Rih rih khao sahn is the name of a traditional Thai children's game, in which two players hold their hands together and lift their arms forming an arched doorway, whilst other players walk through the arch in a row.

Whilst doing so, they are holding the waist of the person in front and singing a song which starts with the words rih rih khao sahn, hence the name of the game.

On the last words of the song, i.e. phaan ao khon khaang lang wai phiang tua, which translates as ‘catch the person in the back’, the two players forming the arch, bring their arms down, thus locking the gate and blocking anyone in the back. The person who is locked down within the arch is either eliminated (fig.) or punished by having to fulfill a certain behest.
