Our team tried the Action Boost Max Gilded Mines free play version here, on this page, to create this detailed review for the SlotsCalendar users. We suggest you do the same if you want to immerse yourself in the mining adventures along with the magic dwarf. SpinPlayGames released this video slot in June 2025. It comes with a 5-reel and 4-row grid, 20 fixed paylines, gold nuggets, and lots of fun. In this unbiased review, we will talk about all the details you might need to be part of the mining team. Who knows, maybe you will be the one to find the biggest, shiniest gem.
Theme and Design
While having a go at the Action Boost Max Gilded Mines demo, we couldn’t help but notice that the designers skillfully incorporated the gameboard into a cave, with crystal clusters around it and a miner dwarf guarding the treasures you might win. As colorful as it is, it’s also equally shiny, and we think that the design is in harmony with the chosen theme and very suggestive.
The background music and sound effects create an exciting atmosphere, motivating you to try to win the jackpot.

Wager limits
This slot comes with a flexible bet, starting from 0.2 up to 50 credits. We like to see that players can be in complete control of how much money they spend, and this game does just that.
RTP & volatility
Because we want our review to be comprehensive, we also checked the Action Boost Max Gilded Mines RTP, which is set at 96.49%. This is a good rate, considering that the average for this type of slot is around 96%. This game’s volatility is high, meaning you should not expect frequent wins, but when they do happen, they are most likely to be consistent.
Symbols
Moving forward, we want to introduce you to the symbols you will find in this video slot. The amount that each of the symbols pays depends on how high you set the bet. We set the bet to 50 credits while doing this review.
Starting with the basics, they are 9, 10, J, Q, K, and A. When we landed between 3 and 5 of the same kind, we got from 5 up to 50 credits. The themed symbols are next: the dwarf, the shovel, the pickaxe, the lantern, and the helmet. When we landed between 3 and 5 of the same kind, we got from 12.5 up to 125 credits. We noticed that the wild symbol looks like a trolley full of gold, and it can substitute for all symbols except bonus symbols. The bonus symbols are the green gem, the red gem, and the purple gem. By collecting a multitude of these gems, you can trigger the bonus round. The dwarf coin symbol, which looks like a normal gold coin with a portrait of a dwarf sculpted on it, appears only in the bonus round and combines with one of the gems' bonus features. The dwarf collects the gold nugget symbol and has a chance to trigger the pick feature.
Bonus features
To make sure we include every aspect of the game in this Action Boost Max Gilded Mines slot review, we will now present you the bonus features: 
- Pick feature: If the dwarf collects gold nuggets in the base game, this feature has a chance to trigger. Pick items can reveal credit prizes, jackpots, action boost features and upgrades, and terminate coins. This feature ends when you reveal 3 terminate coins.
- Action boost max feature: There is a chance for this feature to trigger whenever one or more gems land. Each gem color has its corresponding effect.
- Green gem - you get 10 free spins. Every dwarf coin that lands during this feature awards a bonus credit prize, an additional action boost feature, or an upgrade. You can upgrade the green action boost twice, and each upgrade adds additional wilds to the reels, 2 more rows, and 20 extra paylines.
- Red gem - you get 10 free spins. Every dwarf coin that lands during this feature awards a bonus credit prize, a jackpot hammer, an additional action boost feature, or an upgrade. You can upgrade the red action boost twice, and each upgrade reduces the number of hammers needed for each jackpot collection by 1.
- Purple gem - you get 10 free spins. Every dwarf coin that lands during this feature awards a bonus credit prize, an additional action boost feature, or an upgrade, and 1 or 2 free spins. You can upgrade the purple action boost twice, and each upgrade increases the active multiplier from 2 to 3, respectively to 5. Line wins and bonus credit prizes are multiplied by the active multiplier.
- Multiple gems - you get 10 free spins. The bonus round triggers all action boosts. The multiplier from the purple gem does not apply to jackpots. When a dwarf coin awards an additional action boost feature or upgrade, it also awards 2 extra free spins.
- Jackpots: There are a total of 5 jackpots in the game, and each needs a different number of hammers to be collected in order to win the jackpots.
- Mini - 3 green hammers
