How it plays
Quarto reverses the usual placement decision: your opponent chooses the piece you must put on the board. After placing it in an empty space, you choose their next piece. Every piece has four visible attributes, including height and color, and neither player owns one color or type.
A winning row, column, or diagonal contains four pieces sharing at least one attribute. They need not look identical overall. Because both players place pieces into the same patterns, the piece you hand over can complete an arrangement you helped build. You must notice and announce the winning line.
Decisions you’ll make
Before giving away a piece, check every nearly completed line for each attribute. A short hollow piece may be safe for color but dangerous for height.
Choose a placement with the next handoff in mind. Filling a square can remove a threat while creating another line that restricts which pieces are safe to offer.
Learning the game
Light: the turn sequence is short, but demonstrate all four attributes and the requirement to call Quarto.
