Trebuchet Card Game

Trebuchet  is a card game for two played with a standard 52 deck. build your house of cards while your opponent tries to knock them down with thrown cards. Steal them back after switching roles! Force your opponent to reach into the reserve pile, but better leave enough for your turn!

A diagram of a typical play space.

After guessing which number my opponent wrote down, it's time to knock down their houses of cards, with one thrown card at a time.

My opponent already used half the two cards in the deck. Time to reach for some of the special cards!

I guessed 'two' was my opponents hidden number, but that wasn't it. They can't build a card house with only two cards...so they reach into the special card pile too.
