Been toying with this for bull practice with mate
ONLY BULLS SCORE
D bull = 2 points
S bull = 1 point
closest to the bull goes first
each person throws 1 dart with bad arm at the bull ( If you hit a bull then that score counts).
You have to get 3 points to become a killer.
once you have 3 points all excess point's come off your opponents score untill they are BELOW zero making them dead.
e.g. I have 2 points and opponent has 1 point. with my first dart I get a double bull (2 points).
One of those points makes me a killer and the spare point comes off of my opponent making them zero but still in the game.
The next dart I miss the bull alltogether (no points)
With the third dart I get a single bull(1 point) that point comes off my opponent who was on zero making them dead.
MUGS AWAY
I call this KILLER ON THE BULL
Its fast and great bull practice
but most of all FUN
Hope you will try it.
Hope I explained that clearly enough that was harder than I thought.
