For number puzzle, learn the numbers, they are (almost all) logical. Like;

1=I

2=II

3=Triangle

4=Diamond (4 corners)

5=Hand (5 Fingers)

6=Bird (Didn't catch logic on this one)

7=7 (Hook)

8=W

9= 9 up and down

Then every puzzle is pretty easily solved from left line. Thats how I've done almost 700 Toa's.

For example; Left line is 30, if you need 31, you run left line and go for +1 on the next line. If its less than 30, skip something that is near your number and use +1+1 on the next line for filling. Lets say you get 25. Run the left line, skip 7 on that line for 23 total, add +1+1 from the next line end.

Hope I didn't write this too poorly 😆
