Elegant affair with the 15 Coins slot

This slot is virtually the same as its predecessor, 12 Coins, but the action this time plays out over five reels rather than the original four.

The design is stylish and elegant with lots of reds and golds, which are considered lucky in East Asian cultures.

How to play 15 Coins

This is a very similar slot to the 12 Coins game. If you have never played that one before, here is what you need to know:

  1. Click one of the three chance level options or use the green button to turn this feature off.
  2. The volatility level is shown with a chilli meter; the more chillis that are lit up, the higher the variance.
  3. The plus and minus coin stack buttons allow you to set your bet. Never bet more than you can reasonably afford to lose and make use of safety features such as timeouts and self-exclusions if you need them.
  4. The three-bar menu opens the main settings options.
  5. There are no standard winning symbols in this slot; the winning symbols are all bonus icons.

The full title of this game is 15 Coins Hold the Jackpot Cash Infinity, giving a nod to the extras you might uncover if you decide to give this slot a try. Let’s have a look at the 15 Coins bonus features and see whether they might offer something for you:

Bonus symbols

Land five of any kind of bonus icon on the central horizontal row of the grid to launch the Hold the Jackpot bonus game.

Cash Infinity

Cash Infinity icons can appear randomly during the base game. These are sticky symbols that stay on the grid until the jackpot bonus round ends.

These symbols offer win multiplier prizes of 5x to 10x your bet. It is also worth noting that landing a Cash Infinity icon on the middle row means you will have a greater chance of triggering the Hold the Jackpot bonus.

Hold the Jackpot

As indicated already in this 15 Coins slot review, this is the major feature of the slot. It is played on the whole grid and all the bonus icons will stay locked in place.

You start with respins, which reset each time another bonus icon lands. The game continues until you run out of respins or bonus symbols take up every position on the grid.

Special symbols

During the feature, cash symbols can reward you will win multiplier values from 1x to 5x your bet. There are also mini, minor and major jackpot symbols that can appear and earn you one or more of the jackpot prizes.

The jackpot wins are based on a win multiplier applied to your bet. These are:

  • Major = 50x your bet
  • Minor = 20x your bet
  • Mini = 10x your bet

Collector symbols

These can land and accumulate Cash Infinity and cash symbols. They also add a random multiplier of between 1x and 20x.

Mystery symbols

These can transform themselves into other bonus icons, apart from the Cash Infinity symbols. There are jackpot mystery icons that can become one of the three jackpot symbols.

These mystery symbols and the jackpot mystery symbols open up to reveal your fate at the end of the bonus game.

Grand jackpot

This is worth 1,000x your bet and offers the biggest total win in the game. You can unlock this payout potential by filling every position on the grid with a bonus symbol.
