Nintendo World Report was critical of the game, praising its aesthetic but feeling that its puzzles were illogical and gameplay nonexistent. Famitsu felt that it was cute, though thought it may be difficult for small children to play. It found the music lacking, suggesting that it and other Game Boy Color music would only appeal to a limited audience. Jeux Video praised the visuals and the dialogue mechanics, calling it amusing. Eurogamer similarly praised efforts to make the game appealing to all ages while also commending Nintendo for making a game about a language barrier. IGN found it to be original and engrossing for all ages, praising its visuals and animations relative to other Game Boy Color games. GamePro and X-Play expected it to be a success among children, with GamePro calling its gameplay 'oddly compelling. Nintendo Power praised it for its 'clever and amusing' design. It is the seventh best-selling Game Boy Color game in Japan, with 497,061 copies sold. Hamtaro: Ham-Hams Unite! has received generally positive reception since its release. The game features mini-games, including Ham-Jam where players can dance to the game's music using different Hamchat words, and Tack-Q Bowling. Sunflower seeds are a currency that can be exchanged for clothing items which Hamtaro can wear, which players can trade with each other using the Game Boy Color's infra-red port. These words are unlocked by interacting with other characters.

Characters may require words that are not yet available, indicated by question marks included in the dialogue choices, in order to fully interact with them. There are other words that players learn throughout the game that can be used in contextual situations. Hamchat words are accompanied by gestures. Players have four Hamchat words as options by default: 'Hamha' for talking, 'Digdig' for digging, 'Tack-Q' for tackling, and 'Hif-Hif' for sniffing, all of which allow players to interact with characters and environments and may help progress the story. Players do this using the appropriate dialogue options to solve puzzles and appease other hamsters. Several of the characters from the anime, such as Bijou and Oxnard, are featured in the game as characters Hamtaro must seek out.

He is tasked to do this by Boss, who also teaches him basic Hamchat words. Players control protagonist Hamtaro as they seek out the various members of his clubhouse and attempts to fill in the Hamchat dictionary. Players can use dialogue options to have Hamtaro interact with characters and environments. The successor of the 2000 Game Boy Color game Tottoko Hamtaro: Tomodachi Daisakusen Dechu, it was followed by Hamtaro: Ham-Ham Heartbreak in 2003 for the Game Boy Advance which featured similar gameplay mechanics. It was the seventh best-selling game for the Game Boy Color in Japan. The game received generally positive reception, with reviewers such as IGN and Eurogamer noting its success as both a game for children and a game that could appeal to older audiences. Players control the hamster Hamtaro, who is tasked with gathering his friends and returning them to the clubhouse as well as collecting words missing from the Hamchat dictionary. It was the final video game published on the Game Boy Color by Nintendo. It launched in Japan in 2001, and later came to North America and Europe in 20 respectively. It is based on the Hamtaro anime and features much of the same characters.
