Turn device upside down, note the level number is 81. The six’s have now become nines, darken 9 x 9 which equals 81, the press the equals sign.

Tip your phone upside down so the 6's become 9's, then darken 9 x 9 then = sign

9×9=81

Turn your device upside down and click 9 * 9 =.

This is a motion sensor stage. The goal is to reach 81. The lines above what look like 6′s are actually telling you that they are 9′s. 9 times 9 is 81 so with your device upside down push 9 times 9 and the door will open.

Ive tried everything 9×9 upside and notnive tried clicking equals sigh after it it still hasnt worked…

I’ve tried everything as well exactly as y’all say to do it it doesn’t work

There are 4 9′s and two x signs. Does it matter what combo you use? I’ve tried them all and still can’t get it open!

hold your phone verticle when you do it…no angle

I found it out! You have too press 9 then 9 then X not 9 x 9 make sure it’s on the top row only

also tried every 9X 9 combo and doesn’t work

It worked for me.have you cleaned your screen in a while?

Anyone over the age of 9 who can’t do this is quite slow. Simply put:

The 6s have lines above it which indicate to ANYONE that the bottom of the number is the line, which means you have to turn your phone UPSIDE DOWN.

The floor is 81 and you have nothing but 9s and + or x…. Everyone over the age of 9, without special needs, SHOULD know that 9×9 = 81.

This level is so hard I tried everything. I don’t understand it.
