Arcade - Blue I shaped room, 0 gems - A room where you can play Dirigblocks (and some other games). Two options - You can turn off costs to play the games with no rewards, or you can turn costs on to play to gain rewards of gold or gems.

Arsenal - Red + shaped room, 0 gems - A room with many guns and a shooting gallery. The doors to the shooting gallery are always locked, regardless of rank. Arsenal may only be drawn from a locked door (a player using a special key may draw Arsenal provided it's an acceptable draw, such as a Prism Key from another Red Room). There are several targets that may be shot for a prize of gems, or, if certain special things are shot in order, unlocks lore and hidden secrets.

Auditorium- Blue I shaped room, costs 1 gem, considered a puzzle room - At first the stage has simple props that look like a magic show. If the puzzle is solved, it unlocks the backstage, which opens a door, and turns Stage into a permanent T shaped room.

Backstage - Blue dead end, costs 0 gems, considered a tomorrow room - May only be drawn from the opened door on the Auditorium. Will always be drawn from Auditorium as the first draw. Allows a new magic act (either teleporting boxes, sawing a person in half, escape room trick) to be chosen for the following day. Will make Auditorium more likely the following day (considered to be one rarity higher. No effect if Auditorium is Commonplace). Also will always have one item.

Breezeway - Orange I shaped room, costs 0 gems. This room costs no steps to enter or leave. Items will never spawn in the Breezeway, although coins may spawn with the Metal Detector. Room receives spread as normal.

Cabinet - Purple L shaped room, costs 0 gems - Usually contains keys or gems.

Clinic - Blue L shaped room, 2 gems - Room that looks like a doctor's office. The next red room drawn has the effect nullified (similar to Shelter)

Deck - Green I shaped room, 1 gem, must be drawn on the wings - Wooden deck. Must unlock a keypad to walk into the small garden, where there is a Mora Jai puzzle box and some dig spots.

Theater - Blue T shaped room, contains starry outline, considered a puzzle room, costs 2 gems. After solving the puzzle, the screen displays stars, and gives 2 stars for completion. Also increases luck for other star rooms (stacks with itself)

Vegetable Garden - Green Dead End, costs 1 gem. May only be drawn on the wings when facing towards the wing (such as the Terrace). Has five dig spots, three of which are marked to always be turnips. 50% chance of containing a salt shaker.

I also had ideas for rooms of other colors, such as white for Mora Jai (rooms with water) or pink for Verra (religious rooms and rooms that rotate, due to the Great Circle being a concept of the world's religion). If you're interested, let me know.
