Action Boost 3 Lucky Rainbows Online Slot Review

The Action Boost 3 Lucky Rainbows slot is an Irish-themed game filled with classic emblems of the Emerald Isle. Pints of beer, lucky clover, and magical top hats appear over 5 reels, 4 rows of symbols, and 20 paylines. 

Pots of gold can trigger Rainbow Spins that lead to the special Action Boost features. These can play out on expanded reels with nudging wilds, symbol upgrades, multipliers, bonus credits, and jackpots of up to 5,000x. 

It’s a desktop and mobile compatible slot from Games Global in partnership with SpinPlay Games. There’s a high volatility here, matched with average returns of 96.27% and a guarantee of fair play at our recommended Slot Sites online.

How to Play the Action Boost 3 Lucky Rainbows Slot

The forest glade setting, traditional Irish symbols, and magical rainbow to one side will appeal to anyone who likes the hugely popular Celtic style. Harps, fiddles, and pointy green shoes are other items left on the reels by the lucky leprechaun. Green, red and purple rainbow strips run down the left of the reels, ready to unlock extra features.

You can pick from a bet range of 0.20 to 40.00 per spin at the best Betting Sites, which is 0.01 to 2.00 on each of the 20 paylines that run from the left. The ‘+’ above the main spin button takes you to autoplay and turbo modes, although due to local laws UK players can’t access these.

Tap the 3 small lines below this, followed by the ‘I’ tab to open a paytable, where you can review the extra features such as jackpots, and see a breakdown of symbol values. The hat is the most valuable and if you match this on 3, 4, or all 5 reels across a payline from the left you win 1x, 2x, and 10x your stake respectively. It’s also the Action Boost 3 Lucky Rainbows slot wild symbol with the power to substitute for others to complete extra wins and it appears stacked on reels to make this task easier. 

Jackpots and Other Action Boost 3 Lucky Rainbows Slot Features

Pots of gold on any reel trigger the Rainbow Spin feature. The green, red, and purple rainbow to the side will spin and colourful coins landing here will determine what bonus feature you get as they collect in matching pots above. 

Green Coin Action Boost – 5 free spins played on a 5x6 symbol grid with 40 paylines. All wild symbols nudge to fill reels, and any gold coins award credit prizes or another Rainbow Spin. The Rainbow Spin can also award an instant prize, or upgrade symbols to the valuable clover for the rest of the feature.

Red Coin Action Boost – 10 free spins where any gold coins award a Rainbow Spin or Shamrock bonus. Collect 3 green shamrocks to win the Mini jackpot of 10x the stake, and 4 blue shamrocks for the Minor jackpot of 50x. Collect 5 purple shamrocks for the 500x Major jackpot, and 6 red shamrocks for the Mega prize which pays 5,000x. 

Purple Coin Action Boost – 5 free spins where gold coins award 1 -2 extra free spins, a credit prize, or Rainbow Spin. Random 2x, 3x, or 5x multipliers apply to wins in this feature, and Rainbow Spins award further free games, or bonus prizes.

Multiple Coin Action Boost – If multiple pots fill you get the corresponding features at once. Depending on which pots trigger their features you get free spins, multipliers, shamrock collections, and 40 paylines at once.

Our Action Boost 3 Lucky Rainbows Slot Rating

There’s no actual leprechaun here, which we think is a missed opportunity, but it’s just a minor point that doesn’t take away from the bright graphics and rewarding gameplay. Everything centres around filling pots on Rainbow Spins, and once filled, the real action begins as free spins, jackpots, and more are all up for grabs. Fill 2 or even all 3 pots and you can claim big wins on every free spin.
