Dragon Legend Slot by PG Soft

Most free spin triggers ask you to land scatters. This one asks you to land the right fish next to each other. A Gold Koi has to appear exactly one reel to the left of a Silver Koi, on the same row - not just anywhere on the grid, not adjacent in any direction, but specifically left-of on the same horizontal line. When it happens, the pair awards 2 free spins with a x2 multiplier on all wins. It's a narrow trigger window on 9 paylines, so the feature fires less often than traditional scatter-based bonuses, and the 2-spin award keeps each round brief.

The roulette is where the game concentrates its bigger payouts. Three Bonus symbols across reels 2, 3, and 4 open a prize wheel with 5 spins. You control how hard the wheel spins - a power gauge determines the rotation strength, though the landing position is still random within that range. The wheel contains cash prizes alongside Gold and Silver Koi tokens. Collect one of each and the wheel levels up: prize values increase, you get 2 extra spins, and the koi tokens reset. Three levels total. Level 1 has two Gold and two Silver Koi on the wheel, making a pair relatively likely. Level 2 drops to one of each with better prizes. Level 3 removes koi entirely - nothing but cash slots, highest values the game offers.

The Chinese mythology here draws on the Dragon Gate legend, where koi swimming upstream transform into dragons. Golden temple architecture sits against cliffside fog, with a lotus pond glowing beneath the reels. Gold and silver koi are the highest-paying regular symbols, and the dragon itself only appears as a Wild. Incense smoke drifts across the lower portion of the grid between spins.

Nine paylines keep the base game math straightforward. Wilds substitute for everything except the Bonus symbol. No buy bonus, no ante bet, no tumble mechanic. For a 2019 PG Soft release, the construction is deliberately minimal - two features built around koi fish positioning and a leveling roulette wheel, nothing else competing for attention.
