Last Updated on February 22, 2026 by author

The world of online slots is constantly evolving, with developers racing to trademark the next big mechanic that keeps players glued to the screen. Enter SpinPlay Games (under the Games Global umbrella) and their electrifying “Action Boost” engine. While players often search for “Action Boost Fortune,” they are most likely hunting for the flagship fortune-themed title that put this mechanic on the map: Action Boost 3 Lucky Rainbows.

This review dives deep into the “Action Boost” phenomenon, focusing on the game that defines the “Fortune” experience—where pots of gold, shimmering coins, and triple-tiered bonus rounds collide to create a wealth-building adventure.

Unlock the Pots of Gold & Mega Wins

If you are chasing the thrill of wealth, luck, and dynamic gameplay, the Action Boost series by SpinPlay Games is likely on your radar. Often referred to by players simply as “Action Boost Fortune” due to its heavy emphasis on gold coins, jackpots, and lucky charms, the standout title in this category is Action Boost 3 Lucky Rainbows.

This slot isn’t just another Irish-themed game; it’s a masterclass in the “collection pot” mechanic, offering three distinct bonus rounds that can trigger individually or—if Lady Luck smiles—simultaneously for massive payout potential.

Game Overview

At its core, the Action Boost engine is about collecting coloured coins to fill meters (or pots) that trigger specific enhanced features. In the “Fortune” context (Action Boost 3 Lucky Rainbows), the game is set against a vibrant, magical forest backdrop filled with leprechaun lore, four-leaf clovers, and overflowing pots of gold.

Quick Stats Table

The “Action Boost” Mechanic Explained

What makes this game unique? It’s the Action Boost itself. Unlike traditional slots where you wait for 3 scatters to land on a single spin, this game uses a Coin Collection System.

Above the reels sit three massive Pots of Gold:

• Green Pot (Reel Expansion)
• Red Pot (Jackpot)
• Purple Pot (Multipliers)

Whenever a coin of a specific colour lands on the reels, it flies into its corresponding pot. This does two things:

1. Wild Transformation: The coin leaves a Wild symbol behind (or collects to the pot), helping base game wins.
2. Trigger Chance: Every single coin offers a chance to trigger the Action Boost Free Spins associated with that colour.

Pro Tip: The pots growing in size is purely visual (a “perceived accumulation” mechanic). The chance to trigger is random on every coin land, meaning you could trigger a bonus on your very first spin or your fiftieth.

The 3 Bonus Features: A Trinity of Luck

The magic of “Action Boost Fortune” lies in its three unique Free Spin modes. You can trigger one at a time, or if you land multiple coloured coins on the triggering spin, you can activate a Combo Bonus combining their features.

The Green Coin Action Boost (Expanding Reels)

When the Green Pot activates, the game transforms.

• Reel Expansion: The grid grows from 5×4 to 5×6.
• Payline Boost: Paylines double from 20 to 40.
• Nudging Wilds: Any reel containing a Wild symbol will nudge to become a Wild Reel (fully stacked wild), guaranteeing massive coverage.
• Spin Count: 5 Free Spins.

Why players love it: This mode is the volatility driver for line hits. The stacked wilds on a taller grid create the most frequent “big win” screens outside of jackpots.

The Red Coin Action Boost (Jackpot Fortune)

Triggered by the Red Pot, this is where the “Fortune” element truly shines.

• Jackpot Collection: Gold coins landing during these spins can reveal a jewel associated with one of four jackpots.
• The Prizes:
  • Mini: 10x Stake
  • Minor: 50x Stake
  • Major: 500x Stake
  • Mega: 5,000x Stake
• Spin Count: 10 Free Spins.

Why players love it: It offers the highest single-payout potential. Collecting enough jewels to hit the Mega Jackpot is the ultimate goal of the game.

The Purple Coin Action Boost (Multipliers)

The Purple Pot adds a layer of unpredictability to your wins.

• Random Multipliers: On every spin, a random multiplier of 2x, 3x, or 5x is applied to the win.
• Extra Spins: Gold coins can award +1 or +2 extra Free Spins.
• Cash Credits: Gold coins can also award instant cash prizes.
• Spin Count: 5 Free Spins.

Why players love it: Even small line hits can become significant wins when a 5x multiplier is applied unexpectedly.

The Ultimate “Action Boost”: The Combo Trigger

The holy grail of this slot is triggering all three pots simultaneously. If you achieve this, you play 10 Free Spins on an expanded 40-line grid, with Nudging Wilds, random Multipliers (up to 5x), and the chance to win the Jackpots. This is where the game’s math model really flexes its muscles.

Visuals, Audio, and Theme

SpinPlay Games has nailed the aesthetic of a premium “Vegas-style” video slot.

• Graphics: The symbols are crisp and high-definition. The gold coins sparkle with a satisfying animation as they fly into the pots. The transition from base game to bonus is seamless, with the rainbows arching over the reels to signal big potential.
• Soundtrack: A lively, upbeat Irish jig plays during the base game, increasing in tempo and intensity during the Action Boost features. The sound of coins hitting the pot is distinct and dopamine-inducing.

It’s worth noting that while the “Irish Luck” theme is overused in the industry, the Action Boost execution makes it feel modern and less “cartoonish” than older rivals like Rainbow Riches.

RTP and Volatility: What to Expect

The “Action Boost Fortune” experience is a classic High Volatility ride.

• The Grind: You may experience long periods of dead spins or small “top-up” wins in the base game. The game relies heavily on the bonus rounds to deliver returns.
• The RTP: The default RTP is 96.27%, which is above the industry average of 96%. However, be cautious: some casinos may run lower versions (around 94% or 92%). Always check the “Help” file before playing.
• Max Win: The cap is 5,000x your bet. While not as high as some “extreme” slots (which go up to 50,000x), the 5,000x is more achievable and usually tied to the Mega Jackpot.

Pros and Cons

Every fortune has its price. Here is an honest look at the highs and lows of the game.

Pros

• Engaging Collection Mechanic: Seeing the pots fill up keeps the base game exciting.
• Triple Bonus Potential: The ability to combine bonus features (e.g., Multipliers + Expanding Reels) creates explosive gameplay.
• High Hit Frequency: At nearly 29%, you get frequent small wins that help sustain your balance.
• Mobile Optimized: SpinPlay designs for mobile-first, so it plays perfectly in portrait mode on smartphones.

Cons

• Misleading Pots: New players often think “full” pots must trigger a bonus soon. This is the Gambler’s Fallacy; the trigger is random, and full pots are just visual flair.
• Low Base Game Pays: Without the Action Boost features, the base game line wins are relatively weak.
• Generic Theme: If you hate leprechauns and rainbows, the theme offers nothing new.

Comparison: How it Stacks Up

Is Action Boost 3 Lucky Rainbows the best “Fortune” slot out there?

Final Verdict

The “Action Boost Fortune” experience (via Action Boost 3 Lucky Rainbows) is a stellar example of modern slot design. It takes the popular “pot collection” trope and enhances it with the Action Boost modifier, ensuring that the bonus rounds feel distinct and rewarding.

While the base game can feel like a waiting room for the main event, the adrenaline rush of triggering a Red + Green + Purple Combo Bonus is unmatched. If you enjoy high-volatility slots where the features can stack on top of each other for chaotic wins, this game is a pot of gold worth chasing.

Score: 8.5/10
