Tips for level 84 by Andrew Martin.
This seems like a pretty darn hard level when you first play, but becomes (a bit!) easier if you follow these guidelines. I had all boosters on while playing this level ( I think it's a given to play with them in world nine)
You must NOT use a joker to pass this level. Makes sense to turn the joker booster off to save gems.
All the cards in the outside rectangle are doubled up. The scarab cards are in the corners, and ALL bottom row cards have chains on them.
The two mummy cards in the middle hide two jokers.
What you need to do is uncover the four corner cards and the mummy cards, while collecting as few other cards as possible, even if it means stopping a combo.
The mummy cards should be your first priority though.
You shouldn't have any problem getting a combo that clears most of the board and getting the scarab cards once the jokers are uncovered.
In a similar fashion as before, but the outer rectangle is now four cards deep, with the scarabs in the bottom row corners and all bottom row cards chained up.
The mummy card in the centre holds only one joker this time.
This is significantly harder than part one, but you must play in the same way. Hopefully you can uncover the centre cards (12 in total before you see the scarabs) by using as few other cards as possible, including the mummy card in the middle. It's inevitable that you WILL use other cards, but the less you use, the easier it will be to finish.
Hopefully you can score 2 or 3 card combos while getting the corner cards as you don't get many cards in this level.
Try to create a four card combo in order to pick up a scarab card after it.
If you managed to use NO other cards you will have 3 rows of 8 normal cards to choose from.
Leave the joker until as late as possible even if it means carrying on a combo, as you only get one.
If you're lucky in part one you shouldn't have to score very high in part two.
