Next:

• Decouple core game code from Qt
• Tests
• Harden impossible mode: can be beaten still in 1 specific way :^)

Nice to have:

• Continuous integration
• Backport build to Windows^†

Notes

^† The project was bootstrapped with and for Visual Studio 2008, and the story on MS build compatibility is unknown to me. So the build got moved to CMake which is commonly used with Qt projects.

The impossible mode AI can be beaten with the following moves:

_|_|4
_|_|1
_|2|3


To prevent this from happening, the computer must block at #3, when the user 
makes #2. This is done properly in the C# implementation, but is lost in 
translation.

2020 refresh

• Qt 4 -> Qt 5
• Linux-first build
• Visual Studio^† -> CMake
• Code organization / cleanup (pass 1)
• Fix impossible mode bug #2 (~10 year anniversary edition)
• Decouple computer move logic from window code

It can beaten like this


2|4|3
_|_|1
_|_|_

The proper response for the AI is to play in spot 3 when spot 2 is taken.
