Action Boost SpinUP Knights Ascension Slot Review
Slot Details
Action Boost SpinUP Knights Ascension is an online slot, developed by SpinPlay Games, powered by Apricot online casinos, scheduled to be released on April 15th 2026.
If the name sounds familiar that’s because I’ve already reviewed a similar one from the same studio called Action Boost SpinUP Gladiator, with pretty much the same technical specifications.
This one however has higher max win of up to 6,250x, and a bit milder volatility set to MEDIUM-HIGH.
Though the slot is around a month way from an official release, Yukon Gold Casino has it exclusively in early access on their site.
Slot Design
Action Boost SpinUP Knights Ascension has a slightly bigger 5/4 gameboard with 5 reels 4 rows and 20 fixed paylines.
The slot’s RTP is 96.49%, the volatility is set to MEDIUM-HIGH and the hit rate is 33.57%.
The minimum bet per spin starts from 0.20$, while the maximum bet per spin reaches 40.00$, with the max prize capped at 6,250x.
A while ago, the studio made the decision to switch their bet menu to a one click menu and we loved it: clean and quick allowing the players to select their desired wager right away with a single press.
However the settings menu only has a hotkey option with the rest of the options in the autoplay menu.
In addition there’s a separate sound menu with options to mute music or sounds individually and there are volume sliders as well, which is just ideal.
Overall the UI looks identical to the rest of the slots from the Action Boost SpinUP series with the notorious 3 flags on the left side of the gameboard.
Slot Features
- Wilds: The wilds in this slot substitute for all symbols but gold coin symbols.
Unlike the Action Boost SlotUp Gladiator where the Wilds barely showed in base game, they show up a LOT here and often contribute to small and medium size winnings usually up to 7x.
- Flag Feature: Whenever a gold coin appears there’s a chance for the flag feature to trigger.
All flags are active when the feature triggers, and a single flag spin is awarded. When one or more coins land here, the free spins are triggered. In this case we triggered free spins with expansion where the gameboard becomes 5×6 and the shield icon unlocking the collection of jackpots: Mini 5x, Minor 10x, Major 25x, Maxi 250x, and MEGA 5,000x.
- Free Spins: Any time a gold coin lands, there’s a chance for the free spins feature to trigger with 1, 2 or 3 total perks.
The different perks are, a bigger gameboard with 6 rows and nudging wilds which will fill the whole reel. The shield perk allows for collection of jackpots and the multiplier perk randomly applies a multiplier between 2x 3x and 5x.
All of these features were present in the previous slots so anyone that has played them would be quite familiar with everything here. Extra spins up to 3 are still offered so again something that was seen before as well.
Verdict
Is Action Boost SpinUP Knights Ascension worth your time? If you have played the previous slots, you wouldn’t see anything different here so NO.
However if you just want a visual change or you have never ever played slots from these series, then definitely this one is a must try.
Several different jackpots, engaging free spins, multiple perks and decent max win.
In addition the volatility was slightly lowered so perhaps that might appeal to more people, but doesn’t feel like enough for those already enjoying the Gladiator one.
