Ninjago: Masters of Spinjitzu Season 12

While investigating a heist, the ninjas discover a legendary unreleased arcade game that suddenly takes control of all the other games in Ninjago.

When the ninjas connect Jay's disappearance to Prime Empire, they head to Dyer Island to seek answers from the game's designer, the elusive Milton Dyer.

Cyrus Borg discovers a shocking secret about Prime Empire, while the ninja battle an escaped Mechanic in their attempt to reach Level Thirteen.

Now inside the Prime Empire game, the ninjas find themselves in unfamiliar territory as they try to find Jay and evade an army of Red Visors.

Inside one of the game zones, a samurai named Okino faces a crisis of faith when he repeatedly fails to lead a series of masters to victory.

In order to stop Unagami, the ninjas must obtain three Key-tanas, the first of which is hidden in one of Prime Empire's most dangerous game environments.

While trying to cheer Okino up, the ninjas arrive at the Cliffs of Hysteria and must figure out how to climb them.

Still in the game zone Terra Karana, the samurai guide Okino has to chose between helping the ninjas or obeying the orders of his master, Unagami.

The ninjas learn that the only way to acquire the second Key-tana is by winning a race in Terra Technica — and must find racing cars in unexpected ways.

As the ninjas prepare for the brutal Speedway Five-Billion race, Lloyd meets a race driver named Seven — who may hold the key to victory.

Unagami's soldiers, the Red Visors, finally discover the secret location of Scott's garage — where they stage an attack against the ninjas.

The ninjas barely have time to mourn the loss of their fallen friends before being thrust into the chaos of Terra Domina.

Back in Ninjago City, Zane and Pixal hit the mean streets to track down Milton Dyer, only to discover that things are not what they seem.

Zane, kidnapped by the Mechanic, faces Unagami while Pixal questions Milton Dyer for information on how to shut down Prime Empire.

Jay must stand alone against Unagami in the end-game. But Unagami has a bigger battle in facing the truth about his own identity.

When Unagami breaks into the real world and terrorizes Ninjago, Jay, Zane and Pixal attempt to prevent disaster by reuniting him with his creator.
