Play Jantaku Boy (Japan) Online
You frantically slap down weird-faced tiles while a snarky AI throws off your rhythm—it’s Tetris’ janky cousin with unsettling charm and that classic Game Boy earworm soundtrack.

Jantaku Boy is a Japan-exclusive puzzle game released for the Game Boy in 1990, developed by I'Max and published by Irem. It arrived during the handheld's early years, a time when developers experimented with the system's limitations, often producing niche titles that never left Japan. This one fits right into that experimental, slightly odd corner of the Game Boy library.
You control a cursor on a grid, placing tiles that display various facial expressions to match rows or columns before a timer runs out. The main objective is to clear the board by forming complete lines, but a computerized opponent frequently drops new tiles to disrupt your progress. The game requires quick pattern recognition and forces you to adapt your strategy under pressure, as the AI's interruptions make the pace feel frantic and unpredictable. It feels like a tense, slightly chaotic race against a mischievous clock.
