This chameleon candy timed level isn’t so difficult. Make matches at the bottom as often as you can, and grab the +5s that appear on the screen at the top. You’ll slowly crush your way down into the meringues and get the three additional +5s at the bottom. Then make as many wrapped and striped as you can to push you over the target score.
If you run into any difficulties, just make match-3s at the top until you bring some +5s down and get extra time on the clock. An easy level to beat.
In Candy Crush Saga level 313 you need to score 20,000 points within 45 seconds.
The board in level 313 has some gaps which means that it is more difficult to make matches. There are also rainbow candies trapped in marmalade and multi-layered meringue blockers to make things more challenging. There are some candies with +5 which are worth trying to get so that you have more time. You will also score more if you can make special candies. In fact the key to winning level 313 is probably to make as many special candies as you can and activate them as well as working on matching the +5 candies. Some people say that it is better to wait to activate special candies until the end of the time as they score more, but it can be best to activate them as soon as you get the chance because you may miss the opportunity. It may also help to bring down more +5 candies.
There is some luck with timed levels. You will need to be really quick and it is worth considering whether you can be quicker playing it on a PC or tablet or phone, assuming that you have the choice. You may find that you are significantly faster on one, compared to the other.
You can buy an extra time booster as well as a color bomb and wrapped and stripe candy. These could help but it will depend on whether you have a lucky board to start with and where they are placed on the board. During game play you will probably not find that any of the boosters are that useful and you will not really have a lot of time to consider which to use, when and to activate them.
