Assassin Moon Review

Assassin Moon is a game developed specifically for Microgaming by Triple Edge Studios. It follows Luna, a gorgeous but deadly hitman (or hitwoman) on a dangerous assignment in Monte Carlo. Luna appears as the Wild symbol on the reels, either as a single symbol or in stacks of two or three. She is also the highest paying symbol on the reels, with 5 of a kind earning 12 500x your line bet.

Assassin Moon is the first online slot to be produced under Microgaming’s HyperHold brand, a collection of slots that include the ever-popular Hold and Spin concept that has been a huge hit in land-based casinos. Stacked Wilds, a free spins bonus with enormous 3×3 symbols on the centre reels, and a Win Booster that boosts your chances of triggering the HyperHold bonus are some of the other features.

For as little as C$0.10 per spin, you can play Assassin Moon on your desktop, laptop, or mobile device.

Assassin Moon Game Features


On the reels, look for the rare HyperHold Moon symbols. The HyperHold Bonus is triggered when 6 or more HyperHold symbols appear on the screen, giving players the chance to win cash prizes and one of four fixed jackpots. All triggering HyperHold symbols remain in place on the reels during the feature, which begins with three free respins. Any further HyperHold symbols that land are similarly locked in place, and the respins counter is reset to 3 for each symbol slot that is not occupied by a HyperHold symbol.

All cash values revealed on the bonus symbols are totalled up and awarded to the player at the end of the feature. If their corresponding symbols land on the reels, the Mini, Minor, and Major Jackpots are awarded. If all 15 reel positions are filled with HyperHold symbols, the Mega Jackpot is given.

The payout values of the 4 jackpots are:

  • Mega Jackpot – 5000x total bet
  • Major Jackpot – 750x total bet
  • Minor Jackpot – 150x total bet
  • Mini Jackpot – 50x total bet

The HyperHold feature can be triggered in the Base Game and in Free Spins.


Free Spins

Free Spins Scatters appear on reels 2, 3 and 4 in the Base Game. If you get three or more Scatters, you’ll get ten free spins. The middle three reels merge to form huge 3×3 symbols known as Jumbo Blocks during the Free Spins Bonus. If you land a Scatter Jumbo Block, you’ll get an extra 10 Free Spins. During Free Spins, the HyperHold function can be used.

Win Booster

The Win Booster button increases the player’s chances of triggering the HyperHold feature by adding extra HyperHold bonus symbols to the reels. When the Win Booster is turned on, the entire stake is multiplied by 2.5.

The Assassin Moon 200 Spins Experience

We were immediately pleased by the overall design and quality of the artwork when we first joined the game. The characters, symbols, and background drawings clearly took a lot of time and effort to create. We were ready to spin after checking out the paytable and setting our wager to C$3.75. The Luna Stacked Wilds on reels 1, 2 and 4 generated a 20x Big Win on spin 23. We hit three Free Spins Scatters on reels 2, 3, and 4 later in the game, triggering the Free Spins Bonus.

As the day gave way to night, our attention was drawn to the centre three reels, which exclusively exhibited huge 3×3 symbols during the Free Spins Bonus.

Our free spins adventure reached new heights when we landed a massive HyperHold bonus symbol on the centre reels, indicating that we had triggered the HyperHold Bonus within free spins… oh yes! We got C$33.75 in cash rewards from the HyperHold Bonus, but no jackpots were awarded. Returning to the Free Spins Bonus, the remaining free spins were played out. Our total free spins and HyperHold wins came to C$68.25, or about 18x our C$3.75 total stake. Assassin Moon is a fantastic-looking game that also plays well. We couldn’t help but notice a connection between Luna and Jane’s vocal prompts after recently playing Microgaming’s Agent Jane Blonde. Is it possible that the voice actor is the same?


Review Summary

Assassin Moon slot game is well-designed and well-thought-out. Microgaming hasn’t released many Hold and Spin games before now, and Assassin Moon does not disappoint. Triple Edge’s game designers have created a sleek and engaging game that will appeal to a wide range of slot gamers, with two outstanding features and a maximum win potential of 12500x.

“First stop, Monte Carlo,” Luna says as the game loads, leading us to suspect that this could be the first of a series of Assassin Moon games. If that’s the case, we’re excited to accompany our seductive heroine on her next action-packed adventure.
