Tips for level 551 Candy Crush Saga
This level has 3 conveyor belts, all moving from left to right and the ingredients have to leave by the three center columns.
Here the conveyors will help you enormously, especially if the nuts come down at the side of the board.
Just make matches under the nut to let it fall onto one of the conveyors, then let it move along until it's in position over one of the exit columns, then match below it to drop it down off the conveyor and out. Ready for the next ingredient to fall.
