Tie Breaker

In the event of a tie at the end of the game:

  • The scoreboard has an offest column which tracks time to reach the a score.
  • We do NOT accumulate time, it is only the quickest to arrive at that score.
    • Meaning, you can win by solving challenges 1-14 on the 2nd last day, and then be the 1st to solve 15.
    • Don’t feel you have to solve challenges 1-14 at midnight to win. 
    • But if you are tied, going into the final challenge, get on it as soon as challenge 15 is released.  Good Luck!
