Question: Raffle formula

[cunningrat]

Can you please let me know what is the formula behind the "Raffle" checkbox in the trade generator?

[Grauenwolf]

Imagine that you had a box of raffle tickets. You give some tickets to each type of good:

• Goods with *: Always available
• Good with no mark: Only 1 chance
• Other goods: 5 chances plus 20 chances per matching remark (trade code)

The 6 raffle tickets are selected (drawing another ticket if the same good is chosen more than once).

---

For non raffle mode the rule is:

• Goods with *: Always available
• Matching Trade remarks: Always available
• Other goods: Randomly choose 1d6 goods

If you read C# code, look for line 190.
