The game is quite simple if you understand the rules. Your goal is to guess which mathematical equation was hidden. It consists of the same number of characters as the cell is in each line of the playing field.
Try entering any equation on the first line. For example 5+8+9=22. Click on the enter button. You will see that all cells have changed their color. Some are green, some are yellow or grey. These are hints.
Green color will mean that you guessed the correct number or symbol. That is, in the hidden equation, this symbol is located in this place.
The yellow color of the cell means that such a symbol or number is in a hidden mathematical problem but is located somewhere in another cell. Gray color will mean that there is no such symbol in the hidden expression at all.
With the help of the information received, continue to make new guesses until you guess which equation was hidden. But remember - you only have 6 tries to do it.
