It's only building squares! XD First, there is a ratio/pattern of pieces coming, in the beginning small pieces, later harder more space killing pieces and when you're more or less screwed at the end erase pieces will occur. First of, do not let you be dependent on one kind of piece coming, let's say a small corner, for all your loopz because then you will soon lose. So build a loop that is awaiting a small corner or a small straight, another that is waiting on a larger corner or a straight three-piece and so on... I have like three loopz in work at the same time awaiting different pieces.... the way to get points. And when a large U-shaped piece shows up, I always put it alone in the corner to await a second one to complete the loop. There is one piece, the largest one, that sometimes should not be placed since it will ruin all loopz in work, then just let the time end and get rid of it that way. For extra space, build loopz inside loopz. In the end, don't give up, place as many pieces as you can into the maze for that extra end points. Sometimes, while loosing things opens up from a series of three erase "pieces" in a row and your on the track again! Lucky! My best have been 27k, 31k and now 38k. Am kind of tired of the game right now, but will return for some more loopz madness very soon muhaha! Play a lot of times, for hours in a row and your skills will amplify!
