Players from different divisions can play on the same card. However, if players are in different pools, they can't be placed on the same card.
Use card assignment rules to control how divisions are mixed. After you've created rounds, follow these steps:
Go to the Cards tab
Tap Edit rules
Scroll to Can players from different divisions be on the same card?
Select from the dropdown:
Mix divisions when necessary (preset) — players from other divisions are mixed in only when needed to fill cards evenly
Mix divisions — all cards include players from a mix of divisions
Never mix divisions — divisions are always kept separate
Important: If selecting Mix divisions when necessary, you'll need to decide which divisions can be grouped together. Use the Move division to this group button to group divisions that should play together.
