The EBU Acol Daylong Tournament is the EBU sanctioned variation of the popular Acol Daylong Tournaments. It is 12 boards long, scored in Matchpoints, and you have up to 24 hours to play it. A new EBU Acol Daylong Tournament is available every day, from midnight to midnight GMT.

Each table consists of one human player, sitting South, and three robot players sitting in the other three seats. You are competing against every other human player sitting South, and playing with and against identical players.

Your partner and opponents are advanced robots, set to play the Acol system. The game awards EBU points and BBO Points if you do well.

What are Daylong Tournaments?

Daylongs are a type of robot tourney (one human player plus three robots at each table) where you get up to 24 hours to complete your game. You can register, play at your own pace, leave the table, then resume the game any time during the day without losing your results, from midnight to midnight GMT (UTC). You get a provisional result right after you finish playing, and the final results will be available the next day (after the tournament is completed), in a BBO mail.

Results

A provisional leaderboard is available right after you finish playing, and can be accessed while the game is in progress in the list of Completed tournaments. Your final results will be sent to your BBO Mailbox, or can be accessed in Recent Tournaments, in the History tab, after the game is completed.

Human Declares

The human player is switched into the North (Robot) seat whenever North is the declarer. The human player then declares the hand. When the hand is over, the human is switched back to their original seat.

Deal Pool

For every board in a Daylong tournament, BBO deals multiple instances. (Not everyone gets the same board 1, board 2, etc.) This is an anti cheating measure.

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. Reading these explanations carefully before you bid will help you avoid misunderstandings with your robot partner.
