The lightbulbs show how well you're playing at the level you're at. Fulfill the goals in fewer moves to get more lightbulbs and get a reward!

You get points for each block shape you place on the game field, and you get more points for each block removed from the game field. And you get even more points for scoring combos (several lines, columns, and/or sections removed in any combination) and scoring streaks (removing lines, columns, and/or sections in a row with consequent moves).
