12 Coins Slot Game Overview

The 12 Coins slot game has a space-like blue background, and uses gold as its secondary colour. The betting panel looks unique and wider than what you may expect to see. You can also usually choose between low, standard, and high volatilities. Accompanying the gameplay is a fun soundtrack that may have you tapping your feet as you spin. 

The game is played on a 4×3 grid. However, each position on the grid acts as an individual reel, so there are 12 reels in total. 

Stakes range from a minimum bet of £0.10 up to a maximum of £10 per spin online at King Casino.

Symbols that may appear in 12 Coins include treasure chests, mystery icons, cash infinity icons and jackpot icons. There are no regular symbols, wilds, or scatters in the game. 

You can play the 12 Coins slot here at King Casino, the best online casino in the UK!

Hold the Jackpot Feature

To activate this bonus, you must land 4 bonus icons of any type across the centre row. If this happens, you will be awarded 3 respins. Any new bonus symbol that lands can reset the number of respins back to 3. If all the reels are filled with bonus symbols, or you run out of respins, the bonus game ends. 

During this bonus, you may land cash symbols that can win you 1x up to 5x your stake. You may also land mini, minor, or major jackpot symbols. You can potentially land more than one jackpot symbol during this bonus feature. The mini pays 10x, the minor 20x, and the major 50x. 

You may also land some more special symbols which can trigger extra features, as explained below: 

  • Cash Infinity: The cash infinity icons appear in the main game and can stay sticky on the reels until they’re transferred to the Hold the Jackpot bonus. During the Hold the Jackpot bonus, they are held in position while the others spin. These cash infinity icons can come with random payouts, ranging from 5x up to 10x your stake. 
  • Collector Symbol: During the Hold the Jackpot bonus, a collector symbol may appear and accumulate values from any cash symbols and cash infinity icons. After collecting the values, it multiplies them by a random value ranging from 1x up to 20x. 
  • Mystery Symbol: If the mystery symbol lands, it can change into any other symbol bar the cash infinity. You may also land jackpot mystery symbols which may transform into any of the mini, minor, or major jackpot icons.

Grand Jackpot

After the Hold the Jackpot bonus game ends, any wins are calculated unless the grand jackpot is won. To win the grand prize, you must land 12 bonus icons. If this happens, you can win the grand jackpot worth up to 750x your wager!

Return To Player

Return to Player (RTP): 96.13%

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.
