Animal Crossing: New Horizons' Bells glitch is more accurately described as an infinite duplication glitch, but the final outcome is the same. Using this glitch, players can accrue as much in-game wealth as they desire. Here's how to perform the glitch and make your own ill-gotten fortune.
Animal Crossing: New Horizons Bells Glitch: How to Get Infinite Bells
The easiest way to perform this glitch is to invite another player over to your island. Once they've arrived, place the item you wish to duplicate on top of a piece of furniture that can hold other items. Have the second player rotate the piece of furniture just as you pick it up.
If you've performed the glitch correctly, you should have one copy of the item in your pockets and a second on the piece of furniture.
This glitch can be repeated endlessly for infinite wealth.
The glitch can also be performed solo using separate Joy-Cons to control the two characters.
