Triad the solitaire

Clear the board in groups of three. Every deal is solvable — but the order you clear it in decides whether you strand yourself.

No triads collected yet.

    How to play

    Every card has four attributes: how many shapes it shows, which shape, how it's shaded, and what colour it is. Each attribute has three possible values.

    Pick three cards. They form a valid triad only if, for every attribute separately, the three cards are either all the same or all different — never exactly two matching and one different.

    • Tap three cards to try them as a triad.
    • A correct triad clears; a wrong one flashes red and clears your selection.
    • Hint always suggests a triad that keeps the rest of the board solvable — it will never strand you.
    • If no triads remain and cards are still on the board, you're stuck — undo and try a different order.
    • Undone triads stay in the tray below the board, dimmed. Click any of them to jump back and forth through your moves.
