Prosperity Mouse

Prosperity Mouse Review

Prosperity Mouse is a charming 3-reeler slot developed by the Maltese software developer Rectangle Games. It was launched in the second half of 2026 as part of the provider’s Prosperity series. The game is fast, straightforward, and is packed with one or two features. It also comes with a high RTP rate, balanced volatility, and a decent payout capacity given the complexity.

Rectangle Games is registered in San Giljan, Malta and was founded in 2024. The company managed to launch around 50 online slots for slightly more than a year and several instant-win games. According to its website, Rectangle Games is certified by Gaming Associates and BMM Testlabs for the fairness of game results. The studio started its Prosperity series in 2025 and quickly extended it.

Like with other slot providers emphasizing luck and fortune, the studio includes several animals in the series. An Ox, Dragon, Dragon Golden Reel, Tiger, Rabbit, and obviously, a Mouse. Each of these titles stands out with simple gameplay yet is quite efficient for those looking for this particular type of gambling entertainment. I’m not certain how to classify Prosperity Clash, as it’s not a slot, so I leave this one to you!

Prosperity Mouse has a beautifully designed 3x3 grid and offers 5 lines, paying from left to right. A Symbols Collection mechanic is in place, as the character on top of the reels will collect all non-winning wild symbols. This small portrait-style slot is packed with all the technical features you might need: Autoplay, Turbo, Super Turbo, etc. Test them along with the game itself via the Prosperity Mouse demo link above.

Prosperity Mouse pays for 3 of a kind, and the wild symbol is the highest-valued one in the paytable. It substitutes for all the others, and if lined up, it pays 60x the bet. Moreover, wilds often land in stacks, increasing the Hit Frequency rate significantly. Gold Ingots pay 20x, Pots of Gold - 10x, Counting Frames - 6x, while Fans, Green Circles, and Coins award 3x, 1x, and 0.60x the stake, respectively.

Prosperity Mouse is designed to fit the gambling preferences of a wide group of gamblers. The betting range provides 20 stake levels and stretches from €0.10 to €200 per spin. Keep in mind that some online casino operators may limit the max wager to lower values. If not, you can benefit from the high payout rate and multiple betting options to implement a strategy.

The Prosperity Mouse RTP ranges, and Rectangle Games has officially stated 2 rates in its game presentation - 97.02% and 96.99%. I also found 96.36% while doing my research! All 3 rates seem impressively high, especially given the slot’s medium levels of volatility. Still, you should be careful of other versions with not so lavish RTPs. The Prosperity Mouse max win is 1,000x the bet for covering the whole grid with wild symbols.

Prosperity Mouse Features

Prosperity Mouse offers fast-paced gameplay with frequent wins and stacked wilds. Yes, but there are very few bonus features in the pack. Actually, there is only one and it triggers randomly. This explains the lack of ante bets and bonus buys. The title remains a light-hearted online slot with all the advantages and flows of the genre!

Prosperity Mouse Feature

As I already mentioned, the wild symbols that did not participate in winning combinations are collected by the character above the reels. Thus, they contribute to the Prosperity Mouse feature and may trigger it randomly. The animation effects are for aesthetic purposes only! When the feature kicks in, it will add a wild stack on the middle reel and will respin reels 1 and 3 until a winning combination is formed.

Theme & Graphics

Prosperity Mouse shows off with a marvelous design in a mobile-friendly style, as I already pointed out. The red grid with gold decorations, pink blooms on top of the reels, and pagoda buildings in the back suggest an Asian theme. All that perfectly fits the vibes of joy, festivity, and fortune. If you like that kind of atmosphere, you will also appreciate the light-hearted, traditional audio effects.

Prosperity Mouse spins fast and delivers eye-catching visuals with every win or wild symbol collection. It is designed to entice mostly players on the go, although the game is also compatible with desktop devices. As I tested it in both, I must admit that some adjustments might be challenging if you use a smartphone with a smaller display.

Pros And Cons Of Prosperity Mouse Slot

Our Verdict

Prosperity Mouse is a fun and easy online slot that copies more or less the 2020 Fortune Mouse by PG Soft. This is another proof of possible cooperation between the two mobile-first game developers. In addition to the design similarities, both titles share close to identical volatility, RTPs, features, and layouts. Still, the one by RG is more polished and looks better given the 5-year production gap.

If we ignore the clone moment, Prosperity Mouse stands well audibly, visually, and technically. It has a decent payout potential, pays frequently enough to keep my attention, and offers easy to comprehend features. Well, one bonus feature, not many, I might prefer more action-packed releases like Lucky Panda and Shapes of Fortune by the same provider.

If you wish to compare Rectangle Games’ approach, I can suggest trying Lucky Mouse. The title released by Fat Panda in 2025 comes with a 3-4-3 grid, 10 paylines, and a win cap of 1,000x. It is a highly volatile slot with an RTP of 96.57% and offers random wilds, stacked wilds, and multiplier wilds. All in all, Prosperity Mouse falls in a category where competition is severe. Many players prefer to relax with slots like this one, and this title in particular hides plenty of value!
