Look, we’ve all been there. You’re deep into World Crown, the music is pumping, your palms are sweating, and suddenly that "Too Bad!" screen pops up for the tenth time in a row. You look at your life counter. It’s at two. Panic sets in. Losing all your progress in a tough Mario level is a rite of passage, sure, but in Super Mario 3D World (whether you're on the original Wii U version or the enhanced Nintendo Switch port), it's also entirely optional. You don't actually need to play fair.
Getting mario 3d world infinite lives isn't even a glitch, really. It’s more of a long-standing tradition. Nintendo developers have been tucking these "infinite" loops into games since the NES days, and 3D World has one of the easiest, most satisfying versions of the trick ever conceived. It’s basically a legal cheat code.
Why You Actually Need 1,110 Lives
Most people think "infinite" means the counter just stops at 99. Nope. Not in this game. If you do this right, your life counter will eventually turn into crowns. It’s a status symbol.
Honestly, the game gets brutal. While the early worlds are a cakewalk, the post-game content—specifically World Flower and World Crown—is designed to eat your lives like a hungry Yoshi. Champion’s Road, the final, final level, is notorious. Most players lose hundreds of lives just trying to clear that one single stage. If you go in there with 10 or 20 lives, you’re going to be staring at the Game Over screen more than the actual gameplay. That’s why the mario 3d world infinite lives trick is basically mandatory for anyone who isn't a platforming god.
The World 1-2 Infinite Shell Loop
This is the big one. It’s the method everyone uses because you can do it within the first ten minutes of starting a new save file. You don't need fancy power-ups. You don't need to be an expert. You just need a Koopa and a very specific corner.
First, load up World 1-2, "Koopa Troopa Cave." Head into the underground section. You’ll eventually come across a Koopa Troopa walking around near some purple bricks and a small alcove. This is your victim.
Jump on the Koopa to knock him out of his shell. Grab that shell. Now, find the tightest corner you can find—there's a perfect spot right after the first clear pipe where two walls form a neat little "U" shape or a tight corridor. If you stand against the wall, face the opposite wall, and throw the shell, it should bounce back and forth rapidly.
Here is where the magic happens. You need to jump on the shell and stay there.
Wait. Don't just jump and land. You have to time it so Mario (or Peach, or Luigi) keeps bouncing off the shell without touching the floor. Because the shell is trapped in a tiny space, it vibrates back and forth at high speed. Every time you "hit" it, the game registers a jump. After about eight bounces, the sound effect starts pitch-shifting higher. Then come the 1-UPs.
It’s loud. It’s chaotic. It’s beautiful.
If you position yourself just right, you can actually put the controller down. Mario will keep bouncing automatically. You can go make a sandwich, watch a YouTube video, or stare blankly at the wall for ten minutes. When you come back, your life counter will be maxed out.
The "Crown" Secret
If you’re wondering why some people have icons of crowns instead of numbers in their life count, it’s because they hit the absolute cap.
The game tracks lives up to 1,110. The digits represent "Crown, Crown, Crown." Achieving this isn't just about safety; it's about completionism. Also, a little-known detail: if you manage to keep those 1,110 lives (the Triple Crown) all the way to the end of a level, Mario will lose his hat. It’s a tiny, weird cosmetic "reward" that Nintendo threw in for the players who went the extra mile to break the life counter.
Does it work in Bowser’s Fury?
Since the Nintendo Switch version comes bundled with Bowser's Fury, players often ask if the mario 3d world infinite lives trick works there too.
The short answer? No.
Bowser's Fury uses a completely different life system. Instead of a counter, you collect coins to earn power-ups. When you "die," you just lose some coins and respawn nearby. It’s much more forgiving, which is probably why Nintendo didn't feel the need to include a shell-bouncing exploit in that mode. It's a different beast entirely.

Other Ways to Farm Lives (The "Slow" Methods)
If the shell trick feels too much like cheating for your tastes, there are other ways to stock up. They’re just... slower.
- Slot Machines: Every time you see a Toad House with a slot machine, use it. If you’re good at timing (or just lucky), you can pull in a decent haul of 1-UPs.
- The Goal Pole: If you hit the very top of the Goal Pole, you get a 1-UP. It sounds small, but if you do it every single level, it adds up.
- 100 Coins: Standard Mario rules apply. Grab 100 coins, get a life. In 3D World, coins are everywhere. Don't ignore them.
But let’s be real. If you’re at World 9 and struggling, you aren't going to farm coins. You’re going back to World 1-2.
Common Mistakes to Avoid
I’ve seen people mess up the shell trick a lot. The most common error is picking a spot that’s too wide. If the shell has too much room to move, you’ll eventually slip off or the shell will fly away. You need a space that is literally just wide enough for the shell to rattle.
Another mistake: using Peach. While her floaty jump is usually a godsend, it can actually make the initial "lock-on" to the shell a bit harder because she stays in the air too long. Mario or Luigi are generally better for setting up the loop quickly. Once the loop is started, it doesn't matter who you're using.
Actionable Steps for Your Next Session
If you want to secure your save file and never see a Game Over screen again, follow these steps exactly:
- Enter World 1-2 as Mario or Luigi.
- Navigate to the underground area and find the first Koopa Troopa.
- Dispose of the enemies nearby so you aren't interrupted.
- Find the three-sided brick alcove near the clear pipe.
- Face the wall, throw the shell, and immediately jump.
- Adjust your horizontal position until you see the score numbers turn into "1-UP" text.
- Leave the game running for about 15 minutes to hit the 1,110 life cap.
This basically removes the stress of "Game Over" and lets you focus on the actual challenge of the level design. It’s especially helpful if you’re playing co-op with kids or friends who might not be as experienced, as they tend to burn through the shared life pool pretty quickly. Get those crowns and get back to the game.
