Love poker nights but sick of counting chips? Chip Duel replaces the chip box. Deal real cards as usual — the phone keeps score. ONE PHONE ON THE TABLE Lay the phone flat in the middle. Each player gets a seat around the screen — seats opposite you appear upside-down so they read perfectly from the other side of the table. Big Fold, Call and Raise buttons turn to face whoever's turn it is. EVERY PHONE AT THE TABLE Or host an online room with a four-letter code. Everyone joins from their own phone, picks their seat, and sees their own chips front and centre. Bets, raises and wins appear on every phone within a second — when you win a pot, the chips visibly sweep to you on your screen and drain away on theirs. A PROPER POKER ENGINE • 2 to 6 players, with automatic blinds and dealer rotation • Full betting rules: checks, calls, min-raise enforcement, half-pot / pot / all-in shortcuts • Correct side pots when several players go all-in for different amounts • Split pots for ties, player elimination, and a champion at the end • Undo any action MADE FOR THE KITCHEN TABLE • One-phone mode works completely offline — planes, campsites, power cuts • No accounts, no adverts, no tracking, and nothing to buy • Full VoiceOver support: every bet, turn and winner is announced Chip Duel counts chips like a scorepad. It contains no cards, no dealing and no real-money play.
