Logic Game "Laime" (luck)

This is my first serious project with c#.
Code might be bit chaotical
2 players can play this or you can play with computer.
Every player starts with 24 points.
Then you have 3 sec to remember 18 numbers where every one of them has its own meaning.
1-9 enemy looses his points.10-12 you gain +1 point, 13-15 you loose -1point , 16-18 nothing happen you loose your turn.
I will try to redo it in another language and modify it, feel free to tell me what you think about this game.
