score = previous score + (5 + 10 * Chain Number)
Chain Number equal amount of cards, collected one after another one, without interruptions.
The goal is to create the biggest chain possible in the shortest amount of time.
Time Bonus: the number of seconds remaining. Max = 600 points (10 minutes = 600 seconds)
score = previous score + (Bonus + Time Bonus)
Max score = 4,245 (one chain, which will cover all cards) + 600 (impossible time bonus) = 4845.
