Level 36: Move the ball to the right. This will reveal another arrow. Trace two imaginary line from each arrow and note the where they intersect. Tap at that imaginary place and a little circle will pop out and the bar above the door will turn green. Now you can open the door.
Level 37: Tap the globe to lift up the globe. While it still up grab the black flashlight. Use this flashlight and on the arrows above the door. You will see several continents note this and which hemisphere there on. Then tap the appropriate buttons. If you don’t want to figure that out just tap left, right, right, left, right. Now all you have to do is open the door.
Level 38: Use you light onto the top corners. You will see ball on the left, and stone on the right. So tilt it all the way to the right until the stone moves past the red line. Then gently tilt to the left so the balls move over there but not the stone. Finally you can open the door.
Level 39: Tap the blocks on the wall in order from biggest to smallest based on the amount of color is on the door. So it would go red, green, yellow, blue, to get the door open.
Level 40: Slide the door to the right. Then slide the door up. Finally slide it to the left and it will be open for you
