Kings of Crystals II Power Combo Slot Review

Kings of Crystals II Power Combo Slot Review

Kings of Crystals II Power Combo is a follow-up to the 2022 Kings of Crystals slot, and All For One Studios has given it the full Power Combo treatment. The game takes you to a Medieval great hall where three kings sit behind the reels, each linked to a coloured crystal and a different free spins power. On the surface it feels familiar, yet the new combo system gives the sequel a fresher, more progressive angle.

From my first session, Kings of Crystals II Power Combo came across as a classic feature-chaser. The base game keeps you ticking over with stacked symbols and plenty of wilds, while the real punch sits in the three Power Pots and their linked free spins modes. It still looks and sounds like a premium fantasy slot, but the focus is clearly on building those modifiers and hunting one big, explosive bonus round.

Kings of Crystals II Power Combo Online Slot Layout, Theme and Setup

The Kings of Crystals II Power Combo slot runs on a 5x4 grid with 40 fixed paylines in the base game, paying from left to right from the far-left reel. The action plays out in a throne room, with banners, braziers and animated kings framing the reels. On the left you see the Mini, Minor, Major and Grand jackpots, while the top of the screen shows the three crystal Power Pots that track your feature progress. The whole setup runs smoothly on mobile thanks to HTML5.

How to Play Kings of Crystals II Power Combo Online Slot

Getting started with Kings of Crystals II Power Combo is simple enough. You set your stake with the coin stack button, choosing between 0.20 and 25 per spin, then hit the main spin icon or set up autoplay. Wins land when three or more matching symbols fall on one of the 40 lines, starting from reel one. When free spins trigger, the grid expands to 5x6 with 60 paylines, using the same basic pay rules but with your collected modifiers applied.

Symbol-wise, the Green King is the premium picture, paying 0.50x, 1x and 5x your bet for three, four and five of a kind. The Blue and Red Kings share a paytable with the Goblet and Glove, at 0.30x, 0.50x and 2.50x for three to five. Royals A and K and Q sit in the middle, with J, 10 and 9 as low pays from 0.10x up to 0.80x. All symbols, including wilds, can land stacked, while wilds appear only on reels two to five and substitute without any line wins of their own.

Kings of Crystals II Power Combo Online Slot Free Spins, Bonus Features, & Bonus Buy

The heart of Kings of Crystals II Power Combo lies in the three coloured crystal scatters. Red, blue and green crystals land on the reels and feed into their own Power Pots above the grid. Any crystal in view can randomly trigger six free spins, and the mode you get depends on which crystals launch the round. One crystal gives you a single feature, while two or three at once will combine their powers. During all free spins, the layout switches to 5x6 with 60 paylines, and Hourglass symbols add +1 extra spin each.

Red crystals control Wild Power Free Spins. As you collect them in the base game, they increase a counter for wild reels, which can climb as high as 15 stored wild reels. In the bonus, up to three of those wild reels can appear on a single spin until you have used the full stock. After the feature ends, the red counter drops back to three stored wild reels. Blue crystals fuel the Multiplier Power Free Spins, where each collection can raise a line win multiplier up to x15, applied to every payline hit during that round.

Green crystals are all about Jackpot Power. Each one can randomly increase the Mini, Minor or Major jackpots, with caps of 35x, 70x and 500x your stake, while the Grand stays fixed at 10,000x. In the green free spins mode, Golden Coins land with either cash prizes of 1x to 10x bet or coloured tokens. Collect four blue tokens for the Mini, five green for the Minor, five purple for the Major or five red for the Grand. Each jackpot can drop once per feature, but you can land more than one in a single bonus. There is no bonus buy option here, so you have to trigger everything through natural play.

My Experience Playing the Kings of Crystals II Power Combo Slot for Real Money

I always like running a slot in demo for a few minutes, then switching to real money once I have seen the flow. With Kings of Crystals II Power Combo I settled on 1 unit per spin and set 50 auto spins. The first part of the session felt quite flat, with stacked kings landing often but rarely lining up, and most of my wins sitting between 2x and 6x. It matched the feel of a Power Combo game that can hold back while it builds its features.

Things changed once I landed a three-scatter trigger with red and green crystals active. The bonus started on the 5x6 grid with a couple of early wild reels and a handful of Golden Coins. I grabbed the Mini at 20x, had a few small cash coins, then hit a screen with two wild reels and stacked Green Kings for around 40x. By the end of the round I had just over 90x my stake from that feature, which was enough to pull the session into profit despite the slow start.

Kings of Crystals II Power Combo Slot RTP, Maximum Payout & Volatility

On the numbers side, Kings of Crystals II Power Combo comes with a variable RTP, with main settings of 96.20%, 94.20% and 92.20%. Most decent sites run the 96.20% model, so I always check the info screen before spinning. The hit rate sits at a chunky 39.84%, while volatility is officially rated as medium, though it can feel a touch higher during cold patches. The Grand jackpot pays 10,000x your bet, and the overall max exposure climbs to around 12,500x when you factor in strong line hits with multipliers. Stakes range from 0.20 to 25 per spin, and there is no progressive prize pool attached.

Kings of Crystals II Power Combo Slot Verdict and Recommended Games

Kings of Crystals II Power Combo will suit anyone who enjoys building towards feature-heavy free spins rather than constant small bonuses. The three Power Pots give you clear goals in the base game, and I like how different the red, blue and green modes feel. The expanded 5x6 grid, stacked wild reels and chance to combine modifiers mean the slot can throw out some very tasty patterns when things line up.

On the downside, symbol values are on the low side, so without multipliers or wild reels your line wins rarely feel exciting. It is also a reskin of the first Kings of Crystals in many ways, so if you played that a lot you may get a sense of déjà vu. Even so, the more balanced volatility and higher overall potential make this sequel the version I would pick up when I want a fantasy Power Combo session with decent long-term prospects.
