This time, I will explain the 18-19 level of the house of 100 doors [Christmas version], and pass the process.
After entering, there are two red shutters on both sides of the door. There are seven small lights distributed around the door. When you click them, they will light up. There are a pile of gift boxes in the middle of the floor. There are two small Christmas trees on both sides of the gift box. After many times of thinking, the method is to click on the small lights on the four sides of the door according to the number of flashing lights. The order of flashing lights is [we mark the number 126.96.36.199.5.6.7 on the small lights from left to right from bottom to top]. The first time we click on two, the other small lights will flash, and then click on 213 in the order of flashing. After clicking, the other small lights will flash, and click in the order of small lights flashing, that is 213654. After clicking, the other small lights will flash, click one by one according to the order of small lights flashing, and the number is 21365456312. After clicking, the other small lights will flash, and click one by one according to the order of small lights flashing, and the number is 2136545631271741, and then the door will open Out of the green arrow, click the green arrow, we successfully entered the next level. Successful access to the back door on both sides of a tray on the wall, you click on the left, the left will appear a Christmas tree, the top of the tree with an arrow sign, the direction of the arrow is left down, you click on the right, the right will appear a Christmas tree, the top of the tree with an arrow sign, the direction of the arrow is right up. The door is divided into 12 squares, each of which has a different picture. Items on the ground are ignored because I click on them without response or prompt. So the hint is the two Christmas balls with arrow marks inside. Mark the 12 squares from left to right and from top to bottom with numbers 1-12. First, we click 264, then 8.12, 10, and then 10.9.8.5.3.1 [the order of clicking is according to the arrangement of lights on the Christmas tree]. After that, the door opens and we click the green button to enter the next level.
