## The project behind this entrance

Lichess identifies itself as a free, open-source chess server. Its homepage offers a lobby, a challenge-a-friend path, computer play, puzzles and learning tools.

## Starting and choosing your setup

Choose the mode that matches your goal before entering a session. A game against the computer is different from a public lobby game or a chess puzzle; follow the host’s account requirements for that mode.

The homepage is a service entrance, not proof that we played an online opponent. Network restrictions may affect its separate asset host even when the main page is readable.

## Why it is in this collection

This is an additional browser discovery selected to broaden the directory. It is not presented as a game shared by Radiant or as a title supported by the Windows optimizer.

## Questions and answers

### Can I choose a computer opponent?

The current homepage offers Play against computer as a separate option.

### Was this checked in a completed play session?

No. This directory reviewed the project page or creator documentation. Loading a page does not verify a completed game, a multiplayer connection or device performance.

## Sources and review

Source review: 2026-10-10. Gameplay and performance are not tested by this directory.
