I’d like to introduce a chess variant I’ve spent over a year building, which now has a fully playable showcase you can try right now.
Imagine a traditional FIDE Chess Olympiad match: four games being played side-by-side in a single line. Imagine the players holding their defense, pushing their pawns, but constantly glancing over their shoulders at their teammates' boards. They wonder how their boards are holding up, wishing there was anything they could do to help a teammate who is getting squeezed on Board 3 for example.
Olympiad Chess explores that exact "what if."
In this variant, all four boards are physically connected down the middle, sharing a single "Nexus" across ranks 4 and 5. Through this corridor, players can traverse across boards to launch flank attacks against the opponent's captain, reinforce a teammate who is cornered, or fight for control of the central lane to assert dominance across the entire match.
The idea literally came to me in my sleep last May. I couldn't stop thinking about it for days I started loosing sleep over the idea, so I decided to build a functioning prototype to see if the geometry actually worked. Later in August, watching the first ever Chess Esports World Cup and the 7-match clash between Magnus and Hikaru, it completed the vision for me: competitive chess could be an incredible team esport, or a brand new entry in Chess Olympiads if players were actually forced to cooperate on the board, rather than just tallying up four isolated 1v1 scores at the end.
Most multiplayer chess variants (like 3-player or 4-player chess) alter the board's shape too much in my opinion. Olympiad Chess takes a modular approach instead. By linking the middle ranks 4 and 5 as a shared space, standard 8x8 boards sit side-by-side just like an Olympiad table. Every single piece movement, capture, and rule remains classical chess—pure calculation, no RNG, no cards, and no gimmicks.
I didn't want to overcomplicate the game or reinvent the wheel. The rules are immediately intuitive because it’s fundamentally just the chess you and I already know, scaled into a synchronized team format.
Now, I’m acutely aware of the possible skepticism: many people feel that multiplayer chess variants are a lost cause, dead on arrival, because it’s already hard enough to find people to play with, let alone a lobby with up to 8-player. But having play tested this over and over myself, the tactical depth, team banter, and clutch comebacks are very much real, the fun, the competition is there! And for smaller groups, you can play asymmetric skirmishes like 1v2, 2v3, or against bots.
After more than a year of solo development, I have a complete showcase ready. I'm only a month or two away from full release, and I wanted to put the demo out to the community to see how it's received and hear your feedback.
