In Candy Crush Saga level 510 you need to bring down the ingredients and score 50,000 points.
You have just 35 moves on level 510 and 4 ingredients to bring down. There are five-layered meringue blockers in the way and the middle of the board has no way down for ingredients so you do not want them to fall there or else they will get stuck. There are no nasty surprises, such as bombs dropping from the top, but it is still very difficult to get even one ingredient down in the number of allocated moves.
Making special candies is key. Use vertical stripes to attack columns of blockers and better still striped and wrapped combinations. A color bomb and striped candy could be really useful as well, not only at clearing the blockers but at getting the ingredients down. There is a lot of luck in this level as well, so be prepared to play it a lot of times before you manage to solve it. Just keep looking for the chance to make special candies and remove the blockers to get the ingredients down.
Having some boosters at the start of level 510 could be handy. A color bomb could be good if you can combine it so perhaps a wrapped and striped booster with it might be best. There is not much else, apart from a coconut wheel that could be much help on this level, you just have to keep persevering at it and hoping that you will get the right combinations of candies to make those special candies so that you can win.
