Create 10 matches in 10 seconds
This is the toughest achievement in the game but thankfully there's a pretty decent chance it will come naturally as long as you always move quickly. To force it though, you can wait until you have a larger level without anything restricting you, such as chained or frozen tiles, and then map out ten moves. You then will want to work your way from top to bottom, as bottom matches will throw off top matches. The other important thing to realize for this is that you don't need to wait for the matching chain to end before making another match. As soon as you make a match, go make the next while tiles are still falling. If it's easier for you, you could even use two hands to swipe very quickly, one right after another.
