Preferans

Preferans (Преферанс) is a classic three-player trick-taking card game,
much loved across Russia, Ukraine, the Balkans, Greece, and beyond. It is
related to Bridge and the older European game Vist (Whist), but stands on
its own thanks to its distinctive bidding ladder, the Miser contract, and
the cooperative-defense logic of "Whist" play.

This app lets you play Preferans against two computer opponents on your
phone or tablet, anywhere, no internet needed.
