Best Electronic Chess Boards: Chessnut Air vs DGT vs Square Off

If you want a board that records your games automatically and lets you play online with real pieces, buy the Chessnut Air. It is the cheapest entry into the category that still does true piece recognition rather than square occupancy, it is thin enough to live on a desk, and its app bridges to online play. If you want the equipment the broadcast industry standardised on, or you already own DGT clocks and want the matched system, buy a DGT board, which The Chess Store stocks alongside the rest of the DGT range. Square Off is a different product wearing the same category label: it physically moves the pieces, costs considerably more, and plays slowly. And before any of it, the honest warning that the marketing pages skip: none of these boards is legal for you to use as your record of a rated game.

Model line-ups in this category turn over quickly and each manufacturer sells several boards under similar names. Confirm the exact model's connection type, power source, and app support on the listing before buying, because those differ between revisions of the same product family.

How these boards know what is on the board

This is the specification that separates real electronic boards from novelty ones, and it is worth understanding before you compare prices.

A cheap sensor board detects occupancy: it knows a square is filled but not by what. Software then infers the piece from the move history. That works until something goes wrong. Knock the board, set up a position from a book by hand, or promote a pawn, and an occupancy-only board loses the thread and needs a manual reset.

Chessnut and DGT both do piece recognition: each piece carries a passive identifying element, and the board reads the identity of the piece on each square. That is why you can dump the pieces on, set up a study position by hand, and the board simply knows what it is looking at. It is also why promotion works properly and why a mid-game bump does not corrupt the record. If a board in this price range does not state piece recognition explicitly, assume it is occupancy-only.

The trade-off is that the pieces are part of the system. Lose a knight and you are ordering a replacement from the manufacturer, not grabbing a spare from another set, and the pieces themselves are lighter and less pleasant in the hand than a good weighted tournament set, because they have electronics to accommodate.

Auto-recording is the actual reason to own one

Strip out the novelty and the case for an electronic board is one feature: everything you play or play through arrives as a PGN file without you writing anything down.

That matters in two places. First, over-the-board practice games at home stop evaporating. A club-strength player who plays a friend twice a week and never writes the games down loses the single richest source of material for improvement; a sensor board converts those into a database automatically. Second, and less obviously, it changes how you read a chess book. Playing a variation through on the board and then having that variation appear as a file you can push into an engine or a study, without transcribing anything, removes the friction that stops most people working through annotated games properly.

What it does not do is replace the paper record for club and tournament play. For that you still want a scorebook, for reasons covered below.

Playing online with real pieces

All three systems work the same way: the board pairs with a phone or computer, an app relays your moves to the online platform, and the opponent's replies come back as lights, sounds, or an on-screen prompt telling you which piece to move for them.

Three practical points. The relay adds a small amount of latency and you cannot premove, so this is a poor way to play bullet and a genuinely pleasant way to play a fifteen-minute game or a correspondence game. Support for a given platform lives in the manufacturer's app and depends on that platform's external-board interface, which the platforms control and occasionally change, so check the manufacturer's current list of supported sites rather than assuming. And you still need the screen nearby: the clock, the chat, and the resign button are on the phone, not the board.

Tournament legality: the honest answer

No electronic board in this article may be brought to a rated tournament and used as your record of the game. This gets asked constantly and the marketing copy is silent on it, so here is the shape of the rules.

Both US Chess and FIDE regulate electronic devices at the board, and both treat electronic scorekeeping as a separate, approved category. The published requirements for an electronic scoresheet device centre on the same idea: the device must record moves and nothing else. It must not evaluate a position, suggest a move, or give access to an engine or a database during play, and it must be on the approved list maintained by the federation. A sensor board whose entire function is to feed positions to an app that includes analysis fails that test on its face.

Electronic boards do appear at serious events, but supplied by the organiser and used for broadcast relay, with the players still keeping paper scoresheets. DGT's position in that role is the reason its equipment is the reference point in this category at all.

So: buy an electronic board for home, for online play, and for study. Take a tournament set, a clock, and a paper scorebook to the event, and if you have any doubt about a device you intend to bring, ask the tournament director in advance rather than at the board.

Where DGT still wins

DGT has been building sensor boards for the broadcast market for decades, and that history buys three things. Longevity and serviceability, because the product line changes slowly and the boards stay supported. Ecosystem, because DGT boards, DGT clocks, and DGT software are designed to work together and the combination is what event organisers deploy. And one thing Chessnut does not offer at the same maturity: a model with a computer built into the board, so you can play a rated engine opponent at a chosen strength with no phone involved at all.

The costs are price and bulk. DGT boards sit well above the Chessnut entry point, the wired models expect a computer nearby, and the wooden versions are furniture rather than something you slide into a bag.

Where Chessnut wins

Price of entry, thinness, and the fact that the board is rechargeable and wireless without paying a premium for it. For the specific job of "I want my home games recorded and I want to play online with pieces in my hand," it does everything the more expensive equipment does at a fraction of the outlay, and this site reviews it separately in more detail. The trade-offs are the ones you would expect at the price: lighter pieces than a proper tournament set, a plastic playing surface, and a dependence on the manufacturer's app that you are stuck with for the life of the board.

Square Off and the robot-board category

Square Off boards move the pieces themselves, using a mechanism under the board that drags them into place with a magnet. It is genuinely impressive to watch, it is the best gift in this whole category, and as a training tool it is the weakest of the three. Each opponent move takes seconds of physical travel, the mechanism cannot lift a piece over another so knight moves and castling look strange, and the price is the highest here by a wide margin. Buy it because someone will enjoy owning it, not because it will improve anyone's chess.

Who should buy which

• You want your home and online games recorded, on the smallest sensible budget: Chessnut Air.
• You want a board that plays you at a set strength with no phone in the loop: a DGT model with the computer built in.
• You already own DGT clocks or run broadcasts: stay in the DGT ecosystem.
• You want a gift that will impress a non-player: Square Off.
• You are buying to prepare for over-the-board tournaments: none of them. Buy a weighted tournament set, a clock, and a scorebook, and spend the difference on a coach.
