Realizing that they've become part of a real-life version of the Capsule Monsters board game, the gang struggles to find a way out.

Reunited at last, Yugi and his friends rejoice. But their celebration is soon interrupted by a pack of man-eating wolves, a giant turtle and an angry Genie!

Grandpa translates an ancient stone tablet which directs the gang to locate the "Fortress of Fear." Now they have until sunset to find this mysterious structure or they'll be trapped in the world of Capsule Monsters forever!

Yugi and his friends discover that in order to return home to the real world they must pass a series of tests known as the Five Sacred Trials - the first of which pits them against enormous sand worms and a mysterious voice that travels with the desert wind.

After narrowly escaping their battle in the desert, the gang finds themselves stranded on a mysterious floating island. Here they must face a monster that derives its strength from the sun itself! But is this creature of light working alone!?

It's on to level three as Yugi and his friends are transported to a lava-covered wasteland. To make matters worse, Joey is possessed by an evil force, and destroying it may mean destroying Joey as well!

Yugi and his friends are faced with an impossible task – locating a magical apple in a forest full of apple trees. As if that wasn't difficult enough, they find themselves trapped in an endless maze with dangerous creatures around every turn!

The gang stumbles upon a small kingdom dominated by a clan of fierce dragons known as The Fiendish Five. If they fail to slay these beasts, one of Yugi's friends must give up his soul!

Yugi and his friends defeat the Fiendish Five…or so they think! These ferocious dragons have merged together and are now more powerful than ever! Will the gang complete their fifth and final test, or will they be trapped forever in the world of Capsule Monsters!?

Although the gang has passed the five sacred trials, the most dangerous test is yet to come. Now Yugi must face the spirit of Alexander the Great in an all-out Capsule Monsters war with the ultimate stakes!

Yugi's friends are unconscious, leaving him to defeat Alexander the Great on his own! However with the indestructible Reshef the Dark Being in his corner, Alexander seems undefeatable!
