The game is Minesweeper type:
When you click on one box, you get a number that identifies how many there are around hipotenochas:
        Be careful because if you click on a square that has a hidden hipotenocha, lose.
        If you think or have the certainty that there is a hipotenocha, make a long click on the box to highlight it.
        Do not do a long click on a square where there is no hipotenocha because you will lose. Win once you've found all hipotenochas.
