You get a lamp at the start. The lamp is used to open paths. At the end of every path you get another lamp so you'll never be stuck in a dead end.

The yellow gauge on the left increases as you progress through the labyrinth, and it also increases everytime you use your master spells.

Your goal is to simply progress to the next floor. You know you're in the right direction when you fight the giant ghost boss.

It's much easier to just follow the maps from this https://www.reddit.com/r/FGOGuide/comments/b6255x/quick_tokugawa_kaiten_labyrinth_event_guide/

Every time you fight a giant ghost your master spell gets an upgrade. All of the upgrades are listed under the "Tokugawa Crest Skills" on this wiki page.

At the end of chapter 8 when you reach the 6th floor, a bunch of extra paths gets added on floor 1-5. These are the "mystery spots". Some of these gives the Hanafuda cards (the card with the red flower on it) that you could use to reduce the yellow gauge, which will weaken the final boss ala CCC KP. There are 25 cards in total, each reducing the gauge by 4%.

I think that covers just about everything but feel free to ask again if I missed something.
