Koi and Dragon Online Slot Review
Koi and Dragon offers non-progressive jackpot prizes through its Dragon Gate feature, with a potential value of 5,000x. Cash symbols appear during this feature and may receive multiplier boosts. A re-spin can lead to free spins, where the Wild becomes a special scatter symbol and cash symbols can pay from any reel position.
Theme and Storyline
A river full of koi carp flows beneath a mountain range. In Chinese culture, koi carp are linked with wealth, and the fish guide the journey across the river toward the legendary dragon. Passing through the dragon gate is depicted as a path to prosperity.
Graphics, Sound, and Animation
Spearhead Studios pairs crisp graphics with detailed imagery in this release. Flowers, rendered in a sketch-like style, fill the backdrop. A traditional Chinese-style tune provides the soundtrack and complements the game's broader theme.

How the Game Plays
Koi and Dragon uses a 5x3 reel layout with 243 ways to win. Its symbols include Wilds, Scatters, and 11 symbols with payout values, including the Scatter symbols. The dragon is Wild, substitutes for every symbol except the Scatter, and can appear on reels 2, 3, and 4. The koi carp Scatter can pay up to 75x the bet and trigger both the re-spin and Free Spins feature. During Free Spins, cash symbols may be worth up to 5x, while the re-spin feature offers a chance at a 5,000x jackpot along with additional cash symbols.
Spin bet multipliers for 2, 3, 4, or 5 matching symbols from left to right on a payline:
- Koi Scatter – 1x, 5x, 10x, 100x
- Geisha – 0.83x, 3.33x, 8.33x
- Bird – 0.50x, 1.66x, 5x
- Flower – 0.50x, 1.66x, 5x
- Lantern – 0.33x, 0.66x, 3.33x
- A, K, Q, J – 0.16x, 0.33x, 1.66x
- 9 – 0.06x, 0.16x, 0.33x, 1.66x

Bonus Rounds and Free Spins
Re-Spin: Landing 2 koi Scatter symbols triggers 1 re-spin. The re-spin removes all regular symbols, leaving the koi Scatters in place. The Scatters that triggered the feature stay where they landed while the other reels spin again. If the re-spin round ends with 3, 4, or 5 koi Scatters, Free Spins are triggered.
Free Spins: Landing 3, 4, or 5 koi Scatters during the re-spin round awards 8, 15, or 30 Free Spins, respectively. Throughout the Free Spins round, the dragon Wild also functions as a Scatter. Moon symbols show cash values of 1x, 2x, 3x, 4x, or 5x the bet, and each Moon that lands awards its displayed value. Land 2 Scatters to trigger the re-spin feature and get a chance at more spins.
Dragon Gate: Landing 3 or more Moon symbols triggers the Dragon Gate feature. Only Moon and box symbols can land during this round. Moon symbols carry values of 1x, 2x, 3x, 4x, and 5x, while multipliers on reels 4 and 5 increase all prizes. Collect 3 or more Moon symbols to enter the 2nd game. Collect 9 or more to enter the 3rd game. Collect 16 or more to enter the 4th game. Collect 25 Moon symbols to enter the 5th game.
Koi and Dragon Jackpot: Collect 17 moons during Dragon Gate to win the Major jackpot, valued at 100x. The Grand jackpot is worth 5,000x and is awarded for 36 moon symbols.
