How do you solve the itouch app brain teaser?

Answer 1

for this, use the squares as coordinates; eg. (1,2)

3x3 grid:

(1,3) (3,3) (1,1) (3,1)

4x4 grid:

(1,4) (2,3) (3,2) (4,1)

(1,1) (2,2) (3,3) (4,4)

(2,4) (4,3) (3,1) (4,2)

(2,3) (3,3) (2,2) (3,2)

(1,1) (1,4) (4,1) (4,4)

that is as far as i have got at the moment but i cant seem to get past level 11 :(

any help for 5x5 grid appreciated :) thankyouu x

I couldn't solve the puzzles with the solutions provided above. However, I did figure out how to solve the puzzles on my own. Here are my answers for solving the various grids.

For level 16 the pattern presented will be the inverse of the starting pattern. Just use the below coordinates to flip all the tiles. From here on out most of the puzzles are similar to this format, where you will need to flip all the tiles before solving.
