Rembrandt en Tijdgenoten

Rembrandt en Tijdgenoten is a trivia game. Players move on the board and answer questions in 6 different categories. Rules are simple:

You've answered the question correct:
- you score a "+ chip" of the category's color
- if you already have a "+ chip" of that category, you can flip one of your opponents "+ chip" over to a "- chip"
- if you have a "- chip" for that category, you can turn it over to a "+ chip"

You've answered the question wrong:
- you don't get a "+ chip"
- if you have a "+ chip" for that category, you'll flip it over to a "- chip"

Game ends when one player has 6 chips (either + or -). The player with the most "+ chips" wins.
