Completing a game in Classic mode unlocks Time Attack mode, where you are timed as to how quickly you can solve five puzzles. Upon completion of a Time Attack, Survival mode becomes available. Survival gives you a time limit, requiring you to solve as many puzzles as you can within three minutes. Each guess that brings you closer to solving the puzzle, as well as each correct guess, adds time to the countdown, which extends gameplay. Each incorrect guess, such as a word outside of the range, a misspelled word, or an invalid word, results in a time penalty which reduces your remaining time and brings you closer to the buzzer.
