. I am stuck on level 7840.

Hi and welcome to the King Community

Level 7840 is classified as a nighmarishly hard level so you can expect to lose some lives before you manage to pass it. This is an orders level, you have to collect the licorice and cherries to complete the level. To begin with you can only make moves in the middle part of the board, use stripes and stripe combos to clear the outer sections. Once there is space in the sides you will get stripes and wraps dropping from the dispensers at the top. Switch wraps together or switch stripes and wraps to work your way down the board. Stripe/wrap combos are the best as they will uncover the fishing floats at the bottom of the board, once you begin to get fish they will target the licorice. The fish will clear the licorice in the middle section of the board to get the cherries in that section to the exits.
