Some tiles have two letters or unique characteristics. Each tile can only be used once per word. To make a word, select any tile and drag through adjacent or diagonal letter tiles to make words. Words must have at least three letters and cannot be abbreviations or proper nouns. In Wordament, the goal is to find words by highlighting adjacent or diagonal letter tiles in sequence. Through the service, the game gives out achievements and the associated Gamerscore as reward, even if the user is using a non-Microsoft device. The game had the distinction that allows optional access to online leaderboards through Xbox Live service from all platforms, including iOS and Android devices. The game was relaunched in June 2017 with two new game modes, Crosswords and Word Twister (first known as Jumble). Microsoft Ultimate Word Games (known as Wordament on iOS and Android) is a word puzzle game published by Microsoft Studios, first released for Windows Phone as 'Wordament' on April 24, 2012.
