Roc
Grandma's card table, rebuilt for your phone.
Roc is Rook reborn: bid bold, call your partner's bluff, and drop a trump at exactly the wrong moment for everybody else at the table.
Play solo against AI that runs the whole range from kindly aunt to the cousin who counts every card and never lets you forget it, or go online against real people in real time. And every regional house rule your family used to argue about at Thanksgiving is in there. Pick your variant and play it the way you grew up swearing was the only correct way.
The rules are the reason this exists. Rook has been played slightly wrong in slightly different ways in a thousand kitchens for a hundred years, and almost every digital version picks one ruleset and calls the rest incorrect. This one doesn't.
Playable in a browser now. Still unfinished, still worth breaking.
