The images refreshes every 10 seconds or when you solve a problem.
Do you really think that 10 sec is enough to solve this kind of problems !! . It is really not enough , I keep trying my best was to solve 2 words and when typing for the third the image changed , and the words was really short , imagine if when the words is long ! . I really do not think that 10 sec is ideal to solve this puzzles manually , No way ! .
Yeah, what a joke, no way we can put the answer in before the image changes.
