Not difficult at all! As long as you know the basic rules of the traditional minesweeper. Each field can be one of three different things:

boring non-mine cell, which we don't really care much about

helpful non-mine cell, which we like a lot, because it tells us how many mines are close by

dangerous and scary mine cell itself, which we can't reveal until the veeery end of the game or else we are blown up into little pieces and lose.

As a little helper, we also have the flagging option - if we're sure a field is a mine, we can mark it with a flag to not blow it up on accident.

And what's the goal ? To find all the scary mines as fast as possible - after all, noone likes an unexpected explosion right under their feet.

Colisweeper works just like that as well! To imitate the "click" of a mouse on a computer, we add a substrate to the cell of our choice and that way we start a reaction
