility and regular wins versus life-changing payouts.

Starmania has a rare all-ways-pays mechanic, where wins can start on the leftmost or rightmost reel. It's also one of the highest RTP slot games at Fanatics, with 97.86% RTP.

The drawback is that the max win is only 500x. Check our best paying slots guide if you're looking for bigger win potential, such as San Quentin xWays (150,000x) and Lil' Devil (100,504x). Get 1,000 bonus spins and start playing these online slots at Fanatics Casino:

Achieving Medusa Megaways' 97.63% optimal RTP requires using the bonus buy option (100x cost). The bonus buy might be tempting, considering the free spins round has an unlimited multiplier and 50,000x win potential.

However, spending 100x a standard bet isn't for the faint of heart. Even if you don't go for the feature buy and 97.63%, this game still has a respectable 96.28% base RTP among Megaways slots. Use bonus code SLINELAUNCH to get a 100% deposit match and a $10 sign-up credit at Caesars Palace Online Casino:

Choosing slots with high published payback figures helps you win back a large percentage of wagers over time. However, it doesn't guarantee anything in the short run.

Most online slots are volatile and pay inconsistently over small sample sizes. Even a game with 98% or 99% RTP can pay poorly during a single session. That's because RTP normally accounts for millions of spins. 

Again, high payout percentages are useful for long-term strategy. But volatility is also important because it dictates how consistently games pay during shorter periods.

This weekend, I'm starting my slots play at BetMGM because it's the only spot I've found Book of 99. I like this game's 5,000x win potential and moderate volatility in addition to the incredibly high RTP. Just use promo code SPORTSLINECAS to get up to 1,000 bonus spins and more rewards when you sign up:

Whether you follow my lead and pick Book of 99 or choose a different casino app and high RTP slot, make sure you're 21+ and physically present in MI, NJ, PA, or WV. If you or anybody you know struggles with problem gambling, contact 1-800-GAMBLER or 1-800-MY-RESET (National Council on Problem Gambling) for help.

Our editorial recommendations on the best RTP slots are based on research involving payout percentages, volatility, and max wins. They are independent of commercial relationships between SportsLine and casino operators.
