Players solving all 16 puzzles will always get 1600 points as B. B for each puzzle will be calculated based on the following formula after the official time for the puzzle is over. B for Nth puzzle = 1600 * (Avg of Top 10 players's time of Nth puzzle) / [ Sum of (Avg of Top 10 players's time of all puzzles) ]	First 100 players to submit the puzzle will get C as 100 to 1
Final Leaderboard considers cumulative of A + B for each day.		Final Leaderboard considers cumulative of C for each day.
