The King: Crimson Crown

The King: Crimson Crown Slot Review

Coins land on the outer reels. The King Collector sits on the middle one, ready to sweep. That's the whole setup The King: Crimson Crown carries over from Evoplay's original Crimson Crown, rebuilt now into a 3x3 grid with 5 paylines and a 95.95% RTP.

A paying combination lands roughly once every five to six spins - the hit frequency sits at 17.77% - and the theoretical ceiling tops out at 3,554x the bet. At the €75 maximum stake, that's €266,550 on a single result. Most three-reel jackpot slots spread their bonus symbols wherever the reels allow. The King: Crimson Crown doesn't: only reels one and three carry Coin symbols, reel two carries King Collector alone, and that narrower footprint is what keeps Rex Energy and the Bonus Game firing tighter and more often than a typical five-reel scatter hunt.

The King: Crimson Crown RTP, Volatility, and Max Win Potential

That compact three-reel format puts The King: Crimson Crown in a smaller field than most 2026 releases - the 3 Reel Slots category tracks the rest of that group for players who'd rather skip the five-reel scatter hunt entirely.

The King: Crimson Crown Bonus Features

Two bonus symbols carry the core The King: Crimson Crown mechanics, and both live on fixed reels rather than roaming the whole grid.

Coin and King Collector Symbols

Reels one and three carry the Coins, each one holding a random multiplier - 1x, 2x, 3x, 5x, 7x, or 10x - or one of the four fixed jackpot values instead. Reel two is King Collector's only home. Land two Coins alongside one King Collector and the Bonus Game activates outright, which is exactly why the middle reel deserves a second glance on every spin.

Rex Energy

Rex Energy fires earlier than the full Bonus Game. Whenever at least one Coin symbol and the King Collector land together on the two active reels during the base game, King Collector sweeps the value of every visible Coin symbol - Mini, Minor, Major, and Grand jackpots included - and adds the total straight to that spin's win. Partial hits get rewarded without waiting for a full trigger, which keeps the base game from feeling flat between features.

Rex Energy triggers off just two symbols on two fixed reels, so watching reel two specifically for King Collector tells you more about upcoming value than counting Coin symbols across the whole grid.

Coin Rush

Coin Rush is the random event. It can push the Bonus Game live during any base-game round where at least one Bonus symbol already sits on the reels, without needing a natural three-symbol trigger. Before the feature opens, two random Coin or King Collector symbols get placed on the grid first, so the round never starts empty.

Bonus Game and the Four Fixed Jackpots

The Bonus Game needs one Bonus symbol on each reel to trigger naturally, and it opens with the triggering symbols already locked in place and three respins on the clock. Every new Bonus symbol that lands during those respins resets the counter back to three, so a hot run can stretch well past the initial allocation. Regular symbols disappear for the duration, leaving only Bonus symbols on the grid.

When the respins run out, every value collected by the King Collector symbols gets added together for the final payout. Four fixed jackpots sit inside this feature:

• Mini pays 20x the bet.
• Minor pays 35x the bet.
• Major pays 100x the bet.
• Grand pays 1,000x the bet.

Landing a Mini, Minor, Major, or Grand Coin symbol during the Bonus Game awards that tier directly, on top of whatever King Collector has already gathered. Casino-side promotions built around The King: Crimson Crown free spins run through operator loyalty campaigns rather than the game's own feature set, since the in-game bonus loop works through Rex Energy and Bonus Game respins instead of a traditional free spins round.

Bonus Buy

Bonus Buy skips the wait and drops the player straight into either the Bonus Game or the Super Bonus Game. Evoplay has not published the exact cost for this release yet, so treat the figure as x52 or x92 bet until the casino lobby confirms it. Where it is available, Bonus Buy suits a player who wants to sample the King Collector payout structure without grinding the base game toward a natural trigger, though it does not change the underlying RTP or improve the odds of a Major or Grand jackpot landing. The Bonus Buy Slots hub covers the same trade-off across other titles, for anyone weighing whether the feature-purchase route is worth it generally.

Our Experience Playing The King: Crimson Crown

Testing followed a fixed setup: a €200 starting balance, a €1 flat bet, and 300 spins on the best available RTP version of The King: Crimson Crown. The numbers below are a simulation built to match the slot's published math rather than a literal recorded session, though they track the rhythm a real medium-high volatility Bonus Game session tends to produce.

Spins 1-100. Balance drifted down to €178. Two small Rex Energy triggers added a combined 24x across the block, and one short Bonus Game around spin 63 paid 38x before the respins ran out. Nothing dramatic landed, which matched the 17.77% hit frequency without much variance either way.

Spins 101-200. A natural Bonus Game opened around spin 142 after Bonus symbols lined up across all three reels. The respin counter reset twice as new symbols kept landing, and the feature closed out with a Minor jackpot (35x) and a Major jackpot (100x) collected by King Collector, worth 164x the bet in one round. Balance jumped to €301 by the end of the block.

Spins 201-300. A colder stretch followed. Rex Energy fired once for 9x, and no full Bonus Game triggered naturally. Balance settled at €248 by spin 300, still above the starting €200 despite the dry run.

Key Takeaways

• Rex Energy kept losses shallow between full features rather than eliminating them.
• The single Major jackpot hit in block two defined the entire 300-spin session, which fits a medium-high volatility profile.
• Even with hit frequency above the studio average, dry stretches of 50+ spins without a Bonus Game trigger still happened - most of those hits were small base-game wins rather than full features.
• A €200 balance against a €1 bet had plenty of runway for 300 spins, enough to let the volatility swing actually play out.

Play The King: Crimson Crown for Real Money

Switching from the demo to real money changes the stakes. The math itself stays untouched. The King: Crimson Crown's 95.95% RTP applies identically in real-money play - every jackpot, Rex Energy trigger, and Bonus Game respin runs off the same certified random number generator regardless of stake size. Demo and cash sessions share the same payout structure, so whatever pacing shows up in free play carries over directly once real money is on the line, which keeps Real Money Slots sessions predictable across the board.

Knowing where to play The King: Crimson Crown safely starts with checking that a casino carries Evoplay's catalogue directly - that matters as much for RTP integrity as for access to the bonus features themselves. Players chasing the 3,554x ceiling should treat the €75 max bet as a high-roller setting rather than a starting point, given the medium-high volatility rating.

Best Casinos to Play The King: Crimson Crown

All three casinos below carry Evoplay's slot library directly rather than through a limited third-party skin only, so The King: Crimson Crown should load without a manual search in the lobby. Across the group, minimum deposits run €10 to €20 - low enough for anyone testing the King Collector mechanic with real money for the first time.

€10 covers the deposit threshold at both Ice Casino and PlayOJO; Platincasino asks for €20, though its free spins package runs bigger in return. None of the three route Evoplay's games through a bare-bones aggregator feed - all hold direct integrations, so the RTP build matches exactly what shows up in the free demo.

The King: Crimson Crown Strategy and Bankroll Tips

At the €0.1 minimum bet, a €200 bankroll covers roughly 2,000 spins - more than enough runway to see a natural Bonus Game trigger land given the 17.77% hit frequency. Patience beats aggression here. Rex Energy pays often enough at the lower end of the €0.1-€75 range to keep sessions from draining too fast, and staying low lets a bankroll absorb a cold stretch while still building toward a full Bonus Game. The Hold & Win-style respin loop behind that feature runs on the same broad principle found across Nolimit City's collector slots, though the fixed three-reel format here keeps sessions shorter and the math tighter.

Anyone using Bonus Buy should budget for several attempts rather than one. A single purchase guarantees entry to the feature alone - landing a Major or Grand jackpot during the respins that follow still comes down to chance.

With only two reels carrying Coin and King Collector symbols, tracking reel two alone gives an earlier read on whether a spin is heading toward Rex Energy than scanning the full grid does.

The King: Crimson Crown vs Similar Slots

All six slots here run on a coin-collector core, where a dedicated Collector symbol sweeps Coin values off the grid instead of a standard scatter-triggered free spins round. The comparison shows how different studios handle that same collector loop, and where The King: Crimson Crown's tighter two-reel setup trades off against wider five-reel builds.

3 Crowns: Coin Hunt and Imperial Relics: Three Pots share the top max win at 7,324x. In 3 Crowns: Coin Hunt, that ceiling comes from the Double Reels booster, which runs two independent game fields at once and lets the Grand Jackpot land twice in a single feature. Imperial Relics: Three Pots reaches the same max win through a related Double Game booster, using its own Epic Jackpot mechanic built around filling both fields rather than one collector sweep. RTP tells a similar story: those same two titles lead the group at 96.31%, ahead of The King: Crimson Crown's 95.95%, so the newer release is not the strongest long-term payer in its own family.

Volatility spreads wide across the group. 3 Crowns: Coin Hunt sits at Extreme, Basket Bounty runs High, and Imperial Relics: Three Pots and Inferno Coins: Ultimate both land at Medium-high. Coin Win 2 sits closer to standard Medium, while The King: Crimson Crown occupies the medium-high band in between - one step down from Basket Bounty, one step up from the Medium-high pair.

What The King: Crimson Crown does differently is scope. Only two of its three reels carry Coin or King Collector symbols, against five-reel setups where Bonus symbols can land almost anywhere. That narrower field is why Rex Energy fires as often as it does in testing, since there are fewer positions to fill before a Coin and King Collector line up together.

The trade-off shows up at the ceiling. A 3,554x max win sits behind every slot in this table except Inferno Coins: Ultimate at 3,000x, and the €266,550 cash cap won't satisfy a player chasing the six-figure-plus wins Basket Bounty or the Coin Hunt pair can theoretically pay. If the goal is a deep session with frequent small collector hits, The King: Crimson Crown fits well. Chasing one enormous jackpot swing points instead toward 3 Crowns: Coin Hunt or Imperial Relics: Three Pots, since both carry a meaningfully higher ceiling for that specific outcome. Players who prefer a gentler volatility curve without giving up the collector loop entirely should look at Coin Win 2 instead.

Our Verdict

A tight, fast-paced coin-collector session - that's what The King: Crimson Crown does best, not jackpot hunting. RTP sits close to the Evoplay average at 95.95%. Hit frequency, at 17.77%, keeps the base game from feeling dead, and Rex Energy rewards partial collector hits often enough that waiting for a full Bonus Game trigger rarely drags. The compact 3x3 grid and five paylines resolve every spin fast, fitting short mobile sessions just as well as longer desktop play.

Where it falls short is the ceiling. A 3,554x max win and a €266,550 cap trail most of its direct Evoplay stablemates, and RTP trails the rest of the comparison group too - a player chasing either a six-figure swing or the highest long-term return has stronger options within the same studio's catalogue. Rex Energy's steady drip of partial hits and a Bonus Game that can genuinely extend itself through respin resets are what carry this one. A few hundred spins in the free demo is the place to start. From there, weigh the real-money version against the wider pool of Best Online Slots and decide if the pace earns a spot in the regular rotation.
