Let me know if there are any levels I should add, or if there are better ways to do these levels.

Level 18: Start with the right dot and move in a clockwise direction. Note that this works for my tablet, but the level may be different for other devices.

Level 20: Get the two dots on top of the 0 (get the right one first) then go over the 0 counterclockwise. On the last dot of the 0 go right (wrap around the screen) and go over the 2 as you would write it. Triple tap to turn left.

Level 25: (Found by jozi1123) L R LL R LLLLL R

Level 29: Start with top, move clockwise until all dots are at the edges. Then start with the left dot and move clockwise.

Level 33: (Found by jozi1123) Move the N to the second E final position. Move the R to the final G position. Move the N to the top middle. Move G to the final R position. Move the N to its final position. Move G to the second E final position. Move the first E to the top middle. Move R to bottom left. Move G far left. Finish.

Level 34: UU L UU R (7D) LLL D RRRR U R

Level 37: This is likely not optimized, but it is pretty fast: RRRR LLL RRR LLL (6R) LLLL (5R) L (5R) L RRRR (5L) RRRR LL RRRR LLL RRR LL RRRR LLL RRR LLL RRR LLL RRR Or you can think of it as starting with the right and doing this many, then doing left: 4 3 3 3 6 4 5 1 5 1 4 5 4 2 4 3 3 2 4 3 3 3 3 3

Level 45: M LLL MM RR M LLLL RRR

Level 50: (Found by jozi1123) Spiral outwards counterclockwise around the center, starting at the block above the middle.
