Our non-profit website at Onlinechessgames.org or Knightvibeschess.games allows people to play Chess, Checkers or use a Chess engine for free with no sign-up! Our Chess and Checkers board can be used by 2 people with only 1 device! For chess, we simply rotate the board once a player makes a legal move and the next person is ready to play. You continue until a checkmate or stalemate is detected. If you get a pawn to the end of our board, you get to choose what peice you want to promote to, just like in normal chess. Alongside chess, we have a interactive checkers game. We use similar logic, we flip the board once a legal move has been made. In our checkers game, we have normal rules, checkers can only move diagonal forward. Another checkers rule we have is the rule were you have to take a peice and then take more with that same peice if you can. In addition, we have a built in chess engine that reccomends the best moves for both players. We use integrated stockfish to make the anylasis come to life! You can pick to use Chess engine mode or grandmaster mode,  Chess engine is way better, it will see way further ahead than the Grandmaster mode. We give intructions with how to install our Progressive Web App (PWA) On Mobile or Computer. To wrap it up, we are a free online chess website usable by anyone with Internet.
