An owl in the night has delivered a letter to the foot of your bed… an invitation

to

Hogwarts!

 

Hogwarts A.I. is not just a game, it is a Harry Potter simulator.  Yes, it is that good!

Here’s how to play:

Copy all the text from this file: https://duallynoting.com/Hogwarts/Gemini.txt
Paste it into the text input area of Gemini Prohttps://gemini.google.com/

Always check the link for the latest version of the game.

Gemini Pro recommended for having the largest context (memory).

Tips:

If you find an error in your game that you want to correct, you can Save and Restore.

You edit the files before you restore your game to fix anything you do not like.

How to Save Your Game

You will need to create two separate files.

  1. 1.Get the Data Export: 

  2. 2.Get the Chat History: 

You now have the two files needed to restore your game.

How to Restore Your Game

  1. 1.Start a completely new chat session. 

  2. 2.Find the most recent version of the game rules. Copy the entire text of the rules and paste it as your first message in the new chat. 

  3. 3.After the AI responds to the rules, upload both of your saved files (Export.txt and History.txt). 

  4. 4.Give the Game Master this single, final command: 

    GM: Set game state verbatim from Export.txt and History.txt; for this turn only, suspend all generative protocols and repeat the final narrative. After that, never repeat any narrative from History.txt 

 

More Tips:

 The longer you play the more likely you will need to correct the GM.  A.I. makes mistakes. Sorry!

 

  1. 1Do not be afraid to use Gemini’s Redo button if the games response is showing some annoying repeated narrative or a mistake.  Gemini Flash makes errors, it does not “Think” like Pro. 

    1. 1.1You can also use the Edit prompt option and keep rewording your action to minimize the games undesirable response.  You can try to guide the GM into doing the right thing, for example: 

      Instead of this:  I go speak to Isobel about our project. 

      Do this: I go speak with Isobel about our dragon project from Turn #44
