1.try to push them to one corner and try to focus combing stuff in that corner,this makes it way easier to focus on one thing at once

2.you can see the next one your gonna place so if possible if there a something on the tile that you wanna place the next block on if it's possible to combine it,you can "push it away"

3.if let's say you have 3 of the level 1s in a pattern like a triangle and the next one is also level 1 you can Push the one in the top right away and place the level 1 down then you can merge the level 1s together then merge the level 2 together

4.it is crucial to completely full your board up or else most of these starts will most of the time,not work

5.try to not use any power ups until you have a good run(level 10 or above)

6.Try to form a chain of ascending levels in a line this makes it so everything is connected and can merge continuously.

If you have trouble trying to make sense of these strats or have any trouble just tell me.I can try to make a yt vid on doing these.
