Ive just  finished the first round of flipwords, and on the last letter i had a 3 double word score letters in the word  and the word was worth 1075, and it included the last letter of the phrase. I had 13 turns left at that stage but when the last score was added on (6x1075) the bar was still going up but i lost out on the extra 3 turns that were awarded due to the high score of the last word. The bonus score was awarded on the 13 turns remaining rather than the 16 turns.
Why did it do that??
