Groups

Groups are a way of biasing the card generator to select fewer closely-related categories in the same bingo card. They are defined in the Category List JSON.

The generator will prefer to not reuse groups when possible. However, if all categories have been exhausted before a card is filled, the generator will reuse groups that were previously marked as used. This ensures that a legal card is always possible regardless of category groupings.

If a completely unbiased card is preferred, this behaviour can be turned off with the Allow Similar setting.

Groups are automatically color-coded for easier identification. This color is determined by the number of groups, and cannot be set independently. Selection tools are added for easier manipulation of groups when refining categories.

Groups are only used during generation and are not saved to the final card.
