Completion Bonus

When the game is completed, you will receive a bonus calculated in the following way:

Bonus = (End of Game Score / 4) + ((600 - Time Taken) x 25)

The following are the theoretical (zero time taken) maximum scores for each game rule:

Rule 1 - One Suit = 4160 + 6600 + 17,690 Bonus = 28,450 Total

Rule 2 - Two Suits = 6240 + 6600 + 18,210 Bonus = 31,050 Total

Rule 3 - Four Suits = 8320 + 6600 + 18,730 Bonus = 33,650 Total

Assuming a fairly decent completion time of 7 minutes (420 seconds) then the following scores are more likely:

Rule 1 - One Suit = 4160 + 6600 - 420 + 7085 Bonus = 17,425 Total

Rule 2 - Two Suits = 6240 + 6600 - 420 + 7760 Bonus = 20,025 Total

Rule 3 - Four Suits = 8320 + 6600 - 420 + 8125 Bonus = 22,625 Total
