The rules are clear, which ever is yours, you add or subtract that.
You use your birth month, and to keep it less complicated, I piled the months into categories of 2. Those two groups are the months, which were categorised in their season.

January: - 2
February: - 2
March: + 2
April: + 2
May: +2
June: +2
July: +2
August: +2
September: -2
October: -2
November: -2
December: -2

Spring and Summer (March-August) win at 1000
Fall and Winter(September-February) win at 0

Once we reach a goal they win and we restart.
I will also keep track of the wins, (as much as I can)
And I hope this doesn't get locked~

See ya at the finish line
500.. go!
