It took me a while to pass level 10 too, I have to say but eventually it worked out I'll have to tag our wonderful players here, I'm sure they'll have plenty of good tips for you!
Okay, you have one more level to go here. You got this. The video is a good place to start. I watched it to remind myself of the level and I think I have a few more moves/pointers to add.
Use regular candies with the rainbow candy down on part 2!
1. Make matches using red or orange with the rainbow candy and line them up so them end up at a caged candy. This will give you 5 candies in a row aka a color bomb! Here is the move that could have been made. Basically you want to think of "connecting the dots" of regular candies to make.color bombs and coloring candies. Rachel's rainbow is about being a tool for that here in my opinion.
2. Use regular candies to jump over the hole here and hit these color.bombs! If you can move a rainbow candy toward the color bombs here when you switch it, it will jump over the hole and hit these bombs. I'm not sure if it would work by switching 2 rainbow candies but you could definitely do it with a regular one.
I hope this helps. try working the rainbow with regular candies or even just use regular candies to make color.bombs and then use the rainbow candy with the color.bombs. hang in there! Good luck! 🙂🤗🐳
