Quick and Dirty Dungeon Generation
Arrange some squares in a grid, assign them numbers that can correlate dice along the axis. How you proceed from there is up to you really as this is meant as a brainstorming tool. You can roll dice to decide where corridors might be, or perhaps roll 2 dice and see where they intersect for encounters, treasure, or anything really. You can also ignore the dice and go free form. Don't be afraid to have dead space in the dungeon or rooms that are inaccessible, or if you want just throw in a secret door. I made this on a index card so I could easily make a deck of these as different floors in the dungeon as well. I've also thought about using this as a vertical dungeon as well. Just an idea I'm throwing out into the ether.
