Hvis man tilfældigvis har et barn i 5-årsalderen, kan man spille kortspillet Krig. Kortene blandes og deles ligeligt mellem 2 spillere, hver spiller vender et kort fra sin bunke samtidig, højeste kort vender, hvis kortene er lige høje, er der krig. Det er så enkelt, at man lige så godt kunne få en computer til at spille det.
Derfor skrev jeg et lille program i Python, der kan simulere kortspillet.
Jeg opdagede et hul i reglerne: Der er ingen steder, der beskriver, hvad der sker, når en spiller ikke har kort nok til at deltage i en krig (eller en dobbelt-krig, tredobbelt-krig, osv.) Jeg besluttede, at hvis en spiller på et tidspunkt mangler kort til at kunne deltage, taber den spiller, der ikke har kort nok til at deltage. I den meget sjældne situation, at begge spillere ikke har nok kort til at deltage (en mange-mange-dobbelt-krig i starten af spillet), vinder den spiller, der har flest kort. Har begge spillere lige mange kort, bliver det uafgjort.
Jeg fik computeren til at spille 1 million spil Krig, og her er hvad jeg kan fortælle dig om Krig, som du ikke vil vide:
- Det gennemsnitlige antal dueller i et spil krig er 177
- Spillet med flest dueller havde 1.825 dueller
- Spillet med færrest havde 4 dueller
- Spilleren med den højeste sum af kort efter kortene blev blandet vandt 573.405 gange
- Spilleren med den laveste sum af kort vandt 397.602 gange
- I løbet af spillene blev der spillet:
- Enkeltkrig: 12.366.762 gange
- Dobbeltkrig: 888.024 gange
- Trippelkrig: 60.727 gange
- Firdobbeltkrig: 3.852 gange
- Femdobbeltkrig: 206 gange
- Seksdobbeltkrig: 10 gange
