In One Line Crossed, your goal is to match monsters and collect rewards. At the start of the game, small monster pictures appear in the top-left corner of each grid square. As the game progresses, larger monster images appear randomly in the squares. If a large monster matches the smaller one in the corner, the square lights up with a glowing effect.
To win, you need to collect 4 glowing squares in a single line, which can be horizontal, vertical, or diagonal. There’s also a special bonus: the pin button allows you to mark a square even if the images don’t match, helping you complete your winning line faster.
Match monsters, light up the board, and win coins!
