Bridge Co

German Bridge isn't about winning the most rounds — it's about predicting exactly how many you'll win, then controlling the game to make it come true.

Coming soon to the App Store

How it plays

Bid exactly

Before each game you predict precisely how many rounds you'll take. Bids are public. Win more than you said and you lose — overshooting is as costly as falling short.

Squared scoring

Hit your bid and score 10 + bid². A bid of 6 is worth 46; a bid of 2 is worth 14. Big calls pay enormously and punish you just as hard.

Tables with friends

Private online tables for up to seven players, with a code to share. Empty seats fill with bots, and a dropped player's seat is held before one takes over.

Ranked seasons

A monthly rating ladder with a global leaderboard, or play solo against bots from beginner to expert. Every match is logged with a full score timeline.

Screens

A round in play: four players around the table with their bids, and cards played into the centre. — A round in play

End-of-match results: final standings, a cumulative score timeline and a game-by-game breakdown. — Final standings

Privacy

Full policy

No accounts, no tracking, no ads. Bridge Co never asks for your email, your contacts, your location or your photos. It contains no advertising SDK and no analytics SDK, so it never shows you an ad and never presents the "allow tracking" prompt — there is nothing in it to track you with.

What it does keep is the minimum a multiplayer game needs to work: a random identifier generated on your device, the display name you choose, and your game results — so your rank, coins and match history are still there next time you open it. Your name is visible to other players at the table and on the leaderboard; nothing else is shown to anyone.

The full privacy policy lists every field, why it exists and where it is stored, and the terms cover fair play and the in-game coins.

The rules, briefly

A match is a sequence of games with a changing hand size. Each game, a card is turned over to set trump, everyone bids the number of rounds they expect to take, and play goes clockwise — follow the led suit if you can, highest card of that suit wins unless someone plays trump.

The dealer bids last and may not choose the number that would make the bids add up to the rounds available, which guarantees at least one player misses. That single restriction is what makes the game a knife fight rather than an arithmetic exercise.

The app teaches all of it in an interactive tutorial on first launch — five hands-on puzzles rather than a wall of text.
