(11C) Skat scoreboard with money counter

[Michael Zinn]

This is a scoreboard for Skat (3 player game). It also accounts for money that the losers have to pay to the group's cash box.

USER GUIDE
1. Set the calculator to USER mode
2. Init with GSB 9
3. Select the currently playing player with A/B/C
4. When the game ends, enter the score and then press D (LOSE) or E (WIN) from the perspective of the playing player.

DISPLAY
The display looks like this: #.SSSSMMM where # is the player number, SSSS is the score and MMM is the amount of penalty money in cents.

PENALTY MONEY
If a player wins, the other two players get the points as penalty points.
If a player loses, they get the points * 2 as penalty points.
Penalty money is score divided by 4, rounded up to 10 cent increments.
