Movements, situations, and emotions are also OK! Words are infinite depending on your ideas!.

Players drop a black ring onto the illustration sheet, find the first word for Shiritori from within the ring, and then start. Everyone searches the illustration sheet for words that connect to the next Shiritori word. In addition to names of objects, words like "walk," "lively," "thank you," and "munching" are also fine. The person who finds a word quickly says it and places their ring on that illustration. The first person to place all six of their rings by continuing the Shiritori chain wins.

Fun to play together around a large illustration!

The B3-sized illustration sheets come with 4 types (front and back), so you can play in various scenarios. With simple rules, it's a new sensation Shiritori game that can be enjoyed by all generations, from children to adults, on a first-come, first-served basis.
