Pick the 3rd column when you have 2 available options

[Erumeldon]

From BGA wiki rules:

"One has moved on columns 2 and 3 and rolled 2,3,4,5. They decide to split as 2,3 and 4,5, and so should have advanced on columns 5 and 9. But this is not allowed; it makes them advance on four columns. They must pick either 5 or 9 to advance from."

Does the game actually allow you to choose? Because I think you can just press "advance on 5 and 9" and see what the game choose for you.

Don’t really understand your question but is not that difficult:

Example you already advance on 2 and 3 and you throw 2,3 4 and 5: the game propose those:
- advance on 5
- advance on 9

Or
- advance on 6
- advance on 8

Or
- advance on 7 and 7

When you only have one free option, you can choose wich your third option will be. So 5,6,7,8 or 9 then. Depend if the number isnt completed
