A Very Simple Method for Random Dungeon Generation

I have decided that MoBaD (Maze of Blood and Death) - my homage to DeathMaze and Citadel of Blood - will not use a pre-generated map. I long ago decided against chits. Instead, MoBaD will have the player(s) randomly generate their dungeon layout on-the-fly in a manner similar to PocketDungeon. There will be a "mapping-grid". You'll start in a bottom corner and "build" the dungeon horizontally until you run out of room. Then you'll move up the grid. It's sort of like laying tetris bricks.

You build the rooms with "Room Blocks" - a column of 4 squares. You roll 1d6 to determine how many "room-blocks" you'll use to build the room. You have to place your room-blocks in-line with your current room. If you run out of room for the number of room-blocks you rolled, use the left-overs to build the next room up the grid.

I rolled 3 for room one. I rolled 5 for room 2. I rolled 1 for room three. I rolled 6 for room four. I rolled 2 for room 5. I rolled 2 again for room six but there wasn't enough space for a 2-block room. I made room 7 with the left-over block. Skipping ahead to room 12, I rolled 3. Again, not enough room for 3 blocks. Room 12 uses 2 of the 3 blocks I rolled. Room 13 is formed with the left-over block.

East/West door will always exist within the boundaries of the mapping-grid. Sometimes, there may be a north door. This is determined by rolls for "room features". There is always a north door where there is a gap in the black lines.
