"According to Microsoft telemetry, Solitaire was among the three most-used Windows programs and FreeCell was seventh, ahead of Word and Microsoft Excel."
Damn! Throwback
At university I made some money on the side giving courses in HTML, Excel etc. One person that was mandated by an employer to follow such a course had extreme trouble using the mouse. I opened Solitaire and showed quickly how to click and drag. The person in question had to confess he also did not know how to play Solitaire.
