Excellent Connection - Words is a free one for iOS and Android that uses unlockable hints to help you fill in the blank letters.

There are over 300 puzzles in the game.

Each one starts out with a grid of draggable letters and an incomplete word.

At the top, a list of associated hints - synonyms, antonyms, or generally related words - are listed for assistance.

Only one hint is displayed at first. The less hints you use in any given round, the more points you get.

Excellent Connection is free. The only downside is the use of both banner and pop-up ads throughout the game.

If you're interested, you can download it on the App Store, Google Play, or the Amazon Appstore.
