777 Rainbow Respins Slot (Microgaming)

777 Rainbow Respins Slot (Microgaming)Slot machines featuring lucky-themed graphics are popular, and the leprechaun and his pot of gold appear to be one of the most popular choices for developers.

777 Rainbow Respins is another of those games, and although the concept isn't particularly original, the features on the reels are quite different. Not only does the game offer a unique game area compared to what other competitors are offering, but there are also some intriguing areas to explore.

This is what I experienced while playing 777 Rainbow Respins for real money:

Game Set-Up

777 Rainbow Respins comes with a 4x7 reel design, with up to 127 active lines. As usual with Microgaming/ Crazy Tooth Studio slots, this one also comes loaded with great features that include a Respin Insanity mechanic, 2x or 5x multipliers, and free spins.

Betting and Prizes

Real money wagers here start from a low of $0.20 to a high of $40 per spin. A top jackpot of about 6,500x the stake is what you can expect from 777 Rainbow Respins.

Such a high payout often points to high volatility and this is the case with this slot. However, I'm happy that the developer has also considered a fair RTP of  96.10%. Bear in mind that Microgaming has allowed online casinos to offer lower RTP values, so be sure to confirm with your casino.

777 Rainbow Respins Slot Features

One of the features that got my eye is the Respin Insanity. It’s an interesting feature that requires triggering some winning spins.

Once you form a winning combo the respins will follow, and with them, you get an opportunity to trigger additional prizes. The respins will happen for the area that’s formed (often between the winning icons and all others from the same type).  

Also, the area may expand via the symbols that land inside it, but this is only possible if they match some of the ones shown outside.

You will see the leprechaun is sitting close to the reels, and he will bring you some multipliers (2xs). These come in the form of four-leaf clovers which serve as wild symbols.

Lastly, we have a Pot of Gold which acts as the scatter/bonus symbol. This is the feature that I used to trigger 4 free spins, and with just 3 of them, the free spins will be right in your hands.

Theme & Design

The background isn’t all that interesting and the only thing there is a common casino-style wallpaper. However, on the sides are a leprechaun and a rainbow.

The symbols present are mostly Irish-related, but the developer has thrown in a few classics. These symbols are the Pot of Gold scatter, Four-leaf clover multiplier, Sevens, Moon, Rainbows, Harps, Bar Logos, Star, Horseshoe, and the low-pay card suit icons.


With its decent potential, a fair RTP, and some unique mechanics, I found 777 Rainbow Respins to be a very good title from Microgaming.
