Ordeal of Balls (玉の試練 Tama no Shiren?) is managed by the priest Satori of the wandering forest. The survival rate of this trial is 10%. In the English version of Pirates Carnival and FUNimation's edited-for-TV dub, it's called the I.Q. Orb Test, but in the FUNimation's uncut DVDs, it's called the Ordeal of Spheres. It first appeared in Chapter 246 and Episode 160.
