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 the feature and may receive multiplier boosts. A re-spin can lead to Free Spins, where the Wild changes into 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 are associated with wealth, and the fish guide the journey across the river towards the legendary dragon. Passing through the dragon gate is portrayed as a path to prosperity.
Graphics, sound and animation
Spearhead Studios brings crisp graphics and detailed imagery to this release. Flowers with a sketch-like look form the backdrop. A traditional Chinese-style melody provides the soundtrack and complements the game's broader theme.

How the game plays
Koi and Dragon has a 5x3 reel layout with 243 ways to win. Its symbols include Wilds, Scatters and 11 payout symbols, 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 may pay up to 75x the bet and can trigger both the re-spin and Free Spins feature. During Free Spins, Cash symbols can be worth up to 5x, while the re-spin feature offers a 5,000x jackpot chance as well as more Cash symbols.

Bonus Rounds and Free Spins
Re-Spin: Landing 2 koi Scatter symbols triggers 1 re-spin. All regular symbols are removed, leaving the koi Scatters in place. The Scatters that started 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 feature, the dragon Wild also acts as a Scatter. Moon symbols display cash values of 1x, 2x, 3x, 4x or 5x the bet, and each one that lands awards its shown value. Land 2 Scatters to trigger the re-spin feature and get a chance to win extra 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: Collecting 17 Moons during Dragon Gate awards the Major jackpot worth 100x. Collecting 36 Moon symbols awards the Grand jackpot worth 5,000x.
