Universe Slapjack
Once the screen shows green, hit a key fast and get a point.
A bunch of players connect to the server. (One player per window.) The screen is yellow for a random amount of time (say 1-10 seconds). When the screen turns green, the first window to hit a key gets a point. The others are locked out until the next time the screen turns green.
- Show points on screen.
- Any key hit in a window scores for that window.
- Only one point per green screen.
- No points can be earned when the screen is yellow.
