777 Rainbow Respins Game Overview

The 777 Rainbow Respins slot, developed by Crazy Tooth Studios and Microgaming, combines the classic slot machine theme with a touch of Irish magic. It is essentially a clone of the studio’s previous game, 777 Mega Deluxe, but with a whimsical Irish twist. 

The game’s visuals blend cheerful rural scenery with an indoor casino atmosphere, depending on the stage of the game. The leprechaun symbol standing on a rainbow to the left of the game board adds to the game’s charm and whimsy. 

777 Rainbow Respins slot is a high-volatility slot with a return to player percentage (RTP) of 96.10%. This online slot game is available to play on mobile, tablet, and desktop devices, and the bet size is between £0.20 and £20.

With 127 fixed paylines, you can form winning combinations if you land at least 3-of-a-kind symbols across a payline. The highest payouts are reached if you land a gameboard full of the same symbol. 

The game features a wide range of symbols, including clubs, diamonds, hearts, cubs, stars, moons, horseshoes, and suns as the low-paying symbols. The rainbows, harps, and bars symbols are worth slightly more, with the highest payout being up to 25.4x your stake for a gameboard full of rainbows (the most lucrative mid-level symbol). The 7s symbols are the most lucrative, with a payout of up to 31.75x your stake for a gameboard full of them. 

The game also features the gold pot scatters and 2x – 5x wild multiplier symbols. The 5x multiplier only appears in the bonus game.

You can play the 777 Rainbow Respins slot game here at King Casino, the best brand new casino in the UK.

Respin Insanity Feature

You can trigger the Respin Insanity feature with winning spins. Once this feature is triggered, the winning symbols form a respin area on the reels with all symbols in the area except multipliers respinning. 

Additional winning symbols can increase the size of the respin area and trigger more respins. A wild x2 multiplier symbol may be added to the respin area after each respin. The feature ends if there are no more symbol positions added to the respin area.

The bonus round is triggered by landing 3 gold pot scatter symbols, awarding 4 spins. The Respins Insanity feature remains active during winning spins and x5 wild multipliers are introduced. 

The triggering scatter symbols transform into either x2 or x5 symbols, and remain in place for the duration of the feature. All other wild multipliers that may land also become sticky during this round. 

Unfortunately, you can’t retrigger this bonus round.

Return To Player

Return to Player (RTP): 96.10%

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.
