This is not a gamble. Wikipedia notes that it is suitable for all ages. I even think it is most often played by children.
Once upon a time, when I was a child, my cousin Larissa and I spent a lot of time playing this game during summer vacations in the countryside. Those were good times, when there were no computers yet. A lot has changed since then, and I decided to write this program in memory of those times.
I do not like the English-language name of this card game "War", so I left its original name, by which we knew it, but only in transliteration. This word means "Drunkard". Whoever loses all his cards is a drunkard.
In the game you can turn on the "auto play" and just watch - who will win. Or you can press the button yourself for each move. In the next version, Ill think about the possibility of removing the limit on the "auto play" by the number of moves. Also now you can choose to play a deck of 16, 36 or 52 cards.
