Play the 7♥ to start. On your turn play a 7 to open a suit, or the 6 / 8 next to a suit's exposed end. No legal card? You pass. Empty your hand first to win.
Badam Satti (Sevens) — how it works
Players: You (South) + 3 AI (West, North, East). Turns go clockwise.
Deal: All 52 cards, 13 each. Rank order A · 2 · 3 · 4 · 5 · 6 · 7 · 8 · 9 · 10 · J · Q · K.
Start: Whoever holds the 7♥ (Badam Satti) must play it as the very first card, opening the hearts row.
Your turn — you must play if you can: either lay down a 7 to open a new suit, or add the card immediately below (6, 5, 4… down to Ace) or above (8, 9, 10… up to King) the exposed end of a suit already begun.
No legal card? You pass — the turn moves on.
Winning: The first player to get rid of every card wins. The rest are ranked by how few cards they have left.
