How to Play Double King Spins Online Slots

  1. Set your total bet amount. Before appearing in front of the kingdom, you will need to set your total bet. This is calculated by multiplying your chosen bet-per-line by the number of active win lines, which in Double King Spins are locked to 20. You can adjust you bet-per-line value between 1p and £10, by using the ‘+’ and ‘-’ buttons found in the ‘Bet’ menu in the left corner of your screen. If you decide to bet 20p per line, your total bet would be 0.20 x 20, making your total bet £4 per spin.
  2. Check the paytable. To learn more about the crowning combinations in this online slots realm, visit the paytable, located in the menu at the top-left corner of your screen.
  3. Spin the reels! Once you’re ready to begin your royal adventure, simply press the ‘Spin’ button to begin.

Reel Wins

On these regal reels any wins that you spin in are a multiplier of your bet-per-line. The value of your prize will be determined by the type of symbol you spin in and how many there are on a win line. In this kingdom you will need at least 3 matching symbols to spin in for a win to be granted. To find out more about each symbol and their multiplier rewards head to the paytable.

Just like the act of being knighted, all win lines will pay from left to right. You can only win once on each induvial line, but in this king-sized kingdom wins across multiple lines will be added together to form one total win! Any wins that you spin in are highlighted on screen and automatically added to your in-game credit, so that you never miss a moment in this super slots game.

King Spins

Now it’s time to introduce this online slots game’s crowning glory, the King Spins symbol. In this monarchy you could have the chance to double your win, with our Double King Spins feature. This symbol is no joke-r and you could soon find yourself with a king-sized win if it lands on your reels.

Spinning in a winning combination of King Spin symbols will automatically open this royal feature. A wheel spinner will appear at the bottom of your reels, with a 50/50 chance of landing on a x1 or x2 multiplier.

There’s no way you can lose with these King Spins, as landing on a x1 will grab you your original win. Landing on a x2 is where the crown jewels reel-y lie, as not only will you double your King symbol win, but this multiplier will also be applied to any other winnings from that spin!

Wild Symbol

There’s something pretty special about this online slots kingdom, and as you take to the regal reels you could soon find out why. The Wild symbol has the ability to substitute for almost every other symbol in the kingdom, even the King Spins symbol, to try and secure you some crown jewels!

For example, you’d have just missed out a royal win if you find to 2 A symbols on a win line. However your fortune could be about to change if you find a Wild symbol next to them, your loss will transform into a win worth 3 A symbols – isn’t that Ace!

Although this symbol has friends in high places, it can’t take the place of Free Spins symbols or knight you with the progressive Mega Jackpot. To take home that treasure chest, you will need to spin in all 5 Jackpot symbols on a win line. Spinning in a combination of Wild and Jackpot symbols could still bag you a king sized win.

Free Spins

You’ll feel like reel royalty if you spin in 3, 4 or 5 Free Spins symbols anywhere on your screen, as you’ll be awarded 5, 7 or 9 free spins, respectively.

These spins are locked to the value of your last paid for spin, but don’t worry you won’t be charged from your in-game credit – they’re a gift from the monarchy in this online slots game.

Not only do you have free opportunities to win, but the chances of the King Spins symbol appearing on your reels increases – so you could soon be doubling those free spin wins! Once you’ve taken all your free spins you’ll head back to the main reels, with any winnings being added to your on-screen credit automatically.

Progressive Mega Jackpot

The occurrence of 5 (five) “JACKPOT” Jackpot symbols on an active win line awards the progressive Mega Jackpot. The progressive Mega Jackpot is available on any bet, with 0.025% of the bet being added to the progressive pots.  Half of the value gets added to the current jackpot, and half to a reserve pot ready for the next winner.

When the Jackpot is won, it is reset and begins to rise again. Simultaneous wins can occur. If a player wins the progressive Mega Jackpot then a notification would occur BEFORE any other player was awarded the Jackpot. Any players in a game that contributes to that same Mega Jackpot will receive the on-screen notification of a reset the next time they press the spin button if it is within 10 minutes of the jackpot being won. Players will not be charged for the spin generating this notification.

The Mega Jackpot guaranteed starting value is £100,000, with even higher starting prizes possible with a built up reserve pot. The Mega Jackpot promotional pot system is available over any stake on any participating game plugged into the Mega Jackpot promotional pot.

In the event of a communication error after a progressive win result has been determined and before it has been displayed on screen, the win amount will automatically be transferred to the player’s account. While the game is live, the Jackpots cannot be terminated.

Promotional Terms and Conditions

Section 6: Valid Stakes, Bets or Wagers

You may stake up to the amount of the balance available in your Account. We do not offer Accounts with a credit facility.

Winnings which are generated from promotional free spins will go into your Bonus Credit Account.

When a bet or stake is placed and confirmed, the corresponding amount is deducted from your Account balance.

Game specific rules will be made available to you when you start playing a game. These rules can be located on the Website and within each game. These are referred to as the Rules of the Games. It is your responsibility to read and understand these game specific rules before you start playing.

It is your responsibility to check that the bet instructions you have submitted are correct before committing to play.

Winnings from deposits will go into your Cashable Credit Account.

All bonuses (including winnings from promotional free spins) will be credited to your Bonus Credit account and are subject to the Bonus Credit Wagering Requirement. Winnings from Bonus Credit will also be credited to your Bonus Credit account.

Once your Bonus Credit Wagering Requirement Balance is £0, any remaining Bonus Credit will automatically be transferred as winnings to your Cashable Credit account.

If your Bonus Credit Account Balance is £0, you should contact us to remove any remaining wagering requirements from your account. You can contact our Customer Support Team on 01384 885046.

In the event that you withdraw Cashable Credit before you have met your Bonus Credit Wagering Requirement (i.e. before your Bonus Credit Wagering Requirement Balance is £0) your Bonus Credit and Bonus Credit Wagering Requirement will be reduced by the same percentage that you have withdrawn from your Cashable Credit. By way of example only: you have made a first deposit of £10, credited to your Cashable Credit account, and received a first deposit match bonus of £10, credited to your Bonus Credit account; your Bonus Credit Wagering Requirement Balance is £400 (i.e. 40 x bonus of £10); you play through your £10 deposit once on a slots game and win £50. Your Bonus Credit Wagering Requirement Balance is unchanged (as you have not yet staked any Bonus Credit); you are free to withdraw the £50 winnings, stored in your Cashable Credit account, but you choose to only withdraw £25 (i.e. 50%); as your Bonus Credit Wagering Requirement Balance is not yet £0, you will forfeit 50% of your Bonus Credit (reducing it to £5) and your Bonus Credit Wagering Requirement Balance will be reduced by 50% (reducing it to £200).

If bonus abuse is discovered we may at our discretion remove rewards as outlined in section 7b.

In the event that you stake both Cashable Credit and Bonus Credit, any winnings will be applied proportionately to your Cashable Credit and Bonus Credit accounts and your Bonus Credit Wagering Requirement Balance will be reduced only by the amount of Bonus Credit used. By way of example only: you have deposited £5, credited to your Cashable Credit account, and have received a first deposit match bonus of £5, credited to your Bonus Credit Account; your Bonus Wagering Requirement is £200 (i.e. 40 x bonus of £5); you elect to stake £10 on a slots game; as you do not have enough Cashable Credit to cover your stake, the remaining £5 (50%) will be deducted from your Bonus Credit and your Bonus Credit Wagering Requirement Balance will be reduced by £5 to £195; you win £50; £25 of your winnings (i.e. 50%) will be credited to your Cashable Credit account; and £25.00 of your winnings (i.e. 50%) will be credited to your Bonus Credit account.

When betting on our betting and gaming products, the percentage of your stake that will contribute to the Bonus Credit Wagering Requirement is as follows:

Betting and Gaming Product %
Slots 100
Bingo 100
Roulette 10
Blackjack 10

When playing with Bonus Credit winnings from Casino games, the wagering contribution taken from the remaining bonus wagering will be the contribution % of the Casino game that the winnings came from, regardless of which game in being played. For example, if you win £10 on Roulette, then play with that £10 in a Slots game, the wagering contribution for the slots play will be 10% (the Casino game Wagering Contribution).

Stakes from your Account will be made in this order:

  1. free spins (if any);
  2. any amounts in your Cashable Credit Account which comprise of winnings from bonus credit;
  3. any amounts in your Cashable Credit Account which comprise of winnings from deposits;
  4. any deposited amounts in your Cashable Credit Account; and
  5. any bonus amounts in your Bonus Credit Account.

By placing a real money bet, you warrant that you are legally able to do so within your jurisdiction and that you accept that we are unable to provide any warranties as to the legality or otherwise of your participation in real money play. It is your responsibility to determine if remote gambling is legal in your jurisdiction.

In the event of a disconnection from the service whilst you are using our betting and gaming products, you are advised to log back in as quickly as possible. If you experience disconnection difficulties on a regular basis, please consult your service provider as to what measures can be initiated to help reduce this risk. We shall not be responsible for any damages, liabilities or losses suffered as result of the disconnection of Players during play.
