[Free] Doors

Level 26 is the one with the different colors on the wheels that turn on both sides of the door and the colored pattern on the door itself
 
Door 31 is the one where you tilt the phone to open the door but the spikes go up when the door gets to a certain point
 
You need to make a blue triangle in the middle so the red dots are on the outside if you look at the dots before clicking them it shows you the shape :)
 
You just hold the button and the tlred dots above the doors turn green. Doesn't matter how many times you press the button. Just hold it.
 
cAn someone please give me the code for 18, no matter how much I tilt my phone no numbers come. Thank you
