Hi Codeforces,

I have tried making a web app — CfLockout that allows you to create practice contests of Codeforces problems. You can select different ratings of the problems and only the problems which are unsolved by all the participants appear in the contest.

Only the user who solves the problems first is awarded the score, so be quick to solve the problems ;)

Website link — https://cflockout.live Github link — https://github.com/prayutsu/cflockout

Note — Email verification mails may lend in your spam folder, mark them not phishing to be able to click the verification links.

Do star the repository if you like the project.

Update #1: The maximum number of problems allowed has been increased to 10 and the maximum difficulty of the problems is now 3500.

I haven't tried it yet but it looks pretty good!

I think the limit for problems per contest is too small, could you please make it larger?

Also, why are there limits for difficulty chosen?

Thanks!

    Can you suggest any number?

    I'll increase the maximum difficulty of the problems to 3500, and I am thinking of limiting the max number of problems to 10.

This looks amazing, and I will be using this a lot! Thank you for making this website!!

I want to recommend an additional feature to make website even better. Perhaps the problems could be chosen in a way such that none of the members have solved it, and if it is impossible, then perhaps there can be a warning message.

What do you think? I'd love to hear back from you.

    Thanks for your suggestion!

    Actually, the current functionality does the same, the problems are unsolved by all the users.

    And if such a contest can't be prepared, a warning message should be displayed. Only thing is — I couldn't test if the warning message is actually being displayed or not :(

Awesome website! Great Work!

I would like to request some features, (1) can you do something to make the points get decrease with time? and (2) of course a custom rating feature to have a track on progress.
