SG Games has brought the land-based Coin Combo series online with Marvelous Mouse as one of its games. The base game features a wild and a scatter, with the latter in the form of random element coins that gradually fill three bowls, each triggering its own bonus feature. These bonuses include the jackpot pick feature, in which you can pick one of four jackpots, and six different types of free spins games. 

Theme, graphics & soundtrack

Coin Combo Marvelous Mouse has an Asian theme and Chinese-inspired music. The reels are decorated in red and gold, which are colours associated with Chinese New Year celebrations, and the symbols include fortune cookies, golden bowls, oranges, an ornate teapot and - of course - the Marvelous Mouse himself wearing a red and gold jacket and hat. In the background, mountains and a pagoda complete the scene.

Coin Combo Marvelous Mouse bonus features

During the base game, red, green or blue element coins gradually fill the bowls of their corresponding colour, eventually triggering one or more bowls to start the bonus feature. 

Jackpot pick feature

Triggered by the red bowl, you will be presented with a grid of 15 coins. Pick these at random to collect Fu Babies. If you pick three matching Fu Babies, you will win the corresponding jackpot: green for mini, blue for minor, pink for major and red for the grand jackpot. In addition to the 12 Fu Babies, there are three upgrade coins hidden in the grid. If you turn over all three upgrade coins and go on to win a jackpot, this jackpot will be upgraded to the next level. If you win a grand jackpot, this will be awarded twice.

Free spins

Depending on the number of bowls that trigger, you will be awarded one of six free spins games. They are:

Blue = 6 free spins on 4 rows (mighty)
Green = 6 free spins on 5 rows (mega)
Blue + green = 6 free spins on 6 rows (super)
Blue + red = 6 free spins on 4 rows + jackpot pick (ultra)
Green + red = 6 free spins on 5 rows + jackpot pick (supreme)
Blue + green + red = 6 free spins on 6 rows + jackpot pick (ultimate)

During the free spins games, element coins may land to award +1 or +2 free spins or cash prizes. In the ultra, supreme and ultimate free spins, element coins may also award the mini or minor jackpots.

Coin Combo Marvelous Mouse review: our verdict

Anyone who has played and enjoyed SG Gaming's Dancing Drums and 88 Fortunes, which you can find on our SG Gaming slots page, will instantly recognise the bowls, jackpots and Fu Babies that form an integral part of the bonus features on Marvelous Mouse. To the uninitiated, this is a beautiful looking game with a complex bonus system that is interactive, satisfying and can be rewarding, especially if a combination bonus is triggered. If you find Marvelous Mouse too elaborate and simplicity is what you prefer, PG Soft's Fortune Mouse slot with its single bonus spins feature and 3x3 layout has a similar charm and theme. If you are looking for 243 ways to win with a different theme, we have over 300 243 ways to win slots to choose from.
