Play Checkers Against the Computer

Free, three difficulty levels, no download · Updated August 10, 2026

You do not need a second player. Checkers Arena includes a free computer opponent for American checkers (English draughts) on three difficulty levels — no signup, no download, no app. This page does something the usual "play checkers vs computer" page does not: it tells you exactly how strong each level is, in numbers, and how to beat it.

Why "easy" is so often too hard

Read the reviews of almost any checkers app and the same complaint comes back: the easy level is not easy. People set the difficulty to its lowest setting, lose anyway, and cannot tell whether they are bad at checkers or the setting is broken. Sometimes the hardest level even feels easier than the lowest — a sure sign that nobody ever checked.

The reason is almost always the same. Difficulty gets picked, not measured. Someone chooses a search depth that sounds about right for each level, ships it, and never plays the thousand games it would take to find out what those settings actually do to a beginner.

We made that exact mistake. An earlier version of our medium level searched much deeper than it does now, and when the levels were finally played against each other it beat easy 15–0–1. That is not a difficulty step; it is a wall. The live results agreed — players were winning roughly one game in ten against the default. The levels were re-tuned until easy took a real share of the points, and the numbers below are the result of that measurement rather than of somebody's judgement.

The three difficulty levels, in numbers

Two things decide how hard a checkers computer is: how far ahead it looks, and how often it deliberately plays something other than its best move. Most sites will tell you a level is "medium". Here are the actual settings:

Note what the middle column does not say. When the lower levels hold back they play their second or third best move — never a random one. That distinction is the whole difficulty design: a computer that throws pieces away at random is not easier to play against, it is just annoying, and beating it teaches you nothing. A computer that plays a slightly worse move keeps the game coherent and leaves you a real position to win.

At the current settings easy takes roughly 31 % of the points against medium over 44 games. That is what a step between levels is supposed to look like. Hard is deliberately a much larger jump — nobody lands there by accident, and it is meant to stay difficult for a long time.

Your choice is remembered between visits, so you will not find yourself back on easy next time you open the board.

How to beat the computer at checkers

A search-based opponent has predictable weaknesses, and they are not the ones people expect. It will not miss a two-move tactic — but it has no plan beyond its search horizon, and it is obliged to follow the rules even when they hurt. Five things that work:

1. Turn the forced-capture rule into a weapon

This is the single most useful idea on the page. Captures are compulsory in checkers, so offering a piece does not ask the computer whether it would like it — it removes every other move it had. You are not hoping it takes the bait; you are choosing its reply for it. Almost every two-for-one shot in the game starts this way.

2. Hold your back row

The pieces sitting on your own king row cost nothing to leave where they are, and while they stay put the computer cannot crown a piece behind them. Give them up last. Beginners advance them early because they feel idle; they are not idle, they are a wall.

3. Trade when you are ahead, avoid trades when you are behind

Every even exchange makes a one-piece lead proportionally bigger — a 12-to-11 advantage is slight, a 3-to-2 advantage is usually winning. The engine values material heavily, so it will generally accept the trade you offer. Use that: when you are up a piece, simplify.

4. Stay off the edge

A man on the rim has half the moves of a man in the middle and can never be captured back into play. The computer will happily let you drift there. The opening moves that push a man toward the centre are stronger for exactly this reason, and checkers strategy covers what to do with the middle once you have it.

5. Play the endgame out

The lower levels are at their weakest with few pieces on the board. It sounds backwards, but a shallow search sees less in an open endgame: there are fewer forcing moves to guide it and more empty board to cross, so two or three moves of vision buys almost nothing. If you reach a level ending against easy or medium, keep playing.

If you want to know whether a particular position was really winning, put it into the checkers move calculator afterwards — it will tell you the best move and who stood better.

How the computer plays

The opponent uses minimax with alpha-beta pruning and iterative deepening, running over the exact same rules engine that draws the board and validates every move in online games. That shared engine is why it cannot cheat: an illegal move is not something it is able to produce, rather than something it has been asked not to do.

Alpha-beta only pays off when the best move is examined first, so the search remembers which moves caused cutoffs earlier and tries those first, and it keeps a table of positions it has already evaluated — the same position frequently arises through more than one move order. On benchmark positions those two together cut the number of positions examined by roughly four fifths, which is what lets "hard" look as far ahead as it does inside a fraction of a second. The lower levels search too shallowly to benefit, which is part of why they stay fast and beatable.

"Up to ten moves" is honest about the ceiling rather than the guarantee. The search is bounded by a time budget as well as a depth limit, so it goes deeper in a sparse endgame than in a crowded middlegame. It always finishes a complete pass before moving — it never plays from an abandoned half-finished search.

What the computer cannot do

Two honest limits, because a page that only lists strengths is not much help when you are trying to win:

• No opening book. It works the opening out from general principles every single game. A player who has studied checkers openings can reach a comfortable position against it before it has anything concrete to calculate.
• No endgame database. It searches endgames like any other position. If you want positions played perfectly, that is the checkers endgame database, where every position with four pieces or fewer is solved exactly and can be played out move by move — two kings beat one in 17 forced moves, and the longest win in there takes 55. The playing opponent does not use that table, which is precisely why tip five works.

No download, no account, no server

There is no app to install and no registration. The board is a web page: it opens on a phone, a tablet or a desktop browser in a couple of seconds. The computer opponent itself runs on your own device, not on a server, which has one practical consequence worth knowing — a game against the computer keeps working even if your connection drops mid-game.

An account is optional and only matters for playing other people: it keeps your Elo rating and record across devices. Games against the computer are not rated, so nothing you do here can dent a rating.

A computer opponent for the other variants

The same engine plays three more games, each with its own rules rather than a reskin of American checkers:

• Brazilian draughts vs the computer — the same 8×8 board, but men capture backwards and kings fly.
• International draughts vs the computer — 10×10, 20 pieces a side, the tournament standard.
• Turkish draughts (dama) vs the computer — orthogonal movement, no diagonals at all, rook-like kings.

If you are unsure which to try, the guides hub lays the four out side by side.

Questions about playing the computer

Can I play checkers against the computer for free?

Yes. The computer opponent is free, needs no account and no download, and runs entirely in your browser. Pick a difficulty level and start. The game itself runs on your device, so it keeps working even if your connection drops.

How do you beat the computer at checkers?

Use the forced-capture rule against it. Because captures are compulsory, offering a piece does not ask the computer whether it wants it — it removes every other option, which is how most two-for-one shots begin. Beyond that: hold your back row so it cannot crown, trade pieces evenly while you are ahead, keep your men off the edge where they have half the moves, and play the endgame out, because a shallow search is weakest when few pieces are left.

Why is easy mode in checkers apps often so hard?

Because difficulty is usually guessed rather than measured. A level is set by picking a search depth that sounds right, and nobody plays enough games to check what it does. An earlier version of our medium level searched much deeper and beat easy 15–0–1 — that is not a difficulty step, it is a wall. It was re-tuned by playing the levels against each other until easy took a real share of the points.

How strong is the checkers AI?

It depends on the level, and the difference is not a marketing word. Easy looks two moves ahead and plays its second or third choice about a third of the time. Medium looks three moves ahead and does that roughly one move in seven. Hard looks up to ten moves ahead within its time budget and never plays anything but the best move it found.

Which difficulty should I start with?

Easy, which is why it is the default. Winning your first game is the reason people come back, and easy is set up so a beginner can win without the computer throwing the game away. Move up when you start winning comfortably. Your choice is remembered, so you will not drop back to easy on your next visit.

Does the computer cheat at checkers?

No. It plays through the same rules engine that validates every move on the live board, so an illegal move is not something it could make even if it wanted to. It also sees exactly what you see: there is no hidden information in checkers, so there is nothing for it to peek at. If a jump felt unfair, it was almost certainly the forced-capture rule, which applies equally to both sides.

Can the computer be beaten?

On easy and medium, regularly. Hard is a serious opponent that will punish a loose move, but it has no opening book and no endgame database, so it plays the opening on general principles and can be outplayed in a long endgame by someone who knows the theory. We do not claim a rating for it — that would need hundreds of games against rated humans, which nobody here has played.

Do I need to download anything to play checkers vs the computer?

No. There is no app, no install and no registration. The board is a web page, so it opens on a phone, tablet or desktop browser in a couple of seconds, and the computer opponent runs on your own device rather than on a server.
