Hamtaro is a cute hamster with lots of hamster friends. Originally a Japanese children's book, Hamtaro was introduced to movies and television around the world, and, of course, made into video games and toys. GameZone never watched Hamtaro much (due to my being too cheap to pay for a cable lineup featuring the Cartoon Network), but we enjoyed the GBA games, especially Ham-Ham Heartbreak.
Unlike previous Hamtaro games on handheld systems, Hi! Hamtaro Ham-Ham Challenge is designed primarily for very young players. It is essentially a collection of light "edutainment" games, which focus on critical thinking skills, creativity, recall and counting. There are 12 activities in all.
