Nintendo showed off three new Super Mario Odyssey levels over the weekend at its annual World Championships event.

The NWC 2017 finale saw title rivals John Numbers and Thomas G take on the trio of levels for the first time.

Apart from one brief glimpse during a Nintendo Direct earlier this year, these three levels have never been seen before - let alone made available for the two champion wannabes to practice.

And so both fans were thrown in blind: Thomas G prevailed on the first level, which mixes 2D and 3D Mario gameplay and timing needed to hit switches to line up platforms, but John Numbers mounted a valiant comeback on the second level, where Mario has to fling himself up a vertical wall using the powers of new headwear sidekick Cappy.

All of which left John Numbers and Thomas G level for the final Mario Odyssey level - a boss fight against a statue head with floating hands. By capturing a hand, you can then direct it back towards the boss' head and punch it in the face.

You can watch the three levels below:
