The jar only takes in glowing pieces & sometimes it takes 2 times to match 4, even the same 4 pieces!
Kind of like those orbs. THEY take a match 4 or more, more than once, too!
Last report, i've got it down to only 18 left, to fill the jar! *On payday, I'm buying some extra moves & finishing the VERY challenging level 362!

Two things I've noticed. Whenever there are 4 in a row (horizontally) directly opposite the jar, it takes pieces in.
Also, from accross or below, if the pieces are glowing, the jar takes some in.
Let's keep a running total. That is, so far I have gotten down to 20 to go in the jar!
