Tips from Adrian.
The main thing with 90 is to keep the fruit (ie the things you
are collecting!) in the MIDDLE when they get to the
right hand frame
Getting then in the right place and not trapped just one or
two "squares" above the exit is the trick ...
Think/plan these last couple of moves when it gets near to
the exit - a vertical line blast would be good but you can't
make one on this level (the system can, by chance!) ...
so look for other specials /combos if you can (remember,
Two striped candies will blast both ways, even if BOTH are
the same - in this case both would be horizontal.
If it does end up left or right of the exit frame try and
swap it back ASAP as it's really difficult when
near the bottom.
Remember also that a match in the right frame will
advance the fruit at least 3 places and possibly lead to a
mini-cascade, so make moves there if you can rather than
in the left columns
