Getting Started with Rainbow Slots

Want to see if you can river-dance your way to a big online casino win? Then put your best foot forward and give Rainbow Slots a try! Simply tap the ‘Bet/Lines’ button to begin, and use the ‘+’ and ‘-’ buttons to adjust your bet amount and the number of win lines you’re playing with. You can take a spin in this forest for as little as 2p a line, with the maximum bet-per-line set at £20. Depending on how many lines you’ve selected to play, your total bet shown at the top of the ‘Bet/Lines’ menu will adjust.

Your total bet amount is calculated by multiplying the number of win lines by the value of your bet-per-line. For example: a 10p bet across all 9 win lines would see you spend 90p a spin, while betting £1 across 5 win lines would cost £5.

To start spinning, simply close the menu using the downward arrow, and tap the spin button!

How to Play Rainbow Slots

If the total bet amount is looking grand, and you’ve settled on the number of win lines you want to play on, tap the spin button to start the reels.

On Rainbow Slots, the win lines pay left to right on these crackin’ reels. There are plenty of colourful combinations of symbols at play in Rainbow Slots, with some paying out with 2+ symbols on a win line, while others will pay with 3 or more.

The sun will shine on any wins on an active win line, before they’re added to your credit automatically.

Reel Wins

Will your spin give you a rockin’ prize? All wins are awarded as a multiplier of your original bet-per-line, with each winning combination being worth a different multiplier prize. You can view the full paytable and winning combinations you’ll need via the menu in the top left corner.

Wins across multiple win lines are added together to form a total win, with only the highest win across a single line counting towards your total. The total is then added to your credit automatically.

Wild Symbols

You could find yourself with some serious Leprechaun loot if you see one of our Wild symbols on an active win line! That’s because they substitute for all symbols – except for the mini-game and Free Spin symbols – giving you a win!

For example, if you lined up two K symbols and a Wild, the Wild would serve as a K giving you a total win worth three Ks! Don’t have a paddy, but the progressive Jackpot cannot be won with a Wild on your winning line – though you’d still get a crackin’ win!

Lucky Lapper Mini-Game

If you fancy Dublin’ your money, there’s Celtic cash a’plenty up for grabs in the Rainbow Slots mini-game, Lucky Lapper. Enter the mini-game with two or more Leprechaun symbols in a row on an active win line – the more mini-game symbols you have, the bigger the prizes up for grabs.

In Lucky Lapper, you need to guide Dr Slot’s lucky Leprechaun around a board filled with mega multipliers – and of course, the odd trap. Press the spin button to roll the dice, and move that number of spaces around the Lapper.

Land on a square with silver or gold coins to win that multiplier amount, or land on the mystery shamrock symbol to walk away with a HUGE hidden bonus. You can keep moving around the Lapper collecting prizes until you land on a dangerous Venus fly trap!

These traps will gobble you up and send you back to the main reels. Don’t worry though; you’ll keep any prizes you’ve accumulated up to this point.

Gamble Feature

If you’re feeling bold, Rainbow Slots has a grand Gamble Feature that could see you double, triple or multiply your wins by even more! Use the ‘Gamble’ button below the reels to set your Gamble feature preferences. However, you’re unable to gamble wins above £200.

If you decide to turn it on and you spin a win, you’ll enter a clearing where you’ll find a selection of tree stumps. Select the multiplier you want to play for, but bear in mind that the higher it is, the harder it will be to win! When you’ve made your choice, press the spin button. If the arrow lands on the multiplier, you’ll win it! If you land on a losing segment, you’ll lose your original win and return to the reels with nothing.

Right up until you hit the spin button, you can still change your mind and keep your initial win – just press ‘Collect’.

Free Spins

Keep an eye out for the Free Spin symbols across your reels! 3, 4, or 5 of these Free Spin symbols will give you 5, 7 and 9 free spins respectively, as long as they’re on an active win line. Any free spins you bag will be locked to the value of your last paid-for spin.

Progressive Jackpot

The occurrence of 5 (five) “JACKPOT” Jackpot symbols filling a win line on every reel 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 £150,000, 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.
