Play Mini 4 Boy (Japan) Online
Pick a weird little Game Boy minigame—race with slippery cars, solve puzzles, or just figure out what’s happening. Feels like finding a forgotten demo cartridge in an old drawer.

Mini 4 Boy is a Japan-exclusive Game Boy title from 1990, developed by I'Max and published by Coconuts Japan. It arrived early in the handheld's life, a time when developers were still exploring what kinds of experiences worked on the small, monochrome screen. This game is a simple, almost experimental title that feels more like a collection of small activities than a single cohesive adventure.
You control a small car from a top-down perspective, navigating through a series of single-screen maze-like courses. The main objective is to drive from the starting point to the goal in each stage, avoiding walls and obstacles. The car handles with a deliberate, slippery momentum that makes precise navigation a constant challenge. Progression is screen by screen, with each new layout presenting a fresh puzzle of route planning and timing. It is a game of patience and gentle precision, and finishing a tricky course brings a quiet, satisfying sense of relief.
