This game challenges you to reproduce a code consisting of letters. The code starts at a length of 1 and continues up to a length of ten letters. To increase difficulty in higher levels the entry-screen changes the letters positions randomly. With each letter you type a sound is played. Correct answers add up to a melody, while any wrong entry ends the level. You may retry the same code as often as you like. At the end of each level you can choose to continue on the same level, go on to the next level or reset the game to start at level 1 again. A fun game for all ages which also trains your memory!
