The "Rule of the Twins" is simple and applies to the basic structure of a keno way ticket.
We observed years ago that in fact on every keno ticket if you take away a certain number of spots, that leaves a certain number. Indeed when t = the total number of spots on the ticket (we will limit this to 15 for simplicity) and you take away x spots that leaves y spots. If t = x + y then there will be the same number of x ways as there are y ways.
If this is clear as mud to you I will give you a concrete example because I am compassionate. Ha. Really let’s take a 9 spot ticket and group it 3-3-1-1-1. From the previous few lessons (I know you were paying attention) we know this ticket has five groups and thus 31 total ways on it.
Now since there are 9 spots on the ticket, and 6+3 = 9 then the Rule of the Twins states that there will be the same number of six spot ways as three spots. Now you can see from inspection that there are three ways to make three (3x 2 and 1-1-1) thus we can be confident that there is also a three way 6. Indeed there are three sixes (3-3 and 3-1-1-1 x 2.)
Of course that is a very simple ticket but the Rule of the Twins really speeded up the calculations involved in more complex tickets. Take the 15 spot grouped 3-3-2-2-2-1-1-1. Suppose the player wants to play the 10s on the ticket. This can be worked out but the process is somewhat laborious.
However if you note that on a 15 spot ticket, the number of 10s equals the number of 5s, and 5s are much easier to discern, then you can quickly calculate the number of 5s and be confident that it is also the number of 10s. Well you can make a five by 32 (6 ways) by 3-1-1 (6 ways) by 2-2-1 (9 ways) and by 2-1-1-1 (3 ways) so there are a total of 24 fives and thus 24 tens.
The ticket could be booked as verified and then only checked if needed.
If you get good at using the Rule of the Twins (it just takes a little practice) it will really increase your enjoyment of the game of Keno especially if you are a way ticket player.
