Utchan Nanchan no Hono no Challenger: Denryuu Ira Ira Bou

Utchan Nanchan no Hono no Challenger: Denryuu Ira Ira Bou is a puzzle game for the Nintendo 64 released only in Japan in 1997. It is based on a segment of the Japanese game show Utchan Nanchan no Hono no Challenger: Kore ga Dekitara 100 Man En!!

The game follows the same playing principle as the mechanical wire loop game. In this variant, the player has to guide a ball through six courses which basically consist of narrow ways with curves and obstacles. The player is not allowed to touch anything and has to solve the course within a time limit.
