"20"

Our game is a strategically single player game. And according to the constraint, the all
components for the game should be money (coins, paper, etc). The game material is
coin. Coin is a small, flat, (usually) round piece of metal or plastic used primarily as a
medium of exchange or legal tender. It is easy to use and bring. For our game, it is
inspired by the game that we have played in our childhood. When I was a little girl in
primary school, I always like to play something to have fun with my friends. At that time, coins are the most convenient tools for us to bring and play. And also this game can be played for single player, it is full of competitiveness and strategically for everyone to play.
