The Yes or No spread is a single Rune spread similar to Odins Rune. The difference being that the Yes or No spread is used to obtain either a "Yes" answer or a "No" answer concerning the question asked, or the matter being considered. The actual interpretation of the Rune is ignored when using this spread, although you are welcome to wave your mouse over the "Yes or No" Rune and read it's interpretation if you like.

After the "Yes or No" Rune is cast, the Rune will appear and your answer will be revealed directly below the Rune itself.

"Yes" and "No" answers are determined by whether the Rune (if it happens to be a Rune that can be read either "Upright" or "Reversed") is  cast Upright,  or Reversed. If the Rune is Upright, the answer will be Yes. If the Rune is Reversed, the answer will be No. If the Rune cast is not a Rune that can be read as either Upright or Reversed (Non-Reversible),  Runes, the Ancient Oracle will prompt you to "Cast Again".
