First you need to allow your system to install apps from “App Store and identified developers” (or possibly “Anyone”, depending on what else needs to be installed other than XQuartz and Wine).
Here we install the game on macOS Sierra / High Sierra (the screenshots are from Sierra). This post takes a closer look on one of this techniques, namely Wine (acronym for “Wine Is Not an Emulator”), that allows running native Windows software on POSIX-compliant operating systems, such as Linux, macOS, & BSD, without need for a Windows license. Recent developments in virtualization, emulation and techniques that allow running of applications developed for “foreign” platforms as if they were native ones, have made it relatively easy, and often free, to use the same app in mixed environments.
