Oops, timer on level 123 was 1:35, not 1:40... Passed it the third time, used a diamond+blaster, as well as a blaster+bomb & some "like-specials" combos. The board reshuffled about 30 seconds in, which pulled most of the stone jewels out of the pockets, making things a whole lot easier. Had one last glass in that side "outie" on the left, but luckily I matched it with just a few seconds left... Whew!
I earned forty gold bars from challenges, too. Expect to lose that soon (end of the next timed level, if not sooner!)
