No Logic is a logic level where items are placed completely randomly, without placement rules. You are allowed to use many different glitches. Certain situations may be difficult to resolve, but unbeatable seeds are exceedingly rare.
In the ALTTPR Racing Ruleset, No Logic allows all glitches except (underworld) Exploration Glitch, Underworld Fake Flute, and arbitrary code execution. You are allowed to collect crystals from the wrong dungeon using crystal duping.
Frequently used glitches include:
- Overworld Glitches
- Underworld clips
- Door glitches
