How many moons are in Mario Odyssey, and what do you get?
Super Mario Odyssey has 880 Power Moons to collect (Multi Moons count as three), and buying the 119 shop moons brings the counter to its maximum of 999. Collecting them all doesn't unlock a new ending or a secret final boss; at 999 a top hat appears on Peach's Castle, and that is essentially the reward — bragging rights for finishing one of Nintendo's biggest collect-a-thons. The meaningful unlocks happen earlier: the Dark Side of the Moon at 250 moons and the Darker Side at 500.
How the moon count works
- 880 unique Power Moons are hidden across the kingdoms. These are the moons you actually find, earn or buy one by one.
- Multi Moons (usually dropped by bosses) count as three moons each, which is why the counter climbs faster than the number of unique moons you've collected.
- The counter stops at 999. All 880 collectible moons (with Multi Moons counted as three) plus the 119 moons you can buy with coins from Crazy Cap shops after the story make exactly 999.
Milestones that actually unlock something
- Finish the story — once Bowser is beaten, Peach and Luigi's Balloon World appear across the kingdoms and many new moons open up.
- 250 moons — the Dark Side of the Moon (Rabbit Ridge) becomes available, with a set of tough challenge courses.
- 500 moons — the Darker Side of the Moon opens. Its single long platforming gauntlet, Culmina Crater, is widely considered the hardest moon in the game.
- 999 moons — the counter is full and a top hat appears on Peach's Castle. There's no extra ending; it's a completion milestone.
Is it worth going for every moon?
If you enjoy the movement and exploration, yes — the late-game challenges are some of the best platforming in the series. If you only want the story, 124 moons get you to the credits. Expect roughly 60 hours or more to clean up everything, depending on how much you use guides.
FAQ
How many Power Moons do you need to beat Mario Odyssey?
The story minimum is 124 moons; you can collect more on the way, but 124 is enough to finish the game.
Is there a reward for getting all moons in Mario Odyssey?
Not a big one. The main reward is the full 999 counter and a top hat on Peach's Castle; the real unlocks are the Dark Side at 250 moons and the Darker Side at 500.
What happens at 500 moons in Mario Odyssey?
You unlock the Darker Side of the Moon, a final post-game kingdom with one long, difficult course that tests every move in Mario's toolkit.
How many endings does Mario Odyssey have?
One. After the credits you keep playing in the same save, but the story ending doesn't change no matter how many moons you collect.
Can you 100% Super Mario Odyssey?
Yes. Collecting all unique moons, purple regional coins and costumes is achievable in a single save; nothing is permanently missable.
