Nintendo has released its latest mobile game, and this one brings Dr. Mario to your smartphone. Dr. Mario World is available on Android and iOS, and it will be familiar to anyone who has played the various iterations released over the years. Albeit with a twist.

Dr. Mario first graced consoles when it was released on the NES and Game Boy in 1990. It has since been re-released, ported, and remade for various other consoles, including the 3DS and Wii U. And now Dr. Mario has arrived on mobile in the form of Dr. Mario World.

What Is Dr. Mario World?

Dr, Mario World casts you in the role of a doctor trying to kill viruses. You do this by placing colored pills in the right place. Just think Tetris but with pills rather than blocks. However, unlike Tetris, you can take your time in placing your pills.

As with most mobile games these days, Dr. Mario World is free-to-play. However, the in-app purchases mean there's plenty of opportunity to spend money. You won't necessarily need to spend any money, but the game is designed to tempt you into doing so.

You can spend your money on diamonds. These can then be used to buy coins, hearts, and other power-ups. Hearts are what you need to keep playing, and beating a level earns you a heart. But if you run out of hearts they take half an hour to replenish.

This system will be familiar to anyone who has played Candy Crush Saga. And it boils down to the game making you choose between spending a few dollars to keep playing or being patient enough to wait. Thankfully, the online multiplayer is always available.

Dr. Mario World should appeal to anyone who loves Nintendo or puzzle games. Both the single-player and multiplayer elements are fun, but anyone playing alone will have to resist the urge to spend real money on diamonds. But that's modern mobile gaming for you.

After years of resisting the urge, it looks like Nintendo is fully embracing mobile gaming. For better or worse. Still, Dr. Mario World is a great puzzle game, and here are some other cool puzzle games you can play for free in your browser.
