Spell words reading from left to right, using one letter per column. But be careful, some can lead you astray... Speaking of being led astray, you can long press on a word you have already spelled to return it to the pool of letters. Use the shuffle button to get a new perspective on the same set of letters.
Tap/click on letters to select them. Typing is also supported, where the "\" key is used in place of backspace. The settings button is used to create a new puzzle of different dimensions. Click on the numbers opened by said popup to cycle them to the desirable puzzle size (3-8). Since this is such a major update, I am sharing it as a new project. The old version, "Anagram Array Lite" is still up on my profile page for those who prefer a simpler experience.
