About ACBL Daylong Games

ACBL daylong tournaments offer a flexible way to play bridge online, and the opportunity to win ACBL masterpoints. You can start a game, pause anytime, and resume it later within the same day, without losing your progress. The final results are delivered to you the next day via BBO mail and listed under Completed Tournaments.

Game specifics:

• Choose between 12 or 18 boards.
• Matchpoints or IMPs scoring options available.
• Once you start, complete your game by 5am US Eastern Time the next day.
• The game is stratified, allowing for a level playing field for players of all experience levels.
• Top finishers earn ACBL masterpoints and BBO points.

Daylong Format Highlights:

• You'll be seated South, with three advanced robot players filling the other seats.
• Provisional results are available during play. Your final results will be sent to your BBO Mailbox, or under Recent Tournaments, in the History tab, after completion.
• You're typically dealt the "best hand" at the table, making the game more engaging and fun.
• If your robot partner is the declarer, you'll take over to play the hand, switching back afterward.
• Each daylong game uses multiple "deal pools", to prevent cheating.

About the Robots

The robots used on BBO are called GIB (Ginsberg's Intelligent Bridgeplayer). You can find out more about GIB's bidding system by clicking here.

The robots used in BBO play a relatively simple and natural 2/1 bidding system. You can find out the meaning of any bid by clicking on that bid as it appears in the bidding diagram. Furthermore,when it is your turn to bid, moving your mouse over the buttons for the various possible bids will cause an explanation of the bid you are considering (as your robot partner will understand it) to be displayed. These explanations can be somewhat cryptic, but reading them carefully before you bid will help you to avoid misunderstandings with your robot partner.
