How 777 Rainbow Respins™ Compares to Other Slot Games

This setup gives the slot a total of 127 active paylines, which can grant a win. Since symbols tend to appear stacked, there is also the unique possibility for players to land a major win for a single symbol covering the entire grid.

777 Rainbow Respins™ Symbols and Payouts

Like many other slots, 777 Rainbow Respins™ also features low-value symbols as well as high-paying icons. Winnings are awarded when the same symbol lands on an active payline three or four times. While the slot consists only of four reels and there is no payout for five-of-a-kind, there is a special combination of symbols that may bring players a rather high win. If a symbol covers the entire gameboard, players will enjoy significantly higher returns.

In addition to the regular symbols, 777 Rainbow Respins™ features several special icons that can unlock the bonus functions of the slot and increase one’s profit. The slot features two types of multiplier Wilds and a Scatter, which can trigger the Free Spins feature of 777 Rainbow Respins™. That way, lucky players can boost their profit with a single spin on the slot.

Bonus Features Overview

While the base game offers players multiple ways to land a win, with 777 Rainbow Respins™ having 127 paylines, triggering the special features of the slot can open the door to even bigger wins. This CTS slot incorporates multiplier Wilds, Scatters, and various re-spin features in its gameplay. What is more, thanks to the bonus functions of 777 Rainbow Respins™, players might get a full gameboard covered by the same symbol and enjoy extra high payouts.

Wilds and Scatters

As soon as you give 777 Rainbow Respins™ a few spins, you will notice a few non-paying but special symbols appearing on the reels of the slot. The Wilds of this slot will actually have a double function since they will both substitute for regular paying symbols and will also carry either 2x or 5x multiplier value. Every time a Wild is part of a winning line, it will multiply the win by its respective value.

While the 2x Wild appears both in the base game and during special features, the 5x Wild may appear only during the 777 Rainbow Respins™ Bonus game. As for the Scatter Pot of Gold symbol, it will appear only on the first, second, and fourth reels. When it appears three times in the base game, the Scatter will trigger one of the special features of 777 Rainbow Respins™.

Free Spins

Every time you hit a win while playing 777 Rainbow Respins™, you will be rewarded with extra chances of landing even more wins. When players land a winning combination, it will unlock the Respin Insanity feature, with every symbol from the win being included in a respin area. All symbols, which have been highlighted in the special section, except for the 2x Wilds, will respin.

If the symbol within the entire respin area matches other positions outside the highlighted symbols, the respective sections will be added to the respin area and the feature will be retriggered. After every respin a 2x Wild may be awarded to the special area, with the whole gameboard being evaluated for extra wins. If symbols within the respin area do not match positions outside of that area, the Respin Insanity feature ends, and players return to the base game.

When you see three Scatters on the gaming screen, you will see the 777 Rainbow Respins™ Bonus game start, with the symbols that have triggered the feature being transformed into 2x or 5x locking Wilds. The bonus game awards four free spins, with wins during this feature triggering the Respin Insanity function. Unfortunately, as Scatters do not appear during free spins, the 777 Rainbow Respins™ Bonus game cannot be retriggered.
777 Rainbow Respins™ Free Spins


As already mentioned, 777 Rainbow Respins™ creators have decided to attach a 2x and 5x multiplier to the Wilds in the game, adding an extra boost to Wild wins. The 2x Wild can be seen in the base game, during Respin Insanity rounds, and during the free spins of the 777 Rainbow Respins™ Bonus game. To grant even bigger bonus rewards, the free spins may also feature the 5x Wild.

During the base game, the 2x Wild can substitute for regular paying symbols and help players complete lines. The multiplier is then added to Wild wins and will remain locked in its position when the Respin Insanity feature is played. You will notice that during the spins, the leprechaun will dance to Irish tunes, while his hat is spinning. If the hat happens to reveal a 2x multiplier, it will be added to the respin area during the Respin Insanity feature.

777 Rainbow Respins™ FAQs

  • What is the RTP of 777 Rainbow Respins™?
  • The official RTP that 777 Rainbow Respins™ was released with is 96.10%, which is a rather good rate, surpassing the market average of 96%. However, the software company offers alternative RTP versions of 777 Rainbow Respins™, which is why you may across a variant of the game offering a lower RTP.
  • What is the volatility of 777 Rainbow Respins™?
  • 777 Rainbow Respins™ is a video slot with high volatility, which may be appreciated by high-rollers. Playing with high volatility usually means that players might go through quite a few losing rounds until they hit a major payout. While this slot may offer very generous wins, recreational players must be careful as high volatility may exhaust their bankroll rather quickly.
  • How are wins evaluated during the Respin Insanity feature?
  • When winning combinations in the screen are added into a respin area, all positions within this area respin to reveal the same symbol on all positions. When these symbols match a symbol outside of the respin area, the feature is retriggered, adding the new matches to the respin area. That said, if Wilds land in the respin area, they may form winning lines with outside symbols even when they do not match positions within the respin area. In that case, all wins are evaluated, and the feature ends.
