In the early Levels hint letters (dark blue in color) are on the board and locked in position. These hints will give you help in fitting a word onto the board. When the game starts a Round timer (the Green bar) starts to go down (turn Red). When the timer is all the way to red, the round is over and all words are checked. If a word is placed correctly it gets locked in and turns to dark blue. If a word is placed incorrectly it gets rejected and sent back to the word list on the right. Fill in all the words on the Crossword grid and move onto the next Round. Complete as many rounds as possible in the five minutes allowed. A game ends when the overall game clock expires or you cannot complete a Level in 5 rounds.
