How to Play Quarto
The goal is to place 4 pieces in a row (horizontal, vertical, or diagonal) that share at least one attribute.
Shape: Square or Circle
Size: Large or Small
Color: Dark (walnut) or Light (maple)
Consistency: Solid or Hollow
The Twist: You do not choose which piece you play. You choose the piece your opponent must play, and they choose the piece you must play.
The Oracle
An advisor, not a boss — it is an option, and it gives you no advantage unless you press it. On your turn, 🔮 Oracle looks at every choice open to you: every empty square (columns A–D, rows 1–4) when you are placing the piece you hold, and every remaining piece when you are choosing what to hand over.
How it thinks: the shared minimax engine used across tedponderings.com. For each choice it looks ahead: what you would hand over next, every reply the opponent could make, your answers to those, and so on, assuming both sides play their best. When it can see all the way to the end of the game it says so exactly — a green Win in n, grey Draw or red Loss in n tag (turns from now). Earlier in the game it cannot see the end; it then shows an amber look-ahead score whose only ingredient is how many safe pieces (pieces that cannot complete a line) each side will have left to hand over, and the fine print says how far it looked.
The best choice is listed first with a plain-language reason. The computer player never uses the Oracle; it plays by its own code, which the Hint button shows.
