Jodi Family Chart
One row per jodi listing the rest of its family: the jodis built from the same two digits, and those built from their cut anks. Easy to print.
A family holds every jodi you can reach by reversing the digits or by swapping either digit for its cut ank (add five, drop the ten).
What a jodi family is
Start from any pair, say 16. Reverse it and you have 61. Swap one digit for the figure five away from it, its cut, and you reach 66, 11, 61 again and 16 again. Collect everything reachable that way and you have the family: the pairs built from the same two digits or their cuts. The site groups all hundred jodis this way, with the lowest pair of each group as its label.
Players use the families when reading a jodi or panel chart to spot which group a recent pair came from. It is a way of sorting past results; a family that has appeared often is not due, and one that has been quiet is not overdue, because every draw is independent of the last.
