Level 164 is to put out the fire in 60 moves. There are 2 areas of flames lower left and right that are blocked in by crates.

Level 165 is 98 moves of digging down 12 blocks deep. There are rows of black jewels, white colour match jewels, and a few of those special ones that you have to make special jewels out of them to get rid of them (what are they called?!)

Level 166 is to put the fire out in 2 mins 30 sec. There's nothing keeping the fire contained, 20 flames to start with, and it seems to move quickly. Matching has been a problem for me on this level, even after a couple of seconds it reshuffles, and typically, just as you're about to make a match right next to the flames, the flame spreads to one of the ones you're going to swap with! Grrr!
