Kings of Crystals II Power Combo (All41 Studios) – Review & Demo Play

Kings of Crystals II Power Combo Slot Review

The Power Combo mechanic returns in Kings of Crystals II Power Combo, giving a sequel to the original three-feature slot a fresh push. The setup mixes three coloured crystals with free spins on an expanded grid, stacking wild reels, a line win multiplier, and fixed jackpots. It feels like a deluxe reskin with a Medieval great hall vibe and three ruling Kings overseeing the reels. I found the package tidy, with balanced gameplay, clear triggers, and solid payout potential tied to the crystal that launches the round.

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

Base play uses a 5x4 grid with 40 lines, paying left to right. When free spins trigger, the grid expands to 5x6 with 60 paylines. The action sits in a throne room where three Kings front the paytable and the crystal counters sit above the reels. Visuals are clean with stacked symbols and tidy animations that switch up during features. It’s a familiar series look that suits the Power Combo format and keeps the focus on the three-modifier bonus play.

Symbol values mirror the theme. The Green King pays 0.50x, 1x, and 5x the bet for 3, 4, or 5 of a kind. Blue King and Red King award 0.30x, 0.50x, and 2.50x, matching premium items like Glove Armour and Goblet. A, K, Q pay 0.10x to 0.80x; J, 10, 9 pay 0.10x to 0.70x. Wilds land stacked on reels 2–5 and substitute without a direct pay, which helps stretch stacked hits across lines when the grid expands.

How to Play Kings of Crystals II Power Combo Online Slot

Wins form by landing three or more matching symbols on adjacent positions from the leftmost reel. Stake is set via the coin stack button; autoplay sits under the spin, and a small video icon replays the three Kings’ story. Keep an eye on the red, blue, and green Scatter crystals that can trigger free spins. Base play runs on 40 paylines, but the bonus upgrades to 60 lines on a 5x6 layout, where stacked symbols and wilds have more room to connect.

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

Three Scatter colours carry the Power Combo. Any collection can trigger six free spins, and you can launch with one, two, or all three modifiers active. The bonus always plays on an expanded 5x6 grid with 60 paylines. Crystal collections feed Power Pots in base play, enhancing the respective modifier for the next bonus. After a feature ends, its counter resets. Hourglass symbols are active during free spins and add +1 spin to the remaining total every time they land.

Red Scatter triggers Wild Power Free Spins. The Power Pot can raise the number of Wild Reels up to 15. On each free spin, up to three Wild Reels may appear until that stock is used. With stacked symbols and added wild coverage on a 60-line grid, line connections jump, especially if you’ve combined modifiers. After the feature finishes, the base counter for Wild Reels resets to three, and any future red crystal collections start building again.

Blue Scatter activates Multiplier Power Free Spins, applying a collected line win multiplier up to x15 on all line wins. Green Scatter triggers Jackpot Power with Golden Coins. Coins reveal coloured tokens or 1x–10x cash prizes. Collect tokens to land fixed jackpots once per round: Mini (4 blue), Minor (5 green), Major (5 purple), Grand (5 red). Sizes start at 10x, 20x, 250x, and 10,000x. Mini, Minor, and Major can grow to 35x, 70x, and 500x via collections; Grand stays fixed.

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

I moved from a few demo spins to £2 autoplay. The first stretch was quiet, with only small line hits across stacked royals. On spin 48, a green crystal triggered and coins flowed fast. Tokens dropped early for a Mini, then a tidy 8x cash coin. An Hourglass added +1 spin, landing another coin cluster before the last spin. The round wrapped well ahead of the start balance, helped by the 60-line layout catching extra stacked matches.

Later, a red-triggered bonus arrived with a decent Wild Reel stock. Two wild columns hit back-to-back and pulled in a mid-range line cluster, though the final tally sat behind the green round. Across 150 spins, volatility felt more middle-of-the-road than spiky, with most of the value in the features. I didn’t see a blue-only round in that set, but the line win multiplier is the one I want next, ideally paired with wild reels.

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

Kings of Crystals II Power Combo comes with a highest RTP of 96.20%, with alternatives at 94.20% and 92.20%. The hit frequency sits at 39.84%, and volatility is medium, which matched my session feel. The maximum win reaches 12,500x the bet, with stakes from €0.20 to €25 per spin. Fixed jackpots headline with a 10,000x Grand, while stacked symbols, Wild Reels, and the line multiplier drive most non-jackpot peaks on the expanded 60-line free spins grid.

Kings of Crystals II Power Combo Slot Verdict and Recommended Games

If you like Power Combo slots built around three clear modifiers, this sequel lands well. The expanded grid gives stacked symbols room to work, the line multiplier adds proper punch, and Jackpot Power offers a second route to a headline hit. Counter build-up in base play sets a neat cadence, and Hourglass extensions make the bonus feel alive without dragging.

It is a deluxe reskin, but the balance shift to medium volatility makes sense. The ranging RTP is worth checking in your lobby. As a package, Kings of Crystals II Power Combo is a tidy step up on the theme, with the best returns coming from combo-triggered rounds. If you want a reference point, spin the original Kings of Crystals, then come back and power up the sequel.
