How to play Mr. Do!'s Castle on Mac

Game summary

Mr. Do!, that king of arcade clowns, is in a bit of a bind - again! This time, a pack of pesky unicorns is trampling the bricked hallways of his castle. Help Mr. Do! rid his dwelling of these crafty, quick-changing (and deadly) creatures with the skillful swing of a hammer. Sometimes a quick clobber to the head will do it. Or maybe a well chosen brick knocked out from above. If you can't stop these critters, then break a hole in the floor to slow 'em down. It's up to you to know when to fight - or when to flee! Tension mounts as you hurry Mr. Do! through the castle's maze, grabbing keys along the way. Only when Mr. Do! has collected all the keys can he unlock the castle door, and open up an extra chance to beat these nasty critters!
First released: Dec 1983

Play Mr. Do!'s Castle on Mac with Parallels (virtualized)

The easiest way to play Mr. Do!'s Castle on a Mac is through Parallels, which allows you to virtualize a Windows machine on Macs. The setup is very easy and it works for Apple Silicon Macs as well as for older Intel-based Macs.

Parallels supports the latest version of DirectX and OpenGL, allowing you to play the latest PC games on any Mac. The latest version of DirectX is up to 20% faster.

Our favorite feature of Parallels Desktop is that when you turn off your virtual machine, all the unused disk space gets returned to your main OS, thus minimizing resource waste (which used to be a problem with virtualization).
