This one is really easy to pull off. Just load up any expert puzzle and tap the "H" key on the keyboard for a hint for your next move. Click on either of the glowing tiles to clear the matching set off the board. If you don't have a keyboard, or just don't want to use one, you can open the "Menu" at the top left of the screen and click the hint key to apply the hint. The keyboard is much quicker though. Do this the entire puzzle until it's complete and you will unlock this achievement. It will take less than a minute to do it.
