JILI Fishing Games: How the Genre Works

A genre that barely exists in Western catalogues and is enormous across Asia. Here is what fishing games are and how the maths underneath them works.

If you have only encountered slots and table games, fishing games look bewildering: an underwater scene, shoals of animated fish drifting across the screen, and a cannon at the bottom that you aim and fire. It is one of the largest game categories in Asia and almost unknown elsewhere.

The basic loop

You control a cannon. Each shot costs a set amount. Fish swim across the screen, each with a displayed multiplier value — a small fish might be worth 2x your shot cost, a large boss creature 200x or more. Hit a fish enough times and it dies, paying out its multiplier.

“Enough times” is the crucial part. A fish is not killed by a single hit; each hit has a probability of killing it, weighted so that higher-value fish take proportionally more shots. You are spending ammunition continuously and collecting payouts intermittently.

The maths underneath

This is where fishing games differ from slots in structure but not in outcome. A slot resolves each spin independently. A fishing game resolves continuously — your cost accrues per shot, your return accrues per kill — but the long-run RTP works exactly the same way.

The kill probability for each fish type is set so that, across enough shots, the game returns its designed percentage. A 50x fish is not fifty times harder to kill than a 1x fish by coincidence; the ratio is engineered.

What skill actually contributes

There is a genuine skill component, and it is narrower than it appears.

  • Aim. Shots that miss entirely are pure loss. Leading a moving target correctly is a real skill and the main thing separating competent players from poor ones.
  • Target selection. Firing at a boss fish you cannot finish before it leaves the screen wastes everything you spent on it.
  • Cannon power management. Most games let you adjust shot power. Higher power costs more per shot and improves kill chance. Matching power to target value is a real decision.

What skill does not do is overcome the house edge. Good play reduces waste and brings you closer to the designed RTP. It does not exceed it.

Typical features

  • Special weapons — lasers, nets or bombs that hit multiple targets, usually at a higher cost per use.
  • Boss events — a large creature appears for a limited window with a high multiplier, and everyone at the table fires at it.
  • Multiplayer rooms — several players share a screen. You compete for the same fish, and this is a genuine strategic layer: letting someone else soften a boss and taking the kill is a known tactic.
  • Room tiers — separate rooms with different shot costs, from very low stakes to high.

JILI’s version

JILI handles the genre about as well as anyone and it is the studio’s strongest category. Hit detection is responsive, the art is readable at speed — which matters when a dozen things are moving — and performance holds up on modest phones. The titles are differentiated enough to be worth trying several.

The honest caveat

Fishing games feel skill-based in a way slots do not, and that feeling is the design working. The active aiming, the visible progress on a boss, the sense of a near miss — all of it creates an impression of control over an outcome that remains negative expected value. Enjoy the genre for what it is, and do not mistake engagement for edge.
