There is very definitely a problem with scoring in Lost Cities. In the game I just played I had in Red:
$$$2-5-6-8-9-10
The computer gave me 100 points. This is definitely incorrect. the numbers total 40. 40x4= 160.
160 plus the 20 point bonus is 180. The program shorted me by 80 points! (I did win anyway however
Are you aware of this glitch?
