How do the 220 pannas break down?
Single patti (three different digits): 120. Double patti (two alike): 90. Triple patti (three alike): 10.
Why is it written 120 and not 012?
Digits go in rising order, but 0 counts as the highest digit, as if it were 10.
What is the 22 patti chart?
Divide 220 by ten anks and each ank gets exactly 22 pannas. That per-ank list is what players call 22 patti.
