AN EASY TO PLAY, YET IMPOSSIBLE TO MASTER MULTIPLAYER WORD GAME! Each puzzle is built from a random word in the English dictionary, which means you never have to worry about running out of puzzles to play. Put your brain to the test as you try and solve puzzles in fewer guesses than your opponents, all while expanding your vocabulary with new words and definitions! CHALLENGE A FRIEND - Multiplayer is the heart of Letter Lock. Start by searching for a friend by username in the friends tab and challenging them to a game. Once the challenge has been sent, you and your opponent will both be trying to guess the same word. There is no time limit and you can come back to the puzzle at anytime if you're stumped (trust us, you might be sometimes!) Once both players have correctly guessed the word, or forfeited, the game is over and the person who guessed the word in the LEAST amount of guesses wins! COMPETE IN DAILY PUZZLES - Each day a new random Daily Puzzle is generated. The Daily Puzzle can be accessed from the Games tab by clicking on the PLAY DAILY PUZZLE button at the top of the screen. Everybody gets ONE attempt at the Daily Puzzle. Solve it in the fewest amount of guesses and you might just find your name at the top of the day's leaderboard! EXPAND YOUR VOCABULARY - Did you know that there are over 170,000 words in the English dictionary? It's impossible to know them all, but don't worry! After you finish each puzzle, you will be able to view definitions of the word that you were trying to guess straight from the dictionary. This is a great and fun way to learn how to spell new words, and discover how you can work them into your own vocabulary!
