At level 5640 i won the level 3 times. Each time the game would not let me move on to next game i

There is a glitch in this level meaning that the striped candies fire continuously and so the level hangs up. You could try one more time and try a different strategy to get around this. Be aware of the row that fires continuously and avoid hitting striped/striped combos into it. If you have no choice then swipe downwards rather than upwards into the two stripes. Do NOT waste gold on this level though. Gold is too precious, only use it to play on when you can see on the board that you definitely will win the level in the next move or two. For this pause before the your last move to assess the board before it disappears. The algorithms do work against players, but they can be beaten. Recognising how the algorithm is trying to trick you is the first step. One trick of the game is to get you on a win streak and then block it. Don't fall for this. Sacrifice your win streak if the board is hopeless! The next few levels are then more likely to be easier to pass I have found.
