Dr. Stone Wiki

Deal Game, Test of Wit (頭脳戦のディールゲーム Zunō-sen no Dīru Gēmu) is the forty-ninth episode of the Dr. Stone anime, and the fourteenth episode of the third season.


Ginro reveals that the head of the island is a stone statue and receives a fatal wound at the hands of Ibara. Due to Kohaku's quick decision, the two of them turn themselves into stone and wait for Senku and his friends to help them. Meanwhile, Senku revives his friends one after another and obtains a drone, his trump card for counterattack. They hear information from Amaryllis, who escaped from the chaos, and find out what's inside the enemy. Meanwhile, Moz, the strongest warrior of the Petrifying Kingdom, suddenly appears in front of Senku and his friends!!

Plot Details[]

Senku begins reviving the rest of the crew just as Amaryllis arrives with news of Kohaku and Ginro's petrification and that Soyuz is likely the Master's son. Senku and the others deduce there is only one Medusa weapon but due to the range of its attack, it risks petrifying the one who activates it, hence why Ibara dare not use it himself and forces Kirisame to instead. This also means Kirisame isn't aware the Master is petrified or how evil Ibara really is. Moz appears in the cave at that moment but in a moment of extremely rapid deduction, everyone realizes Moz knew Kohaku and Ginro were intruders yet never told Ibara, meaning Moz is secretly Ibara's enemy. Using every mentalist trick he knows, Gen has Moz admit he wants to kill Ibara and rule himself but only fear of petrification has stopped him. Moz agrees to help defeat Ibara but only if he can keep Medusa and become the new Master. They outfit Moz with his own sound-transmitting earring as he returns to the citadel. Needing Ibara worried enough to use the Medusa again, Senku sends Moz a modern scientific spear so he can attack his own men disguised as a Kingdom of Science warrior.
