Here’s everything you need to know about this new online sweepstakes for slots players, and some tips on how to get the most out of the Coin Combo bonus promotion.

How the Coin Combo Slot Bonus Features Work

Above the reels of all Coin Combo slot games are three element bowls: red, blue, and green. As the player spins, they can reveal corresponding coins, which will go into the element bowls and potentially trigger one of seven different bonus features.

If the player triggers the blue or green bowls, they trigger Free Spins or an automatic prize of x100 the total bet. During Free Spins, players either get extra rows or extra wilds, plus special symbols that add to the win total or increase the number of free spins.

If the player triggers the red element bowl, they win the JACKPOT PICK bonus feature, which is universal across all Coin Combo games.

Coin Combo Jackpot Bonus

When a coin lands in a red element bowl, the player could trigger the JACKPOT PICK bonus feature. Here’s how it works:

  • Players click 15 coins to reveal hidden symbols.
  • Reveal 3 upgrade symbols to increase the jackpot. If you triggered the Grand Jackpot right off the bat, 3 upgrade symbols mean you win TWO Grand Jackpots.
  • Reveal 3 Fu Baby symbols to win the jackpot.

The feature ends when the player walks away with a jackpot prize. So if you trigger the JACKPOT PICK bonus feature on the Coin Combo slot game, you know you’re walking away a winner.

Does the Number of Coins Matter?

Getting a matching element bowl coin doesn’t guarantee a bonus feature trigger, and the number of coins accrued does not increase the likelihood of a bonus feature. However, this isn’t necessarily a bad thing, because the first matching coin could trigger the bonus feature just as easily as the tenth.

Why Are Coin Combo Slot Games So Popular?

Unlike most slots with bonus features, Coin Combo slot games offer players the chance to win both the jackpot and the free spins feature simultaneously. That means players can experience the JACKPOT PICK bonus and win even more with the boosted Free Spins, all during the same round.

The possibility of that kind of huge payout is too much to resist. Putting aside the striking graphics, smooth animations, and unique symbols, that alone is enough to make Coin Combo games a must-try for players.

As an Asian-themed slot series, lucky symbols of ancient origins can make many players feel that they have an edge over non-Asian-themed slots. And they may well be right.

About Each Coin Combo Slot Game

1. Marvelous Mouse Coin Combo

Play For Real at BetMGM Casino

  • RTP: 96%
  • Volatility: Medium
  • Up to 7776 ways to win
  • $250,000 max win
  • Special Features: x100 bet feature; Extra reels during free spins for 7,776 ways to win

Marvelous Mouse Coin Combo is the most popular of the Coin Combo slot games for a few different reasons. For one, the Marvelous Mouse slot is the most commonly found Coin Combo machine in brick-and-mortar casinos, so players stay on the lookout for it. The bonus feature can also trigger up to 7,776 ways to win on every spin. And, unique to Marvelous Mouse, blue and green element bowls could trigger x100 total bet instead of the Free Spins, instantly giving players a big payout.

2. Hurricane Horse Coin Combo

Play For Real at BetMGM Casino

  • RTP: 96%
  • Volatility: Low
  • 243 ways to win
  • $250,000 max win
  • Special Features: Extra wilds during free spins; Persistent wilds; Red mystery envelope

Rather than extra rows, Hurricane Horse Coin Combo adds up to 12 extra wilds to the reels during the Free Spins bonus feature. Plus, this game boasts a persistent wild symbol, which moves up one reel position for each subsequent spin. And if the wild lands on an element coin, it becomes both a wild and an element coin.

Also, unlike Marvelous Mouse, this Coin Combo theme also offers a RED MYSTERY ENVELOPE bonus, which is triggered at random and contains a mystery cash prize. So, while Marvelous Mouse is certainly the most popular, Hurricane Horse Coin Combo holds a place in any discerning slot player’s rotation.

3. Carnival Cow Coin Combo

Play For Real at BetMGM Casino

  • RTP: 95.97%
  • Volatility: Medium to High
  • 243 ways to win
  • $250,000 max win
  • Special Features: Cow Feature; Buy Pass; Red mystery envelope

Carnival Cow Coin Combo offers the highly unique COW FEATURE, which triggers during the blue or green element features. To start, gold coins are scattered across the reels, each with a value between $0.40 and $100 based on bet size, plus some may be the mini or minor jackpot. The coins stay in place as the rest of the symbols spin, and if a green coin appears, all the gold coin values are awarded to the player. Not only that, but the Free Spins reset, the green coin becomes another gold coin, and you go again. And, potentially, again and again.

No other Coin Combo slot game offers the COW FEATURE, making the Carnival Cow slot the only way you can unlock this extremely profitable option. Just imagine winning the Mini and Minor jackpot, plus a bunch of other payouts, all at once. While it’s not likely, it’s far from impossible.
