If someone asked you what makes a perfect slot what would your answer be? If you ask our experts from the USA, we’d say it’s both in the visual aesthetics with shiny and colorful symbols and in gameplay features with fascinating sound effects and exciting game mechanics.

Ainsworth is one of the best slot game developers out there, and that’s not just our impression. They’ve been doing it for a while now, as they have created award-winning gaming cabinets for Las Vegas and Atlantic City casinos.
You can clearly see that they put their hearts and souls into online casino games, and that led to some of the biggest blockbuster adaptations among AGT’s releases. In our opinion, it’s the jackpot prizes and exciting features that make their games a must-try for players.
Plus, it’s a brand with the official UK Gambling Commission license that makes it a trusted provider in the UK market, as well as the Alderney Gambling Control Commission license. So, they are as legit as slot providers get. At FreeSlots99, you can play free no download slots from the provider, and we’ll also tell you what to look for in the wide selection of 150+ releases available on our platform.

If you’re wondering when Ainsworth started as a brand, it all happened back in 1995. That’s when the Australian company was established by Len Ainsworth, and the first steps were made in 2001 with the initial batch of gaming machines. The way we see it, their advancement was slow but steady, considering that 2007 was the year when it all went viral.
Video slots from this provider have finally reached the big scene at that time, fueling players’ passion in Vegas casinos and gambling venues from Australia to New Zealand and all around the world. However, their casino games only went online in the late 2010s and in 2020 with the release of their A-STAR cabinets, so that’s when we finally got to witness all their glory on online casino sites.
As a major contender in the US gaming market, this software developer received quite a few awards over the years. One of the most prestigious was the ICE award for contributions to game development in the industry, and we can clearly see why they got it.
Most AGT releases feature innovative mechanics with captivating graphics and sound effects, as well as very engaging features. So, it’s no wonder they got all those awards as a testament to their contribution to innovation and advancements in the field. Along with ICE awards, the brand also got recognized as one of the top brands for high rollers, considering that some of its classics like Super Charged 7s earned a place among the top 25 High Denom releases in 2021.
As mentioned, you couldn’t really play online slot games from this provider on your mobile until recently, which was a great shame for online casinos. Luckily, the provider quickly realized the high demand and decided to once again change its approach and turn a bit of its focus on the iGaming field.
We were thrilled to learn about these a couple of years ago, and now we already have more than 150 of AGT’s finest releases, popular from Australia to the USA, all ready for you to try in demo mode. We have to say that the slot games still feature the same look and feel as their land-based counterparts.
That shouldn’t be a surprise, considering that the brand simply optimized most of its casino offerings for online play. Still, we’re not saying that you’ll be missing anything due to the latest HTML5 technology and the great responsiveness of these titles on mobile devices.
When we get asked to recommend a few of AGT’s best releases to new players at online casinos, we always have to stop for a second and think things through. There have been so many iconic releases made by the brand, making our decision even more difficult. But, we’ve managed to select a few slot titles that simply stand out from the bunch.
We were initially tempted to include Wonder Wizard on our list, simply because it’s one of the slot machines that started it all, but we had to skip it to discuss Fire Wizard. Along with the Ice Wizard which is more or less the same slot game in a different setting, it’s a direct successor to Wonder Wizard, including all the good stuff of one of AGT’s original progressive jackpot titles. Besides the progressives, it also has a feature with 10 free spins that can be re-triggered for five more, together with stacked wilds and prizes up to 10x your stake.
Rumble Rumble is a slot that started it all when it comes to AGT’s Sweet Zone mechanics, which is when the wild symbol lands directly into the highlighted box on the grid. In this casino game, it leads to the spinning area expanding and the wild turns into a massive wild that covers the entire side of the grid where the Sweet Zone is located.
Rumble Rumble might be a bit demanding to hit the Sweet Zone, but the Flying Horse gives you another chance for it. Namely, if you land at least one wild symbol in the appropriate field considering that there are two Sweet Zone boxes on the screen, you get a re-spin. In case you land another one during the re-spin, the entire screen turns into a wild symbol.
Whether it’s playing free slot machines on our platform, or if you play for real money at online casinos, it still gets tough to narrow it all down to a few best releases. We had a tough time picking the best ones already, but now we wanted to give you a glimpse of top-paying AGT slot games. So, after a while of debating, our experts have hand-picked these titles.
The thing is – most of these slot games have a return rate around 94.5%, which is not that great in the modern-day online slots world. However, they have massive payout potentials going well over 1,000x of your bet, starting with Mustang Money which pays the most. You can get a max win by landing stacked Mustang Money wilds with win boosts that go from 2x to 5x.
Other releases also have innovative features, like the Jungle Monkeys which is fairly old, yet delivers excellent gameplay with stacked premiums and feature re-triggers. We simply couldn’t omit Roaming Reels which is very similar to Jungle Monkeys, only features cutting-edge graphics with the same, 200x max win per spin for a stacked screen of premiums.
Plus, Glitter Gems have combined payouts for different premium symbols, making it easier to make winning connections on fixed paylines.
In our humble opinion, having played free casino slots at FreeSlots99 for years now, we can only say that AGT makes a household name in the current iGaming industry. Sure, they were primarily focused on making land-based releases, and we respect that. But, you can’t deny the brand’s taste in visuals, sound effects and features, which easily beat those of online-only software developers.
If you’ve never tried these online casino games before, these are some of their standout features you can count on.
On top of all that, you’ll instantly recognize that signature sound of spinning areas rolling and dropping on the grid, which has now become a synonym for Vegas gaming from this provider. Some slot games feature unique combinations of free spins features and jackpots that you aren’t likely to find anywhere else.
For instance, the popular slot Golden Lion features a special box on the right-most spinning area. If you manage to hit a full-line connection containing that box, you get one of the four progressives – the Mini, the Minor, the Maxi or the Grand. Moreover, you can win jackpots multiple times in a single special feature, and that’s something we especially learned to love about AGT titles like Thunder Cash Dollar King and Sweet Chilli.
