Create a game, send one link. The first four people who open it play on a 14×14 cross-shaped board — everyone after that watches live. No accounts, nothing to install, free. Two languages, dark mode, works on phones

Zagraj w szachy we czterech na planszy 14×14. Tworzysz grę, wysyłasz jeden link — pierwsze cztery osoby grają, reszta ogląda na żywo. Za darmo, bez rejestracji.

Stwórz grę i wyślij link. Pierwsze cztery osoby, które go otworzą, grają na planszy 14×14 — każda kolejna ogląda partię na żywo. Każda gra ma własny adres. Możesz prowadzić dowolnie wiele partii równolegle. Miejsca zapełniają się w kolejności ruchów: czerwony, niebieski, zielony, żółty. Gra rusza przy czwartym graczu. Ten sam link, plansza na żywo i historia ruchów. Zwykłe zasady szachów na planszy w kształcie krzyża. Wszyscy czterej gracze na jednym ekranie. Imiona są opcjonalne. Wpisz swoje imię, kliknij „Stwórz grę" i wyślij otrzymany link trzem osobom. Pierwsze cztery osoby, które go otworzą, zajmują miejsca przy planszy — gra rusza automatycznie przy czwartym graczu. Nie.
