15 Coins Slot Game Overview

The treasure-themed slot offers a Hold the Jackpot Bonus Game, and a maximum potential payout of up to 1,000x your stake.

15 Coins is available to play on all mobile devices, including smartphones.

How To Play 15 Coins

You’ll notice that the game controls appear at the bottom of the screen after the slot loads.

You can adjust your bet by choosing one of the coin values at the bottom, or you can use the + and – keys.

Click the red Spin arrow to start playing.

Unlike a lot of online slots, there are no regular base game symbols in 15 Coins. Instead, all 15 reel positions spin as individual reels, and if you land 5 bonus coin symbols across the middle row, it will activate the Hold the Jackpot Bonus Game!

Cash Infinity Symbol

The Cash Infinity symbol can potentially help trigger the bonus game if it lands on the middle row during the base game.

During the bonus round, Infinity symbols can award cash prizes ranging from 5x up to 10x your stake. Additionally, Infinity symbols can remain sticky until the end of the bonus game.

Hold the Jackpot Bonus Round

Triggering the Hold the Jackpot Bonus Game requires 5 bonus symbols to appear on the middle row alongside any sticky Cash Infinity symbols. The feature starts with 3 re-spins, and the tally resets if any new bonus symbol lands. Lastly, if any bonus symbols land, they turn sticky.

Cash Bonus symbols

If any cash bonus symbols land, they can have cash prizes ranging from 1x up to 5x your stake attached. Mini, Minor, and Major jackpot symbols could also land during the feature. Plus, the jackpot symbols come with possible prizes attached. For example, the Mini can win you 10x your stake, the Minor can pay 20x your stake, and the Major can award a 50x your stake jackpot!

You might also notice the Accumulator or Collect Symbol, which can collect prize values from any visible cash symbols and Cash Infinity symbols. Then, a random multiplier ranging from 1x to 20x can be applied to your total possible payout.

Alternatively, Mystery Symbols and Jackpot Mystery symbols can also appear during the bonus feature. The regular Mystery Symbol can transform into a random bonus symbol when the feature ends.

However, note that it cannot transform into the Cash Infinity symbol. On the other hand, the Jackpot Mystery symbol can turn into one of 3 jackpot symbols.

If matching symbols appear on all 15 positions on the grid, they trigger the Grand Jackpot worth up to 1,000x!

Return To Player

Return to Player (RTP): 96.07%

RTP is used to explain the potential money that an online slot or casino game can pay back to players. It appears as a percentage and is generally calculated from gameplay over a long duration of time.

For example, if a slot has a RTP of 97% this means that it could pay back £97 for every £100 wagered.

However, there is no guarantee that players will receive this amount, as slot payouts are entirely random.
