Example: sakura -> rajio -> onigiri -> risu -> sumou -> udon
The word "udon" loses the game, as it ends with a syllabic "n". (Japanese words may not begin with a syllabic "n".)
Usually, only nouns are permitted.
In some variants, dakuten and handakuten (see Hiragana) are ignored. Thus "furo" can follow "suupu".
