Loosest Slots USA | Best Paying Slot Machines Online

Here you can find an updated list of the loosest slots in the U.S.A. Not all slots providers publish payout percentages for individual slot machines. On the list below you can find only slots that offer official payout rates.

Cosmic Quest Slot

RTP: 98.5% Rival

Cosmic Quest Mystery Planets is the first on our list of loosest slots available online. It is a 5 reel, 20 lines game. The minimum bet is 0.01 per spin and goes up to $50. The reason for the high payout is because of the free spins feature and the expanding wilds. If you land three or more Jackpot Jetpack icons you will get 10, 25 or 50 free spins. All free spins wins are doubled.

The best casinos to play Cosmic Quest slot are Slots Capital and Cafe Casino.

Rock On! Slot

RTP: 98% Rival

Rock On Slot is an edgy rock themed game, part of the popular i-Slots series. Here you can also find expanding wilds, a free spins feature and a special Guitar Hero style bonus game. This slot is relatively simple to play, especially in comparison to Cosmic Quest.

The best casinos to play Cosmic Quest slot are Slots Capital and Cafe Casino.

Good Girl Bad Girl Slot

RTP: 97.8% BetSoft

This is one of the best online slots of all time (at least in our opinion). What is special about Good Girl Bad Girl slot is that you can control the volatility of the game. Choose the good mode and you have more frequent payouts of lower nature. Choose the bad mode and you get a high volatility slot with less payouts, but higher chances to win big. Very Cool!

You can try this slot now with  200% up to $1,000 bonus at Slots LV casino. Here you can find the Slots LV Review.

Doo-Wop Daddy-O Slot

RTP: 97.8% Rival Software

Doo-Wop Daddy-O is a simple and playful slot machine. There are two bonus games features, however the secret to the high payout is during the regular play. The minimum bet is $0.01 per spin and goes up to $20.

You can try this slot with a $10 no-deposit bonus at Cafe Casino.

At the Copa Slot

RTP: 97.5%

After Night Falls Slot

RTP: 97.2%

This is another BetSoft slot with multiple bonus features. The payouts of After Night Falls slot are a bit less frequent than At the Copa, but the max jackpot is much higher: 1,550,000 coins or $155,000! The bonus features include collapsing wilds, random multipliers, click me bonus and more.

Safari Sam Slot

RTP: 97.2% BetSoft

This is a safari themed 5 reels slot. There are various bonus rounds and features (some might say a bit too many). The maximum jackpot is lower than other BetSoft slots on this list. It stands at 250,000 coins. However the coin value is $1 (vs the common $0.1), therefore the maximum win can be worth $250,000!

The best casinos to play Safari Sam slot are Slots LV and Cafe casino. If you wish to play it on mobile then check our Slots LV mobile casino review.

WhoSpunIt Slot Machine

RTP: 97.2% BetSoft

Even without the nice RTP, this is one slot machine that you just have to try. We can’t explain exactly why, maybe it’s the time limited levels, or the intriguing murder mystery theme. You will have to see for yourself.

USA Online Slots Providers – In Few Words

RTG

RTG is by far the most popular slots developer on the U.S. market. However, it’s due to smart management and being in the right place at the right time, not the quality of their slots. RTG was in the perfect place to take the market by storm when Microgaming and Playtech pulled out in 2006. In 2011, VegasTech left and they became a real monopoly.

Since then Rival has gained more ground, BetSoft entered the market and VegasTech returned under a new name (WGS), but RTG is still the market leader with the most players.

If we had to describe RTG slots in few words, we would say their main focus is classic 5 reel video slots. Recently, they added 6 reel and 3D slots, but 5 reels are still their bread and butter.

Pros

Cons

  • Simple
  • Classic look and sounds
  • Offer more slots than any of their competitors, over 200 machines
  • Recently left their comfort zone and started launching different and innovative games
  • Not enough diversity
  • Do not post official data on the payouts
  • Most slots are pretty tight
  • Many progressive slots, which are impossible to hit. If you want to play RTG Mega progressive slots, the place to do that is Bovada Casinos: Slots LV and Ignition casino. The games here are connected to the RTG chain progressive network and actually paid a few 7 digit jackpots.

Rival

The second biggest provider on the market, Rival is the opposite to RTG. They offer superb slots, with high payouts and medium/high volatility. This is the perfect combination to generate nice winnings. However, in terms of management they weren’t aggressive enough and suffered from a poor choice of operators.

That has changed and currently there are plenty of reputable Rival casinos for US players to choose from.

Pros

Cons

  • Offer superb variety of slots
  • Post official RTP – not for every slot, but for most of them
  • High payouts + high volatility
  • Rivals trademark i-Slots
  • There are still many tiny Rival brands which can be risky and should be avoided. Stick only to known and reputable brands with a long history of operation.

WGS

WGS came to life after VegasTech shut down. The games were sold and relaunched under the new name, Wager Gaming Technology. So far, WGS hasn’t managed to recreate the success of its predecessor. There are only a few casinos that offer the software. And unfortunately, not many new games were launched in the past few years.

WGS are definitely not the leaders when it comes to innovation, but they do know how to produce nice video slots. The highlights are their 7-reel slots and the superb Slots Tournaments, which attract thousands of players.

Pros

Cons

  • Nice 5 reel video slots plus unique 7 reels
  • Frequent $$$ slot tournaments
  • Launch only 2-3 new slots per year
  • Not offered by many casinos
  • Not very creative when it comes to design, layout and features

BetSoft

BetSoft is an extremely popular game supplier worldwide, which recently (2012-2013) entered the U.S. market. The company is ranked as the #1 3D slots provider. Their games feature extensive graphics, animations, video effects and sounds.

BetSoft is either you love it or you hate it. Some enjoy the arcade look and various bonus features (some slots offer 6 different bonuses). Others hate the slow game play with too many interventions.

Pros

Cons

  • Highest average RTP on the market
  • Amazing visual effects
  • Stacked with various bonus features
  • Not for classic slots fans: many stops, pauses, & videos which might get annoying after some time
  • Not offered by many casinos
  • Do not offer official RTP stats
