Strategy for high scores:
1) use only three directions (in this example: left, right and down);
2) avoid as much as possible to place high numbers on top of lower numbers;
3) in the bottom row, position your blocks from high to low
4) now, you can keep your focus on the bottom corner with the low numbers, and gradually merge them towards the corner with the higher numbers
5) in doing so, you ultimately create space for a new row, once again keeping a strict order from high to low.
Good luck!
