How to play Koi Harmony
The one genuinely new seasonal wrinkle is a pumpkin symbol. It can land during free spins to award mid-bonus upgrades, layered on top of the ante bet and feature-buy options already familiar across the range. For an experienced Big Bass player, the proposition is deliberately recognizable rather than reinvented.
The value of this release lies in what it says about franchise strategy. The Big Bass series has become one of Pragmatic Play’s most reliable engines, and reskinning a proven math model with seasonal theming is a low-risk way to keep the brand visible during a commercially significant window.
Halloween is a natural peg for that approach. It gives operators a topical, franchise-branded title to feature in October promotions without asking players to learn a new system. The friendly Count Dracula fisherman and trick-or-treat trimmings supply the seasonal hook while the underlying fish-collection loop does the heavy lifting.
What is Koi Harmony?
Stella David, Entain’s CEO, called for the government to move ahead with the ban immediately, arguing clubs were already aware of the planned changes.
“Premier League clubs that have struck new deals with unlicensed gambling operators knew the risks,” she said. “The government made clear in February that it would bring in a ban and it should do so immediately: even if that means clubs ordering new kit mid-season.
“Inconvenience is not an excuse for inaction.”
About Koi Harmony
In January, Polymarket and Dow Jones announced an agreement that paved the way for event contract data to appear on various Dow Jones sites, including The Wall Street Journal. Dow Jones also owns Barron’s, Investor’s Business Daily and MarketWatch, among other media properties.
Polymarket also has marketing deals with Major League Baseball (MLB), Major League Soccer (MLS), the NHL and UFC.
While the Polymarket/Yahoo Finance situation is one of the earliest examples of a severed relationship between a prediction market operator and a media entity, that doesn’t mean those “divorces” will permeate the two industries.
