Wordbrain is like hide-and-seek, but with words
(Windows Phone Central)

Wordbrain is a challenging puzzle game for Windows 10 Mobile in which you need to build words, hidden in a stack of letters. The free game has 580 word puzzle levels that progressively become more challenging and supports 15 languages. You build the words from square grids of letters, much like you would with Wordament. The key difference being that you are searching for a much shorter list of words. The mechanics of gameplay takes a little time to get used to but not to the point of frustration. Overall, Wordbrain is a fun way to burn a little down time and exercise your powers of observation and spelling. ...
