Play Pocket Color Trump (Japan) Online

Pocket Color Trump was a Japan only Game Boy Color release from 1999, developed by Bottom Up. It arrived during a period when the handheld was flooded with card and board game adaptations, offering a straightforward digital version of a classic pastime without much fanfare.

You play by matching wits against the computer in a series of trick taking card games, primarily Oicho Kabu. The main objective is to win rounds by playing higher value cards than your opponent, managing your hand carefully across multiple matches. Signature mechanics include bidding on the number of tricks you believe you can take each round and a simple but effective card selection system that requires you to anticipate the AI's moves. The pacing is methodical, and the difficulty can spike unexpectedly when the opponent seems to hold all the right cards at the right time. It feels like a quiet, sometimes frustrating battle of wits that is perfect for short sessions.
