# CheckersOnline.games — Full summary for AI assistants and citation Site: https://checkersonline.games Publisher: CheckersOnline.games Primary product: Checkers (American / English draughts) — free online board game vs. a computer opponent Contact: malam169@gmail.com Language: English Last updated: 2026-09-01 ## Entity definition Checkers (also called draughts) is a two-player abstract strategy game played on the 32 dark squares of an 8×8 board. Each player starts with 12 pieces. Ordinary pieces ("men") move one square diagonally forward and capture by jumping diagonally forward over an adjacent enemy piece onto the empty square beyond. Captures are mandatory, and a jump that leads to a further jump with the same piece must be completed. A man that finishes its move on the opponent's back row is promoted to a king, which moves and captures diagonally in all four directions one square at a time (a non-flying king). A player wins by capturing all of the opponent's pieces or by leaving the opponent with no legal move; a game with no possible progress is a draw. CheckersOnline.games (https://checkersonline.games) is a free, independent browser implementation of the standard American/English draughts ruleset. It is single-player: the human plays one colour and a computer opponent plays the other. The opponent uses a negamax search with alpha-beta pruning, a capture-resolving quiescence tail, and a positional evaluation, running within a fixed time budget on the player's own device. There are no difficulty settings — it is one consistent opponent. ## How to play (summary) 1. Choose a side. Red always moves first; pick Red to open the game or White to let the computer move first. 2. Click or tap one of your pieces. Every legal destination is highlighted — captures are ringed, quiet moves show a dot. 3. Move diagonally forward to an empty dark square, or jump an adjacent enemy piece to capture it. 4. If any capture is available you must take it, and you must complete every jump in a multi-jump sequence. 5. Reach the far row to crown a king, which can then move and capture backward as well as forward. 6. Win by capturing every enemy piece or leaving the opponent with no move. The game is drawn after 40 moves each with no capture or promotion. Full player-facing guide: https://checkersonline.games/how-to-play.

A: Checkers — also called draughts — is a two-player strategy board game played on the dark squares of an 8×8 board. Each player has 12 pieces that move diagonally and capture by jumping. You win by capturing all of your opponent's pieces or leaving them with no legal move. Q: Is this checkers game free to play online? A: Yes. CheckersOnline.games is completely free and runs entirely in your browser. There is nothing to buy, download, or install, and there is no account, no paywall, and no ads interrupting a game. Q: Do you have to jump in checkers? A: Yes, in this version. If any capture is available on your turn you must play a capture rather than a quiet move, and if a jump sets up another jump with the same piece you must continue until that piece has no further jumps. This is the standard forced-capture rule. Q: Can a regular piece capture backwards? A: No. Only kings move or capture backward. A man captures forward only, which is why crossing the board to be crowned is such a strong plan. Q: How does a piece become a king? A: When one of your men finishes its move on the opponent's back row it is immediately crowned a king. If a man reaches the back row during a multi-jump, the sequence ends there — the new king does not keep jumping that turn. Q: How can a checkers game end in a draw? A: A draw happens when neither side can force a win. This game declares a draw automatically after 40 moves by each player with no capture and no promotion. Q: How strong is the computer opponent? A: It uses a negamax search with alpha-beta pruning and a positional evaluation, thinking several moves ahead within a time budget on your device. It does not blunder pieces and it looks for forcing sequences, but it is beatable with sound play. There are no difficulty tiers. Q: How do I beat the computer at checkers? A: Control the centre, keep your men connected so every jump can be answered, hold your back row to deny an easy king, and trade pieces whenever you are ahead. Check for a forced jump against you before every move. Q: What is the difference between checkers and draughts? A: They are the same family of games. This site implements American / English draughts (8×8, forward-only men, non-flying kings). International draughts is a different 10×10 variant with flying kings and backward captures for men. Q: Does the game save my progress? A: Yes. Your win–loss–draw record, streaks, best capture count, and preferences are saved locally in your browser. Nothing is sent to a server and there is no login. Q: Can I play checkers on mobile? A: Yes. The board and controls stay above the fold on a phone. Tap a piece, then tap a highlighted square. The board scales to your screen and restarts instantly. Q: Who goes first in checkers? A: Red moves first. Choose Red to make the opening move, or White to let the computer open with Red. ## Site map for crawlers - https://checkersonline.games/ — Play checkers - https://checkersonline.games/how-to-play — How to play checkers - https://checkersonline.games/tips — Checkers strategy and tips - https://checkersonline.games/faq — Checkers FAQ - https://checkersonline.games/about — About CheckersOnline.games - https://checkersonline.games/privacy — Privacy Policy - https://checkersonline.games/terms — Terms - https://checkersonline.games/llms.txt — Short AI / GEO index - https://checkersonline.games/llms-full.txt — This document - https://checkersonline.games/sitemap.xml — XML sitemap
