Action Boost Gladiator Slot Review

Slot Details

Action Boost Gladiator is an online slot, developed by SpinPlay Games, powered by Microgaming online casinos, released in August 2023.

Themed after the gladiators of Rome, this online slot has an unusual design, consisting of two parts, a flag section and the regular gameboard, where players will have a chance to spin the reels for a max prize of up to 6,250x the bet.

Slot Design

Action Boost Gladiator online slot, has a highly unusual design, consisting of a flag section on left and a 5×4 gameboard on the right, consisting of 5 reels, 4 rows and 20 fixed paylines, that during specific free spins extend to 40 paylines with 6 rows.

The slot’s RTP is 96.27% and its variance is set to HIGH.

The minimum bet per spin starts from 0.20$, while the maximum bet per spin reaches 40.00$, making the slot ideal for a wide range of players.

SpinPlay Games still prefer this method of selecting a bet, proving only a + and – buttons and plenty of clicking in order to select the desired amount.

However we discovered a while ago a way to make things easier and that is from the Autoplay option which is nested here above the Spin button, when you click on the + arrow.

This menu allows you to use a slider in order to select your desired bet, and it will persist even if you close the menu with the X on the left without starting the Autoplay spins.

The quick spins option is also nested in that area, while the menu on the bottom right has a payline legend and a speaker icon for sound on/off.

Sadly the sounds and music are bundled up, and though the dramatic epic music is nice, it can get overwhelming real fast.

The symbols are all in 3D, very well done, the animations are also top notch, we have no remarks in the visual department at all.

Slot Features

  • Wilds: Wilds in this online slot are the Coliseum symbol, substituting for all symbols but bonus symbols.

  • Flag Spin Feature: Whenever you land a Trophy Coin symbol, there’s a chance to trigger the Flag Spin feature. All three flags spin simultaneously once and the prizes vary from different types of free spins to all 4 jackpot prizes.

During our spin, we managed to land only a purple symbol which triggered the 5 free spins with random win multiplier. This feature triggers rarely but the gold cup collecting the trophies will change depending on what your chance is. The bigger the chance the more filled the cup looks, until it gets on fire. Then you know you are really close.

  • Action Boost™ Free Spins: Every time you land a coin symbol, green, red or purple it gets collected in the corresponding pot. Each time there’s a chance to trigger the corresponding free spins. These can also be triggered from the Flag Spin feature.

  • Green Coin Action Free Spins: If the green pot triggers, you are awarded with 5 free spins. The gameboard transforms into 5×6 and your paylines go up to 40. The Green Flag will be the only one active and each gold coin landed awards one Flag spin.

The prizes differ from cash values, to symbol upgrade that would be persistent until the end of the feature. If any wild lands during the feature it will nudge to fill the whole reel.

  • Red Coin Action Free Spins: When this feature triggers from the red pot, 10 free spins are awarded. The 4 jackpots become active, as well as the red flag. Any gold coin that lands can contain a shield, a cash value or a flag spin.

Landing a shield will go towards the corresponding jackpot, depending on its color: green for Mini, blue for Minor, purple for Major and red for Mega. The flag spin can award shield, cash value or a jackpot boost. In our trigger we managed to get the Major jackpot boost, which went from 500x to 625.50x

  • Purple Coin Action Free Spins: When this feature is triggered from the purple pot, 5 free spins are awarded where a random multiplier between 2x, 3x and 5x is awarded on each spin. Gold coins that land during the free spins can award a flag spin, cash prizes or +1 and +2 free spins.

The flag spins contain cash prizes, as well as +1, +2 and +3 free spins.

  • Multiple Coins Action Free Spins: It is possible to trigger multiple coins at the same time and have combination of the features offered. This is exactly like the Power Combo slots we have reviewed like: Atlantis Power Combo Slot and Eggz! Power Combo Slot. If the red coin is one of those triggered 10 free spins are awarded, otherwise 5. The win multipliers apply to cash prizes only and not jackpots.

In this screen we managed to get red and purple coins, so we received 10 free spins and random win multipliers. Because of the total amount of free spins and some lucrative 5x multipliers our payout was 132x.


Action Boost Gladiator slot is a lot like the Power Combo slots we had reviewed last month.

The slot offers different types of free spins triggers, which can also be combined for multiple features at once.

In addition the slot offers a flag feature, which allows you to trigger a jackpot or different combinations of free spins.

Excluding minor quality of life UI remarks, we enjoyed the slot for hours, and it has been released now in Yukon Gold Casino.
