Words Builder HD is an Android game that combines the elements of "Scrabble" and "Jewels." The game challenges players to build the maximum number of words from any adjoining letters, including diagonals, within a given time frame. The game requires not only speed but also tactics and the ability to calculate the combination of a few moves ahead.

In the beginning, players have three minutes to compile words. For each correct word, they get extra time. The longer the word, the more seconds they will get. The game uses a dictionary of words from SOWPODS, and players can contact the developer to add support for their language in the game.
