This time I will explain the clearance process of 100 doors (76-77).

Enter 76, close the back door is a cipher, enter the four password, we can open the door, there are four icons on the door, the left side of the door has a triangle equal to one, it is composed of a triangle. On the right, there is a pattern composed of two right angled triangles, which is equal to three. The description consists of three triangles. After looking at a row of icons on the door, you can see that there are clues on both sides of the door. The first icon on the door is composed of a triangle and two patterns on the right wall. Then go to this pattern and there are several triangles. The final answer is that it is composed of nine triangles. The first number is nine! The second icon on the door is a rectangle, which is a rectangle

It's not a triangle, so there's no triangle, and the second number is zero. The third icon on the door is a triangle, which is composed of a triangle, so the third number is one, and the fourth icon on the door is a prism. Count carefully, it is composed of two triangles, so the last number is two. The final password is 9012, enter the password, the back door will open, and then show the green arrow, click the green arrow will enter the next level.

After entering, we will see a large password device on the door. There is a large clock on the floor, but the center is not the hour hand and the second hand, but a symbol. This symbol can be regarded as a plus sign or a multiplier sign. Whether it is regarded as a plus sign or a multiplier sign depends on the angle and direction of your view. Then there should be a rotating arrow on the side of the clock to tell you which direction to start. The arrow goes from one to the other, so from the first point of view, it is one times five equals five, two plus six equals eight, three times Qi equals twenty-one, four plus eight equals twelve. All the numbers are used

, and then the password is 5.8.21.12. After inputting the password on the password device, the door will be opened to show the green arrow. Click to enter the next level.

OK, I'm going to play the game. I'll talk about the rest later.
