Letter Tangle is free on App Store

Letter Tangle is a new word puzzle game for iOS built around hidden themes and connected letters. Each puzzle opens with a cryptic title that hints at the theme. You then fill in a group of related words that fit it. Right now, the $4.99 one-time unlock for the full game is free with an App Store Offer Code.

It suits anyone who likes word games, themed puzzles or cryptic clues and wants something to solve on an iPhone or iPad. The game has no subscriptions.

The unlock is permanent, so once you redeem it the full game stays in your library after the deal ends. The number of redemptions is limited, so claim it soon if you're interested.
