Mustang Spirit Cash Stacks slot design

Mustang Spirit Cash Stacks is designed as part of the Cash Stacks family of Ainsworth’s game series. This game is still inspired by North America’s wild horses that are known as the Mustang. Just like its first versions, the studio designed this slot to showcase the beauty of the wild Mustang that live freely in the vast grassland of America.

This slot offers multi-denomination options to players, Wild Mustangs, Cash Stacks Scatters, Boost Scatters, Bonus Spins, and much more! Don’t miss out on Ainsworth’s popular American horse-inspired slot that you can play on different online casinos. Its low-paying symbols include the common Royals: 9,10, J, Q, K, and A icons with various decorations. The Cactus, Scorpion, Wolf, Bear, and Bald Eagle are the premium symbols on the reels.

Mustang Spirit Cash Stacks features

Mustang Spirit Cash Stacks is the sequel of Ainsworth’s Mustang Spirit and Mustang Money that were released a few years ago. Developed by Ainsworth, this slot comes with 5 reels and 3 rows in the game area. Just like its predecessor, Mustang Spirit Cash Stacks has a Wild symbol and a Scatter symbol on the reels. The studio did some changes in its features but the Bonus Spins are still there so let’s see what else is new here.

Wild Symbol

Mustang Spirit Cash Stacks reused the Mustang Horse symbol as its Wild symbol. Unlike Mustang Spirit, its Mustang symbol includes a WILD logo already to make it more distinguished than the rest of the symbols. The Wild Mustang can also appear and replace all regular symbols on the reels as a common function of Wilds. However, the Wild Mustang is still not powerful enough to replace the Scatter symbol.

Scatter Symbol

If there is a Wild Mustang, there is also a Golden Coin or the Cash Stacks symbol. This special symbol functions as the first type of Scatter on the reels. The Cash Stacks Coin Scatter is the key to activating the Hold’n Stack feature. But most importantly, the Cash Stacks Coin Scatter always appears on the reels with a random prize.

Depending on your luck, the cash prizes may vary from 1, 2, 3, 5, 8, 10, 20, 25, 50, to 100. These rewards are multiplied by your total bet that is displayed during your paid games and even in the bonus feature. The winning combinations that involve the Scatter symbols can pay you regardless of their positions.

Of course, the second type of Scatter symbol is the Boost Scatter. This special symbol looks like a huge purple Bubble or Orb with a BOOST logo on it. The chances of hitting a winning cluster with a bigger reward are higher each time the Boost Scatter symbol appears. On the other hand, the Boost Scatter can appear on each reel once only.

Hold’n Stack Feature

Now that we are done with the Wild and Scatter symbols, let’s head to Mustang Spirit Cash Stacks’ bonus feature. As mentioned above, triggering this bonus feature requires the Scatter symbol. You need at least 3 or more Cash Stacks Coin Scatters to activate the Hold’n Stack feature. These Scatter symbols come with an attached random cash prize that ranges from 1 to 100.

The Hold’n Stack feature also welcomes players with 5 Bonus Spins once it is triggered. The Scatter symbols that triggered this bonus feature remain held in their positions as Sticky Scatter symbols. At the same time, these triggering Cash Stacks Coin Scatters award prizes that range from 1, 2, 3, 5, 8, 10, 20, 25, 50, to 100. These prizes are multiplied by the total credit bets and displayed awards.

Their value is multiplied by their total bet during this bonus game which is the cool thing about these symbols. This means that you can get a huge payout out of these Cash Stacks Coin Scatters on each winning combination. You will see the Cash Stacks Prize appear on top of the reels. Also, the total bet that you played during this bonus feature is similar to the game when you triggered the feature.

Cash Stacks Prize

The Scatter symbols stack for those who are lucky to land 3 Cash Stacks Coin symbols on a single reel. But the best part of stacking these Scatter symbols is getting the Cash Stacks Prize that is displayed on top of that reel. These Cash Stacks Prize are awarded a random value that ranges between 3, 5, 8, 10, 20, 25, 50, and 100. These are also multiplied by the total credits bet or displayed as the Mini, Minor, Major, and Grand Prize.

Mustang Spirit Cash Stacks RTP, betting and prizes

This Mustang Spirit Cash Stacks Slot is accessible to players with a minimum of 50 pay lines. For those who want a higher chance of forming winning clusters, the number of pay lines can be increased to 100. Each spin requires a minimum of £1 bet and a maximum of £50 on each spin. This is slightly higher than its previous version that allows players to bet up to £20 per spin only.

There is an AutoPlay button where players can select Auto Spins that range from 0, 5, 10, 15, 20, or 25. There is also a MAX button next to the Total Bet below the reels. This option allows the players to automatically set the bet into the maximum amount on each spin. Once you are ready to pay, simply click the huge green Play button on the right side of the reels.

When it comes to the returns, Mustang Spirit Cash Stacks has a 96.02% that is on the average level. Still, this RTP is higher compared with its previous versions that offer less than 95% returns and a smaller number of pay lines. Its biggest rewards await in the bonus round that offers the following jackpots:

  • Mini Jackpot = 10
  • Minor Jackpot = 50
  • Major Jackpot = 250
  • Grand Jackpot = 25,000

For regular winnings, Mustang Spirit Cash Stacks has regular symbols like the Royals. For instance, the A, K, and Q Royals pay £0.50, £2, to £7.50 for 3 to 5 symbols. The J, 10, and 9 Royals pay £0.50, £1, to £5 on each spin. For the high-paying symbols, Mustang Spirit Cash Stacks features the Wolf, Scorpion, and Cactus that pay £0.50, £2.50, and £10 matching symbols. The Bear symbol pays £0.50, £3, and £15 while the Eagle pays £1, £5, and £20 for 3 to 5 matching symbols.


Feel free to run with Mustang Spirit Cash Stacks’ wild horses in this Cash Stacks version. This slot version borrowed many of its predecessor’s paying symbols but modified the others especially the high-paying symbols. It is a good move that Ainsworth increased its number of ways to win on each spin and its return to players. Starting from below average, Mustang Spirit Cash Stacks now offers an average RTP that offers decent payouts.

It is also cool that Mustang Spirit Cash Stacks has a low stake that can suit different kinds of players. Since this is an improved version, the features are also improved to offer bigger jackpot prizes. However, this is not the game for you if you want to get plenty of Bonus Spins and more exciting features.
