What is the Yes or No Tarot?
Yes or no tarot is the oldest practical use of a deck, and the one most likely to be done badly. Plenty of sites just flip a coin and show you a picture. This one shows its working.
Each of the 78 cards in our deck carries a traditional lean: yes, no or maybe, based on its actual meaning. The Sun leans yes. The Ten of Swords leans no. The High Priestess leans maybe, because her whole message is that you do not have the full picture yet. On top of that lean the reading scores the way the card landed (upright or reversed), its suit, and its number or court rank, each with a reason you can read.
You also get a confidence score out of 100, so a weak yes and a strong yes do not look the same, plus traditional timing from the suit, and a plain section on what would change the answer. Because no honest tarot answer is fixed: it describes where things stand today.
How it works
The card is drawn from a seeded Fisher-Yates shuffle of all 78 cards, with a one in three chance of a reversal, and you choose which of 24 face-down cards to turn. Nothing about the verdict is random after that point.
Scoring: the card own lean is worth plus 2 for yes, 0 for maybe and minus 2 for no. Upright adds 1, reversed subtracts 1.5. Suits add Wands plus 1, Cups plus 0.5, Pentacles plus 0.5 and Swords minus 1. Numbers add their own weight, so Aces and Sixes help while Fives and Nines drag. A Major Arcana card adds no points but multiplies the whole subtotal by 1.3, because those cards describe bigger forces. Your strict or gentle setting then stretches or squeezes the score.
Bands: plus 3.4 and above is Yes, plus 1.2 to 3.4 is Leaning yes, minus 1.2 to plus 1.2 is Not yet clear, minus 3.4 to minus 1.2 is Leaning no, and below minus 3.4 is No. Confidence is the distance from zero divided by 4.6 and capped at 100. Every one of those numbers appears in your report.
How it connects to your star sign
The suit of your card sets the traditional timing, and the suit maps to an element and so to three star signs: Wands to the Fire signs, Cups to Water, Swords to Air and Pentacles to Earth. Numbered Minor cards narrow it further to one decan, a third of a single sign, which some readers read as an actual season to watch.
