UI Design for a "words" mobile game

This is the concept design for a fictional "words game".

In fact, a friend told me his idea on a game like that and he quickly sketched a rough ui prototype in order to describe the gameplay to me.

I challenged myself to take his idea one step ahead and actually design the ui of his game.

Time, letters, words, round number and points were the most important elements of the game. "Shuffle", "clue/help" and "double your coins" buttons should pop out too.

After doing my research on the ui of similar games to that I created my alternative.
