Description

Move your finger along the matrix. When your finger is over the circle under which the symbol pixel is hidden, a beep will sound. Using these sounds as a clue, try to guess the symbol.

To check your guess, click on the text field at the bottom center of the screen and enter a symbol. If you guess correctly, the symbol will become visible for a while. After it disappears, the game can be continued.

If you don't guess correctly, the symbol you entered into the text field will disappear and you can continue trying to guess it.

If you can't identify a symbol, click the button in the lower right corner and that symbol will be shown to you. Soon the symbol will become invisible and will be replaced by a new one.

To make the game easier, you can click on the button in the upper right corner of the guide to exclude numbers from the list of symbols.

You can mute the sound by clicking the button in the top left corner of the guide. In this game mode, the matrix circles change their color at the moments when there is a hidden symbol pixel under your finger.
