Alice in borderland: Solitary confinement

Every round, you are assigned a symbol: club, heart, spade, or diamond. Right click your paper to display your symbol for others to see. However, you cannot see your own symbol. At the end of every round, guess your symbol. If you get it right, you move on to the next round.

Among you is the jack, selected by random. The game ends when the jack dies, and the prize is split among the remaining players. The jack wins if everyone dies, or if the jack is the last remaining player. At the end of round 20, if the jack is still alive, the jack wins.

Advice: Ask others to tell you what your symbol is. Use /me to speak during the game, /msg will be disabled.
