Okay, this is actually pretty simple if you follow a few steps. For this achievement you need to make two snaps that are independent by moving only one tile. You're pretty much breaking up a series of tiles to make a couple different words. It may sound strange, but I'll try to illustrate.
First, you'll have a word, let's say it is:
Next, place a tile above or below the word, but not on the first or last letters of the word. It doesn't have to spell anything in particular. So for this example lets place a O above the U:
Then, on either side of the tile you just placed, we are going to spell out new two-letter words with the base word. In this case, I'm going to place I's on either side of the O, so I can spell 'IT' and 'IN':IOI
You'll notice, however, that the 'IT' and 'IN' don't score any points. This is because that O in the middle is misspelling everything. All you have to do now is remove the O and you'll create and score two new words just by moving one tile:I
There are several combinations you can use, I just used the above as an example. Check this site for a list of 2-letter words in Wordament: http://yvi-prod-eus-website.azurewebsites.net/two-letter-wor...
