ELI5: Explain Like I'm 5

Nintendo e-Reader

Okay, so imagine you have a deck of cards that can talk to your Nintendo Game Boy. That's kind of what the Nintendo e-Reader is!

The e-Reader is a small device that you can plug into your Game Boy. It has a little screen on it, and a slot to slide cards through. Each card is called an "e-Reader card" and it has a special pattern on it that tells your Game Boy what to do.

When you slide an e-Reader card through the device, it sends a message to your Game Boy and something new happens in your game. Sometimes it adds new levels or items, or even changes the way your game looks.

The e-Reader cards can also be used to play mini-games on their own. Each card has its own unique game that you can collect and play with your friends.

So basically, the Nintendo e-Reader is a fun accessory that lets you add new things to your Game Boy games and play mini-games with special cards. It's like a talking deck of cards that can make your games even more awesome!
