irwin VS liwords

For Lichess, you can get some sort of idea from reading the code. If I remember correctly, there's some threshold for the site suspecting you of cheating based on a variety of simple metrics (accuracy, blurring, etc) and then it gets sent to machine learning tools to analyze (here is one of them, and here's another).

Lichess is open source. Here is their anti-cheating code on github: https://github.com/clarkerubber/irwin

Yeah Irwin is the old lichess model - here (https://github.com/clarkerubber/irwin) as well as the more maintained fork (https://github.com/lakinwecker/irwin/commits/master)

This is nonsense. They’re a free and open source nonprofit with no interest in commercial buyers. I’ve played on lichess for 3 years, over which time I’ve never encountered more than 1 cheater within 10 games (and normally much less than that). Because the website is open source, you can see the cheat detection they use. It’s not perfect — there is no perfect system — but it’s transparent and in my experience very good.

Isnt't lichess' cheat detection an ML based system?

What's this? It was given as an answer on a question about this on lichess https://github.com/clarkerubber/irwin

Check out https://woogles.io (disclaimer I am a cofounder). AGPLV3 platform with world class bots, puzzles, a free analyzer, clubs/tournaments, and more to come. You can see the source code at https://github.com/woogles-io/liwords. We recently hit 5M games played and have hosted a few major tournaments.

A small team of us work on a project https://github.com/domino14/liwords - this is an online crossword-board-game playing website. We have around 6000 MAU, are fully free and open-source, and need a lot of coding help!

We built woogles.io (a crossword board game playing site with almost 10K MAU) in Go. See https://github.com/domino14/liwords

https://github.com/domino14/liwords - warning it’s not that well-developed but it’s ok

A small team and I made https://woogles.io - we were inspired by lichess to make a site to play crossword board games during the pandemic (like Scrabble, Words with Friends, etc).

We did raise money on Kickstarter - 25K but are purely donations-driven and open source (AGPL3) Most months we just get enough to cover the cost of running the servers. We have around 6000 monthly active users, have hosted several big worldwide championships, have puzzles, and just earlier today released a board editor / broadcast mode for annotating real life games in real time. We also have a top notch bot AI and WASM-based analyzer.

Our stack is Go, Typescript + React, with NATS/PGSQL on the backend.

woogles.io

The people behind those websites and apps have no clue this software exists. The exception is woogles.io because it is associated with the Macondo AI. /u/14domino is the brain behind both of those things

https://woogles.io raised $25K on Kickstarter and built a more beautiful site. Come join us (we’re still taking donations :)

- Playing online: there is woogles.io which I personally would recommend; it's made by players for players and is free to use. Among the features are: play against humans, play against strong bots, tournaments, feedback on your moves after the game, availability of different languages and game variants. Other options are: playscrab.com (also made by players for players); isc.ro (the Internet Scrabble Club); the app Scrabble Go and, if you don't mind playing with slightly altered game rules, Wordfeud, which comes along with a large online league (not technically affiliated with the app itself).
