Action Boost SpinUP Gladiator Slot Review

Slot Details

Action Boost SpinUP Gladiator is an online slot, developed by developed by SpinPlay Games, powered by Apricot online casinos, scheduled to be released on April 22nd 2025.

A year and a half after the release of the original Action Boost Gladiator Slot, the studio is bringing up this sequel.

Though the slot is more than a month away from an official release, Yukon Gold Casino has it exclusively in their Early Release section.

Slot Data

Slot Design

Action Boost SpinUP Gladiator has a very unusual gameboard like the original, consisting of a flag section on the left and a 5×4 gameboard on the right. The gameboard has 5 reels, 4 rows and 20 fixed paylines, which in the green free spins turn into 40 paylines.

The slot’s RTP is 96.49%, the volatility is set to HIGH and the hit rate is 33.57%.

The minimum bet per spin starts from 0.20$, while the maximum bet reaches 50.00$, with the max prize being capped at 5,000x the bet.

The studio has changed to this bet menu style for a while now, which we totaly love as it allows the player to select their desired wager with a simple click.

While the slot has no real settings menu, it has all of the necessary options scattered around other menus like the autoplay menu.

The player can find the Quick Spins option here on the bottom and can toggle it ON, and then close the menu without starting autoplay. There’s also a sound menu with volume adjusters and options for background music and sounds which is very convinient.

Overall the slot has kept nearly identical gameboard, symbols, music and features, which begs the question what exactly is the purpose of the slot.

Slot Features

• Wilds: The wilds in this slot are the colosseum symbols which don’t really show up much during base game. They do show up on the green free spins feature a lot and expand as well.

During our testing, we didn’t find these symbols good enough to contribute with any significant winnings. They did contribute to most winnings during the green free spins feature.

Here any wild that lands gets expanded and this is where decent winnings form. The paylines also increase from 20 to 40 which also helps.

• Flag Feature: This feature triggers randomly by collecting the gladiator head symbols. In the original slot, this feature could only grant you jackpots and prizes, but now it will trigger free spins or free spins with upgrades.

This feature is a very rare feature that will show up very very rarely to the point that you might not even see it in your gaming session.

• Free Spins: Whenever one of the three coins lands on the reels and it’s collected to the corresponding pot, free spins with that particular feature can be triggered. The green pot triggers a feature where the board expands to 5×6 with 40 paylines and additional wilds which will extend.

Landing a flag symbol will either give cash prizes, or swap a specific symbol for the highest paying symbol.

Landing the red coin will trigger the jackpot feature, where landing the corresponding color will be contribued to the jackpot.

There’s a special feature in this version of the slot where the maximum symbols needed for the jackpots is shortened by 1. There are also jackpot boosts and cash prizes on the flag on the left. The original values of the jackpots are Mini 5x, Minor 10x, Major 25x, Maxi 250x, MEGA 5,000x. These values can be increased by landing the boost options on the flag.

The purple free spins trigger offers a multiplier starting from 2x, and can be upgraded to 5x. During this feature, the flag offers extra spins and the symbols that land can also offer extra spins. On this trigger we managed to get to 19 free spins from the original 10.

Verdict

Action Boost SpinUP Gladiator is the sequel of the original slot that came out back in 2023.

On first look, you can’t really see anything different, as the UI, and the symbols and the music look the same.

Upon testing the slot, we found out that the flag feature is different and now triggers free spins, and free spins with upgrades.

The features are nearly identical, excluding the multiplier one, where the multipliers are not random anymore and can be upgraded.

The jackpot free spins can trigger an upgrade where you need 1 less symbol for each jackpot to be awarded which is a great boost.

The improvements are decent, but the flag feature is still quite too rare to even matter, and that’s something we didn’t like at all.

The slot is currently available in Yukon Gold Casino, so anyone wanting to test the game ahead of time can do so.
