Hello Codeforces!↵
↵
Are you tired of only doing virtual contests? Want a more fun way to compete with friends, alone or on a team? Try Bingo-CP.↵
↵
### What is Bingo-CP?↵
↵
Bingo-CP is a free web app that turns Codeforces practice into a quick social game. Problems are placed on an n×n bingo board. Teams of 1–4 players compete at the same time. The first team to complete any row, column, or diagonal wins.↵

↵
### How to play↵
↵
**1.** Click "Create Match" as in the picture.↵
↵
**2.** Choose grid size (3×3 to 6×6), start time, duration, rating range, and mode.↵
↵
**3.** Add team members by Codeforces handle (1–4 each).↵
↵
**4.** Start the match. All teams solve at once. The first accepted submission claims the square for the team.↵
↵
**5.** First team to complete a row, column, or diagonal wins.↵
↵
Solves are detected automatically from Codeforces submissions, so no one needs to claim squares manually.↵
↵
### Match options↵
↵
Start time and duration.↵
↵
Rating range for problem selection.↵
↵
Mode: Classic (fixed board) or Replace.↵
↵
Replace mode: when a square is solved it is replaced by a new problem that is tougher. The replacement’s rating is the solved problem’s rating plus the Replace increment. ↵
↵
Example: a solved 1400 with increment 100 will be replaced by a 1500 problem. Replace mode keeps the board getting harder as the match goes on and encourages different team strategies.↵
↵
Grid size: 3×3 to 6×6.↵
↵
Team handles: enter Codeforces handles for each team.↵
↵
### Modes↵
↵
#### ICPC mode↵
↵
This is the main mode right now. You can play Classic or Replace.↵
↵
#### IOI mode↵
↵
Planned, but currently disabled because of API issues. I’m working on a fix.↵

**UPD:** We recently experienced a database issue that caused some errors on the website. The problem has been resolved. Sorry for the inconvenience.
