I'm looking for a match 3 type game that has a timer that counts down as you play. With every match you get a small amount of time added to your total time. The more matches you make the longer you get to play.
Most of the ones I've found don't offer a timed mode that I'm looking for. Most just give you a minute or 90 secs and you try and get as many matches as possible (i.e. Bejeweled Blitz, Jewel Craft, etc.)
