The 9 advanced cards require players to perform calculations based on variables determined by rolling the dice and subsequently giving the result using digits from one of the Babylonian, Egyptian, Mayan, Arabic, Roman, Chinese and binary numeral systems. This is achievable thanks to the 165 special tiles provided (some tiles are shown here by way of example).
Learning about and actively practicing different numeral systems (base numbers 2, 10, 20, 60; addition methods, positional notation and mixed methods) is highly instructive and can be compared in this sense to learning one or more foreign languages.
The structure of the numeral systems featured is explained in the first section of the game book. Le risposte alle domande riguardo a sistemi di numerazione diversi si danno componendo il risultato con le tesserine (a fianco, qualche tesserina come esempio).
In addition, squares 4, 6, 11, 19, 29 and 34 have a key containing digits from the various numeral systems so that players always have them to hand (as illustrated in the adjacent examples featuring squares with Egyptian and Mayan numbers).
