How to Get the 80K Score
Just keep making lines. You get bonuses that increase each time you complete a line. They are small at first, but eventually you will be getting 5k+ points for each line you make.
Don’t even pay attention to the items that are in the line, just focus on completing the line itself.
Also, try to land the ring at the top kind of like the critical area for the menko game (if you play it).
