Spades Scorecard

This is a standard scorecard for a real game of spades. Game is up to 500 points. Double nil points are 200, nil points are 100. On your 10th, 20th, etc. bag, team will lose 100 points. Successful bids are 10 points each, with 1 point for an overbid. Underbid penalty is 10 points. If anyone wants me to add game customization to the application let me know through the comments or email. PLEASE NOTE: This is not an actual game of spades. This only keeps count of the score when your playing a real game, not a virtual one.
