Gets annoying pretty fast

Normally I like these puzzle games but this one annoys me. Just one drop of the gems fills up a third of the board. Two drops the game is pretty much over, unless you clear up most of the board each time. It wouldnt be so bad if I can get the gems to where I want. But the touch is terrible. I think its because of the triangle shape.
