This is just to give you guys some idea of what they read in the invitation. I can't draw well and I can't put images in here so I just translated the text I pictured here. I also didn't put much effort into the descriptions of the layer since I couldn't find much on it myself. If you wanna send a link with more stuff about it I could add a bit more, but I don't think there would be much information there to begin with.

The Nazarick Games
Octuber 31, Shibuya
You are cordially invited to participate in a once-in-a-lifetime event. I, Ainz Ooal Gown, grant you the possibility of achieving your dreams. Will you accept it?
The rules are simple, meet me and the other contestants at Shibuya on October 31 of this year, pay the entry fee, and enter the game.
The goal is to reach me in the deepest layer of my Domain. You have 24 hours to do so.
Once you get to me I will use all of the cursed energy I have plus whatever I can gather during the preparation for the event and during the event to perform a massive cursed technique.
This will allow you to turn a wish into reality. The wish has minor limitations, but I'll work alongside you to find a compromise should it be impossible to grant.
The price is fixed at one Sukuna finger per group of up to three members meaning that we should have 20 to 60 contestants at any time, but that's not a guarantee so be sure to get one as soon as possible.
I will have a player of my own playing the game on my behalf. He'll not be allowed to beat the game and will instead try to hinder you and your team.
By signing up you are agreeing to forfeit your soul and all the cursed energy you possess to me.

Rules
The event will take place on October 31, 23:59:59, and will last until November 1, 23:59:59. During this time I, Ainz Ooal Gown, will allocate all of my cursed energy to maintain my Domain over all of the 9 locations.
You must enter the game through the Domain in Shibuya.
You are allowed to enter at any time during the game.
You are allowed to leave the Domain, should you do so you forfeit your right to participate.
Should you leave with the invitation in hand it will be teleported to anyone from your group who is still inside. If there is no one this invitation will be canceled.
Players are allowed to team up however they want, but team swaps are prohibited.
Whoever holds this invitation after reaching me will be recognized as the leader and given the right to choose the reward.
The invitation you used to sign up for the game is the only one that will give you the ability to choose the reward. If you or anyone from your team don't have it when you reach me you'll be teleported to the outside of the room.
Once you enter the game, the invitation will be used to determine the teams and randomly teleport you and your group to a room inside the first layer. The team leader has to enter first followed immediately by the other members to guarantee the same spawn.
On each layer, there is only one room with an opening to the next one, which will be referred to as the door.
While there is only one door in each layer, there are many different paths to reach it.
There is a guardian on each layer.
The door will only open after the guardian is defeated and will remain open for the rest of the game.
Once a player passes through the door they and their team will be teleported to a random room in the next layer.
Should you attempt to return to a previous layer you'll be given the option to leave the Domain. Retreating a previous layer is prohibited.
There will be non-sorcerers (civilians) trapped on each layer. They will give you a bonus should you take the time to save them.
To save a civilian you must either take them back to begging of the layer or to the door. Once they cross to another layer or the outside, they will leave the Domain.
Third Page
Your bonus will show up on the 5th page of this invitation alongside mission briefings. The page will be available only during the game.
Missions are special assignments given by me to spice up the game. They could include anything and are completely optional.
You'll see what the reward is when deciding whether you accept it or not.
You are allowed to cancel a mission at any point.
Any special items will be granted via teleportation at the time you are eligible to claim them.
Killing another sorcerer will net you benefits. Read the 6th page of this invitation for more information. (6th page is not available until you kill a jujutsu sorcerer.)
Should a jujutsu sorcerer be killed they can be replaced by someone else, just be sure to have all the potential candidates for your team sign the invitation before entering the game.
You are allowed to teleport inside a layer, but the destination will be randomized.
You are allowed to break doors, walls, or anything else, but they will be rebuilt within a few minutes.
If any more rules are added they will be added to this section with the approval of Tengen.
Limitations
All cursed techniques and cursed tools are allowed, but any Domains will have their shells cracked from the outside.
I can not cancel a mission unless there is no team currently attempting it.
I can not exit the final room for the duration of the game.
I can't interact with anyone except through a mission during the game.
All of the cursed spirits will be given orders when the Domain is created and thus I will have no direct control during the game.
For the duration of the game, my cursed energy will be limited to the equivalent of a fourth-grade cursed spirit.
Should I die during the game Tengen will assume the responsibility for maintaining the game. If he fails to do so, all the cursed energy used to create the Domain will turn into a bomb.
Should I die during the game my role will be passed to Yuki Tsukumo who will be under the same limitations as I am.
Yuki Tsukumo will not be able to alter anything about the structure or the inner working of the Domain. Only superficial aspects of it.
Yuki Tsukumo and Tengen can not be players.
I will issue no more than 20 invitations, of these invitations I shall hand out only 2 invitations directly. The rest will be given for distribution by a third party.

Domain
There are 9 layers with different environments and curses spread around Japan. Their scale is around 400 meters each.
Layers 1 to 3: Catacombs
It is a claustrophobic map illuminated by torches, the design is a maze with great focus placed on confusing the player.
The player will wander corridor after corridor made of cobblestone and metal doors while they fight undead creatures.
Layer 4: Lake
The most straightforward layer. It's an open area where the player can easily identify the door and the guardian.
Passage over the lake can only be done safely with a special boat procured on-site.
Layer 5: Glacier
A frozen hell where the player will have to traverse an open area while fighting multiple cursed spirits.
Layer 6: Jungle
What's there to say? It's a closed humid forest. Finding the door will not be hard.
Layer 7: Blazing Temple
A temple surrounded by a lava lake. The player will suffer from extreme heat while looking for the door inside the temple.
Layer 8: Wilderness
I'll leave this one as a surprise for you.
Layer 9: Royal
The final layer. It is a castle structure with beautiful ornaments all around. The guardian will be guarding my room.
