Board Game Arena

Please implement AI players so any game could be played anytime, even if the game is not popular.

no

All of us? For every game?

There's a recent thread about how feasible this is that you may want to read first. The short answer (but longer than "no") is that it's a tremendous amount of work that must be put into each game individually, not a blanket "just add AI" that can be done for everything at once.

Also, note that when you code a board game, you use the rule book as a base, to implement in the code what a player can and cannot do when it's their turn.

Most of the time, there is no such rule book for an AI.
What is the better play to do when it's the AI's turn ? Hard to tell.
