Charm of the Dragon Slot Review

Charm of the Dragon is a ways-pays dragon-hoard slot from Bullshark Games, released on 22 July 2025 and built and distributed on Hacksaw Gaming's OpenRGS platform. The headline figures are a default RTP of 96.36%, a hit frequency of 31.42%, a maximum win of 10,000x the stake and a volatility rating of 4 out of 5 on the studio's own scale. The grid starts at 5x3 and can grow to 5x6, which moves the ways count from 243 up to 7,776.

The demo above runs the studio's free-play build with a play-money balance, so you can work through the feature set, the multiplier ladder and the reel expansions without risking anything. Treat it as a mechanics tutorial rather than a sample of long-run behaviour: a few hundred demo spins tells you almost nothing about a game whose bonus arrives roughly once in 268 spins. The game is not available to UK players — the studio's approvals list covers Malta, Curacao, Denmark, Latvia, Spain, the Netherlands, Ontario, Romania, Greece, Georgia, Portugal, Colombia, Buenos Aires Province and Brazil, but not the UK, Sweden, Germany or Italy. 18+ only.

The core loop is simple to describe and slightly unusual in how it compounds. You spin a five-reel grid that is three rows deep by default, paying left to right in ways. Any winning combination does two things: it pays, and it triggers a booster. That booster either pushes the Global Multiplier Ladder up a step or adds a row to the grid, after which fresh symbols drop in immediately and the win is re-evaluated. So a modest three-of-a-kind on the opening drop can snowball into a four-row or five-row board with a 3x or 4x global multiplier sitting on top of it before the spin resolves.

Crucially, in the base game the ladder is progressive within a spin's chain of extra cascades but resets with every new spin. That is the single most important structural fact here. You are not banking anything between spins in the base game; each spin is a self-contained attempt to build a chain. Chains that die on the second or third step produce the small, frequent wins that make up the bulk of that 31.42% hit rate, and the rare chains that keep going are where the base-game upside lives.

Global Multiplier Ladder

The ladder runs 1x, 2x, 3x, 4x, 5x, 6x, 7x, 8x, 9x, 10x, 12x, 15x, 20x, 25x, 50x, then 100x. It starts at 1x. A booster usually moves it one step, occasionally several at once, and when multiple steps are awarded the move is randomised up to the maximum. The current value applies to all wins at calculation time. Note the spacing: the first ten steps are linear, then the gaps widen sharply. Reaching 10x is a realistic good outcome; the 25x-to-100x stretch at the top is where the 10,000x ceiling is actually manufactured, and it requires a chain length that the base game will almost never produce.

Expanding Reels

Each expansion booster adds a row, taking ways from 243 to 7,776 across the full range. This is a hit-rate amplifier rather than a pure multiplier: more rows means more ways, which means the next drop is far more likely to connect and keep the chain alive. The interaction between the two boosters is what gives the game its shape — expansion feeds the chain, the ladder monetises it.

Free spins, Sticky Mystery symbols and the selection bonus

In Free Spins the ladder is progressive across spins rather than resetting, and its starting value is set by the selection bonus result. That is a different game entirely from the base mode: instead of rebuilding from 1x every spin, you are compounding. Sticky Mystery symbols can land on reels 2, 3 and 4 and reveal matching symbol types, which pairs well with a wide, expanded grid. All features are progressive during Free Spins, which is the studio's way of saying the bonus is where the distribution's right tail lives.

The default build returns 96.36%, which is the top of Bullshark's current range and a genuinely competitive figure. The game also ships in a 94.33% version, and the operator chooses which one to run. That is a two-point gap and it matters far more than any feature on this list — always open the game's info screen at your casino and confirm the RTP before you stake anything.

A 31.42% hit rate means roughly one spin in three returns something, but with a ways game of this design most of those returns are sub-stake dust from a one-step chain. The bonus frequency is the number to plan around: 1 in 268.4 spins for any bonus in the base game, broken down as 1 in 286.6 for Vault of Riches and 1 in 4,213.8 for Eternal Fortune. In plain terms, at 300 spins an hour you would average about one bonus per hour, and Eternal Fortune is effectively a lottery ticket you should not budget for — expect to see Vault of Riches many times over before it appears.

If you use BonusHunt FeatureSpins, any bonus arrives 1 in 48.3, Vault of Riches 1 in 51.4 and Eternal Fortune 1 in 812.9. The feature RTPs are tightly clustered: BonusHunt FeatureSpins 96.20%, Charming FeatureSpins 96.31%, Vault of Riches 96.37% and Eternal Fortune 96.33%. Only BonusHunt FeatureSpins sits meaningfully below the base figure, so the buys are fairly priced by current standards rather than punitive.

With volatility at 4 of 5, a 10,000x ceiling and a bonus roughly every 268 spins, bankroll sizing should assume dry stretches of several hundred spins. A practical unit is a stake small enough that 600 base spins is affordable, which for most players means dropping a tier below their usual bet.

It suits players who like a visible build mechanic — watching the ladder climb and the grid grow gives the base game something to do between bonuses, which matters a lot at a 268-spin bonus cadence. It also suits anyone who prioritises headline RTP, provided they verify the version. Buy-feature players get a reasonable deal here too.

Skip it if you want a steady grind: a third of spins paying sounds generous but the payouts are heavily weighted towards tiny chain-of-one returns. Skip it if 10,000x looks thin to you — several Bullshark titles reach 12,000x or more. And if your casino runs the 94.33% build, there are better uses of your bankroll.

Charm of the Dragon is a well-constructed ways game with an honest default RTP, a clean compounding mechanic and sensibly priced feature buys. The maths holds together: boosters raise both ways and multiplier, free spins switch the ladder from resetting to progressive, and the distribution is clearly engineered around the bonus rather than the base game. The caveats are real — a 94.33% alternative build, a 10,000x ceiling that is modest for the studio, an Eternal Fortune trigger at 1 in 4,213.8 that most players will never see in the base game, and no access for UK players. Solid, with those caveats stated plainly.
