One of my favorite computer programs is solitaire, the usual game. I play several games each day and have noticed several anomalies in how the game goes on the computer. In other words, the computer makes mistakes.
Here is a goof in the rightmost column. Notice that a red 5 of hearts at the bottom is on top of a red 4 of hearts. That is contrary to the rules. I have encountered many such errors in playing the game.
Here is my high score so far. My goal is to make 10,000 in 80 seconds or less.
