FOUR IN A ROW

A high-speed online game with balls, which is a little out of the rules of the three in a row standards, if only because here you need to put not three, but four balls in a row to remove the chain. However, unlike three rows, in this game you can make intermediate moves, i.e. if you notice two identical balls next to each other and the third one next door, you can rearrange it to these two. So, make lines of four or more balls of the same color. If for a certain time (indicator at the bottom) You didn't manage to remove any groups, then another row of balls will be added to the field. The game keeps you constantly in good shape, you can not relax, otherwise you will get a bunch of balls and lose.
