Bingo Item Pools

How The Pools Work

Each pool has two kinds of entries:

• items: a flat list of materials. Each item listed is a potential card slot.
• categories: named groups of related materials. A category resolves to a single random item from its list when a card is generated. This prevents a card from filling up with several near-duplicate items.

Sampling rule: every pool entry, meaning each item and each whole category, can be picked at most once per card. A category counts as one entry regardless of how many materials it contains.

Difficulty Merging

When a player picks a non-easy difficulty, the chosen pool is merged with the pool one step easier.

• easy uses easy.
• medium uses medium + easy.
• hard uses hard + medium.
• grindy uses grindy + hard.

The nether pool is not a difficulty. It is a separate yes/no option, and when the nether is enabled its pool is added on top of whichever difficulty pool is in play.

Some category names appear in more than one pool, for example BRICK or WOODEN BOATS in both easy and medium. When merged, these stay as separate category entries, one per pool, so a higher difficulty card can roll one item from each.
