The blues will take care of themselves here – just concentrate on combining a colour bomb with a striped candy to make a dent in the huge order of striped candy you need to get,
If you manage to do that twice, you’ll be home and dry – if the tornado doesn’t set off the colour bomb in the middle, mix that with a striped if you can. Otherwise you’re still going to have a lot of striped candy to make to complete the level. Use stripes to set off stripes, work through the meringue so you have more room to make the combos and make good use of the two marmalade coated stripes to get through this.
The orders that need to be made in level 438 are 30 striped candies, one striped and color bomb and 90 blue candies. The board has a toffee tornado on it, a selection of different meringue blockers and some striped candies and a color bomb at the bottom under the blockers, encased in marmalade.
Without making a striped and color bomb combination at least once, you will not be able to complete this level anyway so this requirement may not be as unfair as it could seem. Play the game by making as many striped candies as you can. Unblock the lower areas when you have no option to make the striped candies. Then look for opportunities to combine them either with color bombs that you make or the one on the board. If you achieve this, then you should find that a lot of blue candies and striped candies will be activated and it will be much easier to complete the level. You may need to do it twice to remove enough striped candies to win though. There is not much you can do about the toffee tornado, just hope that it removes useful pieces and does not ruin any good matches that you have been lining up.
Starting with extra moves could be helpful as could a color bomb. The other boosters available for level 438 are probably not as useful though but could help in specific circumstances.
