As you can see, there is space containing more than 100 hex-blocks. What you need to do is to put the following blocks with different forms to the space. When one line in the space, paralleled or perpendicular,or other lines is filled, this line will be eliminated. As a result, it can save space for you to continue to put other blocks. During this period, remember to keep a larger space in case some big blocks suddenly appear. Otherwise, the game will be over.
