Valvo is a board game (although its authors also define it as a strategy game) that has many points in common with the popular Backgammon.
In Valvo two players face each other. You must perform each of your movements with a lot of strategy and using tactical actions, as well as demonstrating your intelligence skills before carrying out any movement (both to win and to prevent your opponent from winning before you do).
You have, in Valvo, up to 6 levels of difficulty, and some of them have considerable complexity. In addition, Valvo is totally free.
You can free download Valvo 32, 64 bit and safe install the latest trial or new full version for Windows 10 from the official site.
