Game mechanics
Wins form on 28 ways across a 5x3 grid — matching symbols on adjacent reels from the left, rather than along fixed paylines. The theme is a tranquil koi pond, but the base game's real event is a random Mega Symbol: reels two, three and four merge into a single 3x3 symbol, which can complete many ways at once.
Three, four or five scatters award 5, 8 or 18 free spins, and during the round a Mega Symbol lands on every single spin. A Super Bet option doubles the stake to make the bonus trigger more often, and a Buy Feature opens the free spins directly. Listed at 96.84% RTP with medium volatility and a top win of 1,682x the bet.
