Level 266 is the sixth level in Holiday Hut and the forty-sixth candy order level. To pass this level, you must collect 5 striped candy + striped candy combinations and score at least 25,000 points in 50 moves or fewer. If you have extra moves left in this level, Sugar Crush will activate striped candies and score you additional points.
The chocolate is not the difficult blocker in this level. The bombs are impossible to free from once they come out unless you demolish the bomb and move it towards the center at the same time.
Try not to trigger any bombs from the candy cannon until you have fewer than 15 moves left or when you're almost finishing your last combo.
To stay away from the bombs, try to make striped candy combos at the top half of the board only. If any bomb spawns, there can be tons of trouble, since more bombs can spawn indefinitely!
