Game setup

Difficulty (starting level)

What is Hagure Hunt?

Hagure Hunt is an observation game where you spot and tap the single odd-one-out emoji in a grid packed with near-identical emoji, all against a time limit. Hunting for one target among many is what psychologists call "visual search," and Hagure Hunt trains exactly that ability — noticing a small difference in a mass of information and moving your attention quickly from spot to spot. The higher your level climbs, the larger the board grows, from 3x3 up to 6x6, while the emoji also grow more similar to each other (similarity tiers 1–4). Early on the color or shape differs enough to catch at a glance, but at higher tiers it comes down to a slight difference in orientation or expression, demanding the patient focus to compare cell by cell. A wrong tap costs you 2 seconds, so calmly confirming before you press beats mashing at random. The trick to finding it fast is not to stare at the whole board, but to fix a scan path — top row to bottom, left to right — so nothing is skipped; once you're used to it, switching your focus from color to shape to orientation makes differences pop out. Because it's endless mode, you can push to see how far you get, and only your highest level reached is kept as a record on your device. Each round is short, making it a brain-training break that fits neatly between study or work.

How to play

When you start, a grid of nearly identical emoji appears.
Look for the one emoji that is subtly different from the rest.
Once you find it, tap that emoji before time runs out.
A correct tap levels you up and moves you to the next board.
As your level rises, the board gets bigger and the emoji look even more alike, raising the difficulty.
Tapping the wrong emoji costs you a 2-second penalty off your remaining time.
Each time you clear a level, confetti celebrates your achievement.
Keep going until time runs out and aim for the highest level you can. Your best level is recorded.
