What mode did you do it in? I have def done 3 in a row on beginner and no achievement. Turning tile inbetween each chain to set up for the next one though does that break it?
Does it have to be 3 in a row without touching any tiles from the first chain begins?
EDIT: got it about 2 minutes after posting, did it in freeplay and saved U tiles so I had 3 on top of each other, that way I wouldnt have to touch anything once the chain started
