So here is an idea I had for a forum game…
The person making the room will be the ‘Room Master’
The Room Master will need to make a list of things that are initially visible in the room.
Players can reply asking to look closer at or perform some type of action on any single item from the list of items that will be found in the escape room.
When things are revealed, that should be noted by other players in that they may ask or say what they can/will do with said newly found items.
Anyone playing or replying will be in the room and helping (whoever) to escape or find a way out.
When players ask to look closer at, or perform whichever action on said things/items, the Room Master will reply with what that resulted in, or will verify that the answer to the question the item presents is correct. Like if clues point towards a series of numbers, the RM can verify if they’re relevant or not, or specify that those numbers are used somewhere with something else when asked.
Players may discuss amongst themselves what to do with any clues found. Or make note of any sequence of numbers or items they come across to use on anything later. Such as if you find what could be a combination, but no locks have been found yet. Or a key, but not the lock it goes to… (again) yet.
To make a room: I advise sketching it out on paper or in an art program. Make it like a tournament bracket. Have the door at the right, have that split to the left to 2 items, have those split to 2 or however many items and how they’re obtained, etc. Up until you have your list of items that can be seen in the room.
I’d also suggest going into your Profile, do like you’d do if you were going to send a message, but make it to yourself. Using the room item list you made from paper or art program, list items found from other items
A Fridge
You’ll copy the ‘Fridge’ item into your ‘Escpae Room’ post, but refer to the self sent PM as to what’s inside the fridge once a player asks to look inside the fridge.
- inside the fridge you find a carrot
Items of importance can be underlined. Try to use an emoji if one exists for the item you’re wanting to use for a clue or prop.
Player: Can I look inside the pumping?
RM: You found a
So then a candle would come into play as part of solving the escape room.
Once you have every aspect of the escape room worked out – then copy everything from that 1st Self PM post, paste it as a reply to the same Self PM, but delete all subsequent items/props/clues since those will be revealed later after successful player guesses and/or requests for actions.
At some point, the RM may have to give hints if players are way off, or missing something that players might not have looked closely enough at. 
At this point, I can’t think of anything else. The rules might need to be worked on or refined. I apologize if anything is unclear or hard to understand.
So lets see how this goes, and I hope everyone has fun! 
When this first room is escaped from - I’ll post what I made in the ‘Self PM’ to help illustrate how it’s all broken down if anyone wants to use that as an idea of how to make an Escape Room themselves.

Tomorrow I will be trying “0000”.
