@@Kamiliau7890 Block meter is a thing that gets triggered whenever you get hit by an attack, when that happens you can get 1, 2 or 3 points of block, when the meter gets full by getting 8 total points, you block an attack, you can also block multiple attacks if there is 2 plants in the same lane, or if a chain reaction occurs, after blocking you get one of the 3 super powers your hero has, you can choose to play it right now for free, or play it later, but it will cost you 1 brain/sun to play it, after blocking 3 times, you can't block anymore.
