When you click on a row and you delete 3 in a row. Don't look everywhere, just look around the 3
jeweled you just got rid off, and you will see quite a few jeweled that you can erase. After, go at the bottom, 99% you will find a lot to erase.
At level 18 and about 180,000 points it told me
that a new level was unlocked and available from
Main Menu. Click on the "?" and Classic then
changes to Twilight. On this level when you line
up 3, 4, or 5 the pieces alternate the way they
fall. One time they will fall from the top then
the next time they come UP from the bottom.
