I've been having issues to where it doesn't register some matches that make a nine, and it seems to do it after rotating. I'm on a friends laptop, and it kinda sucks so it lags, dunno if that'd have any bearing.
But, after rotating, I put a 2 next to a 5 and a 2, making 9. Didn't register, turned, dropped a 3 next to a 3 and a 3, didn't trigger. Rotated, dropped a 2 on a 3 and a 4, no trigger. And, after that, I rotated and placed a 3 down, and it was touching just one other 3 and it triggered with the two threes, and that made me wonder if the reds were being double the amount. I put a 3 down on a red 1, a 1, another 1, and a 2, (which is 6, 7 if the red 1 was doubled) and it triggered. I then tried dropping a 3 on another red 3, and it didn't trigger. Something seems messed up with the rotating, thinking maybe based on the performance? I dunno, kinds sucks to drop things and not have them trigger properly >>
