Elasticity, updated to version 1.0.1, is a game of tactics and good luck. When three or more bubbles of same color form a vertical or horizontal line, they disappear, allowing bubbles above them to fall down. You get score from each row you remove, and when the bonus bar on right side of the playfield overflows, you advance to the next level. You should try to get as high score as possible. (Chain reactions give a lot of score).
You move a bubble by swapping it with the one above, below, left or right to it. If the move does not form any rows, it is not valid. When you run out of moves (e.g. cannot swap any two bubbles to form any row), the game ends.
