This online game is similar to a puzzle whose goal is to put together similar blocks to make them disappear. Deleted all locks you go to the top level. The scoring system of this game is based on a concept similar to par in the game of golf. A default solution is available for each tier. By resolving the level with the same number of moves as the default solution, you’ll get a score of 0. The default solution may not be the best solution. You can then beat par and get a positive score.
