777 Rainbow Respins RTP and Volatility


The slot features high volatility and 94.20% RTP.

The game has 94.20% RTP by default which is below the industry average. As for volatility, it's high which means that you will have to work hard to create a prize combination of premium symbols or activate a bonus feature. The advantage of this volatility is that you can get really big payouts!


777 Rainbow Respins

The design of this game is very simple and a little banal. The music is recognizably Irish, but pretty hard. Animated detail is almost non-existent, except for a constantly bobbing leprechaun that gets bigger when the 3 layers of his hat spin to give you a multiplier if you're lucky.

Let's take a look at the paytable! Lucky 7, rainbow, lyre, and double BAR are premium symbols while 4 suits of playing cards, star, month, horseshoe, and star have lower values. The Pot of Gold is the Bonus Scatter symbol and the 2x and 5x are the special Wild Multiplier symbols.

Bonus Rounds & Free Spins


Wild Multipliers

This is where you can benefit from Multiplier Wilds, and Wilds substitute for all regular symbols to help you create winning combos. The multiplier value is 2x in the base game and 5x Multiplier Wild symbols can land in the Bonus Round.

Other multiplier slots that we recommend:

Respin Insanity

Respin Insanity will be activated when you create a winning combination. This feature creates the so-called "Respin Zone". The Leprechaun Hat can spin to add 2x multipliers to the re-spin area, and this can happen 1 time per re-spin. Only the respin area will re-spin, and when you land identical symbols outside of the respin area, they will be added to the respin area and award 1 more respin. This bonus feature continues until you stop doing it.

Bonus Round

The bonus round will be activated when you land 3 Scatter symbols anywhere on the playing field. This feature will give you 4 free spins. Winning spins trigger the Respin Insanity feature just like in the base game, but now the Leprechaun can trigger 2x or 5x Wild Multipliers. All Wild Multipliers are frozen during this feature. This feature unfortunately cannot be re-run.

777 Rainbow Respins Demo Play

The provider has created a Demo mode for this slot machine, which allows you to spin its reels making bets with "fun" coins, not real money. This mode is easily accessible to every player and you don't even need to create a casino account to use it. Play for free for as long as you want! If you have used all the provided amount of "fun" coins, just reload the page with the slot machine and continue to test the game for free.

Max Win


Win up to 6,601x the bet.

The maximum that you can win in this slot machine is 6,601x the bet. This is not a good max win potential for a high volatility game but the top tier full-screen symbol only pays 31.75x so you definitely need the Wild Multipliers to make things better. Luckily they can increase up to 5x during the Bonus Round and become sticky.

Overall Rating


This slot machine offers unconvincing visuals, and the Leprechaun to the left of the playing field is more annoying than charming, at least in our humble opinion. Respin Insanity can indeed sometimes bring massive prizes, but the game suffers from ridiculously low symbol values. The full-screen top premium symbol only pays 31.75x so you definitely need Wild Multipliers to start winning big. We really like that they can go up to 5x in the Bonus Round and get sticky, but overall this slot is an uninteresting experience that feels half-baked from the get-go.

Winning:: 2
Multiplier: x12
A strange combination of classic theme, increased boards and exciting feautes.
The game is mostly about wild multipliers and respin feature, with the latter being basically unlimited. Of course, it’s unlimited only on paper, as even getting a series of 3 respins is not that easy.
Anyway, the game is a big fun. And can be about big wins. Just have some patience, as it’s often needed with high-volatile slots. Bonus hunt can be as long as 200+ spins. So be ready for hanging out. Neven

Winning:: €13
Multiplier: x65
High rainbow reels give you a feeling of sweet expectation. Actually the feeling was right. Wild multipliers land almost every second spin and help to achieve x10 payouts on a regular basis. Also there is a respin feature which works only in the part where the winning combination was. They said in the bonus round you have a chance to trigger up to x5 multiplier, but mine was the same x2 I had in base game. Nifty slot, you may give it a chance:)
