Completion Bonus

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

Bonus = (End of Game Score / 4) + ((300 - Time Taken) x 10)

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

Rule 1 - One Suit = 2600 + 3150 + 4437 Bonus = 10,187 Total

Rule 2 - Two Suits = 3120 + 3150 + 4567 Bonus = 10,837 Total

Rule 3 - Four Suits = 3640 + 3150 + 4697 Bonus = 11,487 Total

Assuming a fairly decent completion time of 2:30 (150 seconds) then the following scores are more likely:

Rule 1 - One Suit = 2600 + 3150 - 150 + 2900 Bonus = 8500 Total

Rule 2 - Two Suits = 3120 + 3150 - 150 + 3030 Bonus = 9150 Total

Rule 3 - Four Suits = 3640 + 3150 - 150 + 3160 Bonus = 9800 Total
