- At the top of the screen you can see the main color — your reference for the search.

- There are four buttons below, each with its own shade of red.

- Your task is to carefully compare the colors and select a button that completely matches the main color.

If you guessed right:

- you are moving to the next level;

- the colors of the buttons become even more similar to each other — the game becomes more complicated.

If you made a mistake:

- you are burning out one life (out of three available ones);

- you stay at the same level and try again.

- The game continues as long as you have lives.

- If all three lives are exhausted, the game ends and you see the final score (the number of completed levels).

- You can start over: the game will start from the first level, and the score will reset to zero.

- Important:

- take your time — concentrate your eyes, compare the shades;

- With each level, the difference between the colors becomes less noticeable.
