Mario Bros. Wonder – How to unlock the final stage, Final-Final Test Badge Marathon
This guide will show you how to unlock the secret final stage
Super Mario Bros. Wonder’s secret last stage, The Final-Final Test Badge Marathon is one of the hardest levels in the game.
This five-star level – which only unlocks after you’ve seen everything wonder has to offer – requires players to complete a course using every major badge in the game.
Badges are new powers and modifiers which players unlock during the game, which can be equipped and swapped out before each level.
Read on to find out how to beat Mario Wonder’s final level, The Final-Final Test Badge Marathon.
How to unlock Final-Final Test Badge Marathon
The Final-Final Test Badge Marathon is unlocked once you’ve collected every Wonder Seed in worlds one through six, and the Petal Isles, and the Special World.
You also need to collect all Flower Coins (aka purple coins) and finish at the top of the flagpole in each level. You can track which levels you’ve done this on via the stage select screen, which should show a green tick in the background if you’ve fully completed it.
Once you’ve done all this, the secret last stage will appear.
How to beat Final-Final Test Badge Marathon
This five-star level requires players to complete a course using every major badge in the game and has minimal checkpoints.
We’ve embedded a video below of us finishing the level to give an idea of the route through the stage. We recommend purchasing 99 lives from a vendor before heading inside – you’re going to die a lot!
Once you’ve completed this course, a final house, ‘Wonder?’ will unlock and thank you for playing the game. Your reward is the Sound Off badge. Congratulations!
