Action Boost Gladiator Slot Review
Three pots of gold sit above the reels of Action Boost Gladiator, and they’re the whole game. The reels underneath pay the bills between collections, but everything that matters happens on the arena wall: which bag is filling, which colour you’re chasing, and which of three very different bonus rounds you’re about to walk into.
The argument here is that filling those pots matters more than anything the reels do alone. SpinPlay Games have made the colour chase the whole point of the base game, and the payoff is three bonus rounds that behave nothing like each other.
It runs on a 5×4 grid with 20 to 40 fixed paylines, at 96.27% RTP and high volatility, with stakes from 0.20 to 40.00 per spin and a hit rate of 33.68%. It joins Action Boost Tiki Treasures and Action Boost 3 Lucky Rainbows in the same series, and the pots have never stood in a livelier arena.
Base Game & Features
Wins need matching symbols on a connected payline, paid left to right across the five reels. Where several combinations land on one line, only the highest counts. It’s a familiar arrangement, and the fixed line count means there’s nothing to configure.
Each spin costs a total bet built from an initial bet multiplied by the cost of the paylines played, and line wins pay out against that initial bet. The total payout for a spin is the sum of every payline win on it.
The Coliseum symbol is Wild, substituting for everything except the Coin symbols, and it can form its own winning line. That exclusion matters more than it sounds, because the coins are what the game is actually about.
The Coin Collection
Four special symbols drive everything, and each behaves differently:
- Green, Red and Purple Coins collect into the bag of the same colour above the reels
- Trophy Coin collects to the trophy on the left-hand panel
- Gold Coin appears only inside the features, where it carries the prizes
- Coliseum Wild substitutes for everything except the coins
Every coloured coin that lands moves its pot closer to paying out, and the combination of colours collected when the feature fires determines which bonus round you get. The Trophy Coin is the separate route: each one carries a chance of triggering the Flag Spin feature, which sits between the base game and the bonuses like a gate.
Action Boost Gladiator Bonus Features & Free Spins
Flag Spin
When a Trophy Coin triggers the Flag Spin, every flag activates and one Flag Spin is awarded. Coins landing on flags fire the Action Boost Free Spins, with the colour combination of those coins deciding which boost applies. The Flag Spin can also drop one of the four jackpots on a single spin.
Green Coin Action Boost
Five free spins, played on 40 lines with all reels grown to six symbol positions. Every Gold Coin awards a bonus credit prize or a Flag Spin, and the Flag Spin either pays a credit prize or upgrades a symbol to Gladiator for the rest of the round, with upgrades applied before wins are paid.
The twist is the wild treatment: any reel showing a Wild gets nudged until every position on it is Wild, with wins paid after the nudge. Full wild reels on a grown grid is a serious swing.
Red Coin Action Boost
Ten free spins, and this is the jackpot round. Gold Coins award shields, credit prizes or Flag Spins, and Flag Spins can hand out more shields, a prize or a jackpot boost that raises the relevant jackpot value for the remainder of the round. The ladder to climb:
- 6 Red Shields wins the MEGA jackpot
- 5 Purple Shields wins the MAJOR
- 4 Blue Shields wins the MINOR
- 3 Green Shields wins the MINI
Complete a set and that jackpot is paid, and the collected shields for it reset rather than closing the round, so a good set of spins can climb the same ladder twice. The ladder’s proportions are fixed: MEGA pays 5,000x the bet, MAJOR 500x, MINOR 50x and MINI 10x, whatever the stake.
Purple Coin Action Boost
Five free spins with a random multiplier of 2, 3 or 5 on every spin, applied to all line wins and bonus credit prizes. It’s the round that keeps feeding itself, because the Gold Coins here can extend it as well as pay:
- Gold Coins award a credit prize, 1 or 2 extra free spins, or a Flag Spin
- Flag Spins pay a credit prize or add up to 3 more free spins
- The random multiplier applies to every line win and credit prize
A fresh multiplier is drawn on every one of those spins, so a 2x followed by a 5x is a normal sequence, and any line win landing on the 5x spin is the round’s biggest moment. The multiplier never touches jackpots, because there are none to touch in this round.
Multiple Coin Action Boost
Land more than one coin colour on a single base spin and the free spins run with every triggered boost at once. Ten spins if Red is among them, five otherwise. The Purple multiplier applies to line wins and credit prizes but never to jackpots.
That combination is the whole point of the collection system: green and red together put wild nudges and the shield ladder in the same round, while purple layered over either multiplies everything those rounds pay in credits. The bet multiplier stays the same as the game that triggered the feature.
The ceiling on all of it is the MEGA jackpot at 5,000x the bet, and that’s the number the whole build points towards.
Our Honest Verdict
Overall Rating: 7.7/10
A session here is mostly watching the arena wall: three pots filling coin by coin, each colour a different promise. That build is the one reason to choose it, because the Red pot’s shield ladder is a completely different game from the Green pot’s wild reels, and knowing which one you’re close to changes how every spin reads.
The strength is that the three rounds share nothing but a trigger, and the Red round even resets a paid ladder, so one set of free spins can claim the same jackpot twice. The weakness is the floor. The reels themselves never become interesting, and with the MEGA at 5,000x the bet as the only fixed target, the base game leans entirely on the collection to justify the time.
Collectors and jackpot hunters will feel right at home in these stands; the slow build genuinely rewards the patience. Anyone who needs the spinning itself to carry a session will find the arena quieter than the banners promise, and this won’t be the game that changes their mind.

Is Action Boost Gladiator high volatility?
Yes, it’s a high volatility slot, so wins tend to be larger but less frequent than on lower-variance games. -
How do you trigger the free spins in Action Boost Gladiator?
Each of the three coin colours feeds a matching bag above the reels. Whenever one or more coins appear, there’s a chance the Action Boost Free Spins fire, and the mix of colours collected decides which boost is awarded. -
What does the Flag Spin feature do?
Trophy Coins collect to the trophy, and each one carries a chance of triggering a Flag Spin. All flags activate for that spin, and any coins landing on flags trigger the free spins. On top of that, the spin itself can pay out any of the four jackpots. -
How do the jackpots work in Action Boost Gladiator?
