Red-haired beauty While lamenting the sacrificial behavior of teammates, she patrolled the room.
But Yang Xu fell into contemplation upon seeing the familiar room layout. Like the Cat cafe and medical warehouse from before, this place also had only three doors. Could it be that she had encountered a boundary?
So, does that mean that if you go in the opposite direction of the other two doors, you will end up in a room with only two doors?
Based on your direction and the direction of the "Cat cafe" and "medical warehouse" from before, it's very likely that behind this door is a vertex.
In order to confirm his guess, Yang Xu turned and chose a door to enter, and the Red-haired beauty behind him didn't have time to stop him. (PS: After someone dies, they can choose a door to enter.)
Sure enough, there are only two doors here.
And in the center of the room, the golden trench is still floating the number 4, so now all the guesses are correct.
As Red-haired beauty said, this game room is a construction of Sudoku, a large 9×9 square that can also be divided into 9 smaller 3×3 squares. The goal is to ensure that no repeated numbers appear horizontally, vertically, or within each 3×3 square.
And now I'm in one of the four corners of the 9x9 grid, so it seems much clearer. Starting from this corner's 3x3 section, and adding the known information to analyze (from previous conversations with people), using X to represent unknown numbers, the known information for the first four rows is as follows.
4, X, X (Cat cafe), X (medical warehouse), X, X, X, X, X
X, 6, 1 (supermarket), 2 (internet cafe), X (swimming pool), 4, X, 8, X
X, X, X (classroom), 8, X, X, X, X
X, X, 8 (hotel), X, X, X, X, X
"What are you thinking? You look so serious."
"Red-haired beauty"s voice came from behind Yang Xu, she stood not far behind Yang Xu, "I called you several times, you didn't respond, what are you doing?"
Yang Xu turned to look at her, took out the paper and pen in the room, and started writing, making a mark to aid understanding.
As Yang Xu's marks increased, Red-haired beauty began to understand slowly.
It seems like this is a good starting point.
After finishing the marking, the two of them returned to the room with the number 6wooden blocks and chose the room directly below it. But as soon as they entered, they were stunned for a moment, but quickly regained their composure.
Red-haired beauty looked at the floating 8-shaped groove in the center of the room, feeling slightly annoyed: "So the man told us a lie. If there's an 8 here, then there can't be an 8 over there. It looks like we'll have to seek revenge when the time comes." After speaking, she looked indignantly at Yang Xu.
Yang Xu nodded in response, saying, "Of course."
Now the marked X and 8 have been exchanged. After Yang Xu finishes modifying, he is ready to continue to the room on the left to take a look.
Red-haired beauty closely follows Yang Xu and also goes to the room to the left of the number 8.
This room is a playroom, with a little girl and a boy inside, contemplating where to place something in the recess in front of them.
22 (little girl): "Is someone coming?"
68 (male): "Hello, let's think together about how to place this number."
Yang Xu willingly agreed: "Sure."
"2, 3, 5, 7, 9, you can pick any one."
The little girl asked in confusion, "Why are you saying this?"
"I don't want to say more," Yang Xu handed over the marked paper.
The boy took it and suddenly realized, "So that's how it is." He handed back the paper and looked at Yang Xu, "It looks like you two have also entered many rooms."
Red-haired beautyWith arms crossed, she casually asked, "So, which room did you start from?"
The little girl replied, "We came up from the room below."
