Interstate

Interstate is a trivia game about the 36 states of Nigeria. There are two decks, a green deck with the name of one state each, and a red deck with questions. The green cards are dealt out to the players. Each player picks one of those cards and places it openly in front of them. A red card is then flipped up and each player must in turn answer that question in relation to the state on their card. If they manage to do so, they can discard the green card; if not, they have to take it back into their hand. Answers can be challenged; but if you wrongly accuse someone of giving a wrong answer you have to take their green card. The first player to get rid of all their green cards is the winner.
