I can explain how the floor 100 I found the solution when I did this last level of the game. Hopefully at the previous level you are able to do and to finish well.
I already know the explanation for the level 100. First, look through the entire grid, we'll see that there are 4 yellow dots on the grid. Next, shift 6 sliding panels from each row to the right, you will see a numeral 0 there, looks something like a compass, and you'll see 7 arcs above that 0 point.
If you explore further floor 100, you'll find 2 more arcs at the top right corner of the grid, making a total of 9 arcs. I think this corresponds to the solar system, at least when it still had 9 planets.
Game 100 floors now complete, you can continue with other games that are not less interesting, or are curious about going back to the explanation of level 98-99?
