Guess a four-letter word selected by the computer with as few tries as possible. For each guess MasterWord shows how many letters you have guessed correctly and how many others are right but in the wrong position. There are 500 puzzles included. Each has three different levels - the harder the level, the higher is your potential score. As each level increases in difficulty your score increases but you are always racing against the clock. If you finish more quickly you will get a higher score. The top ten scores for each game are recorded in a High Scores table.
