Version 0.7 of LetterMiner is available to download for Macs running OS X 10.9 and above. Installation and gameplay instructions are at the LetterMiner website.

The new feature in this version is the game saves every word you mine to a file. When you mine a word for the first time, its text changes from white to yellow. Mining a word for the first time gives you a bonus. The bonus increases as you mine more words, but you’ll have to play for a while to see any increase in the bonus.
