Fun puzzle mini-game - Super Blocks

This game has a great idea, with simple rules that are highly intellectually stimulating, especially testing your ability to oversee the whole situation. It is also quite popular on foreign forums, and once you play it, you can't put it down!

Operation method: First click on the square, then click on the destination to move. If there is an obstruction in the route, it cannot move. If four or more identical squares are connected in a line, you can score, in horizontal, vertical and diagonal directions. Note that every time you move a square, there will be new squares added. The key to getting a high score is to keep the total number of squares in a relatively small state!
