Play Trump Boy (Japan) Online

Trump Boy is a Japan-exclusive Game Boy title released in 1990, developed by TOSE and published by Nintendo. It arrived during a period when the handheld was still building its library, offering a digital take on a traditional card game rather than an action or adventure experience. The game is a portable adaptation of President, a climbing/shedding card game popular in Japan, and it presents a straightforward, no-frills approach to the genre.

You play against up to three computer opponents, with the goal of being the first to get rid of all your cards each round. The core mechanics involve playing single cards or sets of equal cards to beat what's on the table, with higher ranks or longer sequences required to take control. Special cards like jokers and the 2 can reset the play pile or act as powerful wildcards. The pacing is quick, and the AI provides a decent challenge, often holding back strong cards to trap you later. It feels satisfying to correctly predict an opponent's hand and force them into a corner with a well-timed play.
