Abstract [en]

Yatzy is the Scandinavian version of Yahtzee, a popular dice game known worldwide. This report compares the effectiveness between two strategies used when playing Yatzy in real life, an optimal strategy and a bonus-focused strategy. To evaluate this problem and determine which performs better or if they are somewhat equivalent, a Java program was constructed with the purpose of simulating 100 000 rounds of Yatzy following a bonus-focused strategy and the expected values was compared.

As the results will show, this study proves that a bonus-focused strategy should be preferred over an optimal one (now debunked, as proven in section 5) since the average score is greater, 215,70 compared to 189,80.

Abstract [sv]

Yatzy är den Skandinaviska versionen av Yahtzee, ett populärt tärningsspel känt världen runt. Denna rapport jämför effektiviteten mellan två strategier som kan användas när man spelar Yatzy i verkligheten, en optimal strategi och en bonusfokuserad strategi. För att bedöma vilken av strategierna presterar bättre eller om de är någorlunda likvärdiga, konstruerades ett javaprogram med syftet att simulera 100 000 omgångar Yatzy som följer en bonusfokuserad strategi och deras väntevärde jämfördes.

Denna studie bevisar att en bonusfokuserad strategi är att föredra över en optimal strategi (tidigare optimal, bevisat i kapitel 5) då medelvärdet är högre, 215,70 jämfört med 189,80.
