Crayon Shin-chan: Puzzle Daimaou no Nazo

This game portrays Shin-chan's lifestyle and antics in the form of a mini-game match against his parents, classmates and others. The rules are very much like that of a classic falling block puzzle but with some differences. Two matching blocks will merge together into larger blocks and blocks of the same kind (small and large) in specific sized arrangements or a row of four will make them vanish. Two wildcard blocks will cause various things to happen such as spamming the opponent with rock blocks.
