How to Unlock Characters in Dr. Mario World

The kicker here is how to go about unlocking Doctors or Assistants. There are a few general requirements to meet, but otherwise, it’s completely random. Here are the steps: 

  1. First, you need to level up to Level 20 and clear the first World.
  2. After that, you can spend 4,000 Coins or 40 Diamonds to unlock a Doctor or Assistant.

If you need a refresher about how Coins and Diamonds work, head over here to check out our overview.

You have no control over which Doctor or Assistant you unlock. Each doctor has a 2% drop rate, while all the Assistants have a 2.67% drop rate.

It’s possible to end up receiving duplicates of the same Doctor or Assistant as well. Should that happen, it levels up your character, but the duplicates won’t be removed from the pool of potential unlockables until you’ve maxed out that character’s skill level.

Diamonds in Dr. Mario World

Should you wish to purchase characters with Diamonds, know that you can’t buy Diamonds individually. Instead, they come bundled.

  • 20 Diamonds — $1.99
  • 53 Diamonds — $4.99
  • 110 Diamonds — $9.99
  • 250 Diamonds — $19.99
  • 550 Diamonds — $39.99
  • 1050 Diamonds — $69.99

If you don’t feel like doing the quick math, just know that should you want to use Diamonds for all the characters, you’ll need more than 1,200 for the Assistants alone, and that’s not taking into account duplicates.

Unless you want to spend money for the heck of it, Coins or a mix of Coins and Diamonds are likely your best bet here.
