Shark Bridge questions
What is Shark Bridge?
Shark Bridge is online contract bridge. You can play robots or friends in the app, join ACBL-sanctioned games at Online Bridge Club, or teach a class in the Teacher's Console.
How do I log in to Shark Bridge?
Go to arena.sharkbridge.club and sign in with your email, or with Google, Apple, Microsoft or MyACBL. If you are new, you can register on the same screen.
Is Shark Bridge free?
You can start free. Every Shark account comes with 5 free SB Credits, enough for two 12-board games or one 18-board game, and they never expire. ACBL members with fewer than 5 lifetime Masterpoints play any 12-board game free until they reach 5. Once the free credits are used, a 12-board game costs 2.25 SB Credits. The app is free to install and try, and a free 12-board social game without Masterpoints runs every day. A VIP subscription unlocks full access to the app but does not cover Masterpoint games.
How do I use my 5 free SB Credits?
They are already in your account, so there is no code to enter. Sign in at arena.sharkbridge.club, choose a 12-board or 18-board game and play.
Do players with under 5 Masterpoints pay?
Not for 12-board games. ACBL members with fewer than 5 lifetime Masterpoints play any 12-board game free until they reach 5, and they keep their 5 free SB Credits for other games.
What is the Game-Day Challenge?
It is a month-long competition played with robots. Each day your results set your place on the Daily Leaderboard, where a qualifying finish earns extra Masterpoints. Over the month you collect badges that pay free SB Credits.
Do the games award ACBL Masterpoints?
Yes. Game Day, Insta-Game and Play & Learn all award ACBL Masterpoints.
Which devices does Shark Bridge run on?
iPad, iPhone, Mac and Windows 11.
Can I play bridge against robots?
Yes. Three robots take the other seats, so you can play at any hour without waiting for a table.
Is there a tool for bridge teachers?
Yes, the Teacher's Console. You can teach up to 500 students at a time with live video and voice. It runs on a Windows computer, or on a Mac with a Windows virtual machine, and students join from a web browser. Teachers ask Shark Bridge for an account, and not every request is accepted.

Play bridge online with robots
You don't need a partner or a table to start. Three robots sit down with you, so you can play solo bridge against robots whenever you have a spare hour. They know the common bidding systems and conventions. New players start on SAYC, and you confirm or change your system before you join a game. Our robot convention cards include 2/1 Game Force.
The robot behind the game
Our bridge game software started with the robot. John Norris, a professional player and coder from Denmark, began work on the idea in 1997. Shark went on to win the World Computer-Bridge Championship in 2011 and 2014.
ACBL Masterpoint games online
To compete, join our ACBL Masterpoint games. They are ACBL sanctioned, and the American Contract Bridge League lists Shark Bridge among its online Masterpoint games. The Game-Day Challenge runs all month, played with robots. Insta-Game is 12 boards at any time, with feedback after every board. Play & Learn is a weekly game and lesson, and the teacher reviews the hands after each round. All of them award Masterpoints. Every Shark account comes with 5 free SB Credits, enough for two 12-board games or one 18-board game, and ACBL members with fewer than 5 lifetime Masterpoints play 12-board games free.
The Shark Bridge app
The Shark Bridge app runs on iPad, iPhone, Mac and Windows 11, and it is free to install and try. You can play the bridge game with friends or robots and open the hands your teacher shares. A VIP subscription gives you full access across your devices, but it does not cover ACBL Masterpoint games.
Teach bridge online
The Teacher's Console lets you teach bridge online or in a classroom. Teachers run it on a Windows computer, or on a Mac with a Windows virtual machine. Students join from a web browser, and a class takes 1 to 500 students at a time, with video and voice. You seat students at tables, deal prepared hands and fill empty seats with robots. Shark is also the technology partner of BridgeWhiz, the youth program for grades 4 to 12 affiliated with the ACBL Educational Foundation. Need lessons? Find a bridge teacher.
About The Shark Bridge Company

Co-founder Milen Milkovski has played bridge since age 12, has built bridge games for mobile devices since 2008, and started the Shark Bridge project in 2014. You can read our story, or sit down and play a few hands.
