Sanrio Carnival is a puzzle game that challenges players to match block objects of the same type in rows of three, four or five. The game features Hello Kitty and her friends, adding a fun and colourful twist to the classic genre.
The gameplay is similar to Dr. Mario , with players trying to eliminate all the viruses by matching coloured blocks. However, instead of traditional medicine, the player must match block objects of the same type in a horizontal or vertical row. The game offers three different single-player styles, each with its own unique goals and options to choose from.
