You’ve seen it. Spock stares intensely at a stack of transparent plastic squares, moves a piece diagonally through the air, and Checkmate. It looks cool. It looks smart. But honestly, most people think a three dimensional chess board is just a prop from a 1960s sci-fi set. It’s not. It’s a real, playable, and incredibly frustrating brain-melter that has existed in various forms long before Gene Roddenberry needed a way to show that Vulcans were geniuses.
Most people get it wrong. They think it’s just "regular chess but higher." That's a mistake. When you add the Z-axis, the geometry of the game doesn't just grow; it explodes.
The Reality of the Multi-Level Game
We should probably clarify something right away. There isn't just one three dimensional chess board. If you go looking for one, you’ll find the Raumschach version, the Star Trek version (officially known as Tri-Dimensional Chess), and several other variants that never quite made it out of the niche hobbyist basements.
The most famous one—the one with the three main levels and the four tiny "attack boards"—was basically invented by Andrew Mainwaring and Franz Bieber back in the day, then refined for the screen. It’s a beast. In a standard 2D game, your Rook moves in four directions. On a 3D board, the spatial relationship changes everything. You aren't just looking left, right, forward, and back. You’re looking up-forward-left. Your brain isn't wired for it. Not naturally, anyway.
It’s confusing.
Think about the Bishop. In 2D, it stays on one color. In 3D variants like Raumschach (which uses a 5x5x5 cube), the Bishop moves through the vertices. It can slice through the "body" of the cube. If you aren't paying attention, a piece three levels above you can swoop down and take your Queen before you’ve even finished your coffee. It’s a vertical nightmare.
Why 3D Chess Is Different From What You Think
Most players start with the assumption that they can just apply their 2D tactics. That is a fast track to losing. In a three dimensional chess board environment, the "center" isn't a 2x2 square of territory. It’s a volumetric core.
Maack, the guy who developed Raumschach in the early 1900s, realized that the traditional 8x8 board was too big for 3D. If you stacked eight 8x8 boards, you’d have 512 squares. That’s too many. Nobody has that kind of time. He scaled it down to a 5x5x5 grid. That’s 125 positions. Even then, the complexity is staggering.
125 squares.
Three dimensions.
Total chaos for the uninitiated.
The pieces often have to be modified too. In many versions, you have a "Unicorn." It’s not just a fancy name. The Unicorn moves specifically through the tri-planar diagonals—the ones that connect the opposite corners of a small cube within the larger board. It’s a piece that literally cannot exist in a 2D world.
The Star Trek Influence and the Rulebook Struggle
We have to talk about the "Tri-D" board from the show. For years, fans just moved pieces around randomly. It looked good for the camera. However, in 1976, Andrew Bartmess published the Star Trek Strategic Operations Simulator, which finally gave the world a semi-coherent set of rules for that specific board.
It uses three 4x4 "Main Levels" and four 2x2 "Attack Levels." The attack levels are movable. Yes, you can actually move the board itself as a turn. This adds a layer of tactical positioning that makes standard chess look like checkers. You aren't just moving pieces; you're shifting the geography of the battlefield.
It’s wild.

Some people argue that the Star Trek version isn't "real" chess because it’s too clunky. They prefer the 5x5x5 cube. But honestly, the Tri-D board is what people actually buy for their dens. It’s a conversation piece. It says, "I am probably smarter than you," even if you haven't actually played a full game since 2014.
The Mental Load: Why Your Brain Breaks
Playing on a three dimensional chess board requires a high level of "spatial visualization." This isn't just a buzzword. It’s a specific cognitive ability to rotate objects in your mind.
When you play 2D chess, you see patterns. You see a "pin" or a "fork" as a flat geometric shape. In 3D, those shapes become 3D volumes. A fork might involve a Knight on level 2 attacking a King on level 3 and a Rook on level 1. Tracking that involves a massive amount of "working memory."
It’s exhausting.
Most beginners experience what players call "level blindness." You focus so hard on the board where the action is happening that you completely forget the board hovering six inches above it. It's like being a submarine captain who forgets that planes can drop depth charges from the sky.
Getting Your Hands on One
If you actually want to try this, you have a few options. You can buy the official Franklin Mint sets, but they’ll cost you a limb. They’re beautiful—gold and silver plated pieces, heavy glass tiers—but they’re more like jewelry than gaming equipment.
Most serious players build their own or use software. There are several open-source 3D chess programs, and some VR versions that actually make it easier to see the lines of sight. Seeing the board in VR is a game-changer because you can physically lean in and look "through" the levels.
Common Misconceptions
- It’s just a gimmick. Wrong. While it started as a prop for some, the mathematical depth is objectively greater than 2D chess.
- The rules are the same. Not even close. You have to learn how pieces transition between levels, which usually involves specific "staircase" movements or coordinate shifts.
- Grandmasters are all good at it. Actually, many 2D masters hate it. It ruins their intuition. They rely on "chunking"—recognizing patterns instantly—and 3D chess breaks those patterns.
How to Actually Start Playing
Don't just buy a board and start moving. You’ll quit in twenty minutes.
Start by mastering the movement of a single piece across levels. Take a Rook. Learn how it moves vertically through the same coordinate on different boards. Then try the Bishop. Once you realize the Bishop moves through the "edges" of the cubes, your perspective shifts.
The biggest hurdle is the coordinate system. In 2D, it’s A1 to H8. In 3D, it’s usually Level-Coordinate (e.g., Level 1, A1). Keeping track of "Level 3, C4" while your opponent is eyeing "Level 2, B2" is the whole game.
Tactical Insights for the Bold
If you find yourself sitting across from a three dimensional chess board, remember the "Vertical Pin." If you can align your long-range pieces (Queen or Rook) so they cover the same coordinate across all levels, you effectively create a wall. Your opponent can't move through that vertical shaft without being captured.
Also, watch the attack boards. In the 3D variants that use them, these are your flankers. Use them to bypass the congested central levels. Most players get bogged down in the middle tiers, forgetting that the mobile levels can be repositioned to create a direct line to the King.

The Future of the Z-Axis
Is 3D chess the future of the game? Probably not. Standard chess is already "solved" enough by computers to keep us busy for a thousand years. But as a tool for cognitive training, or just as the ultimate "flex" for your game room, the three dimensional chess board remains the gold standard.
It challenges the way you perceive space. It forces you to think in volumes rather than planes. And honestly, it just looks incredible.
Actionable Next Steps
- Download a Simulator: Before spending $300 on a physical set, try a digital version like Parmenides 3D Chess or search for 3D variants on tabletop simulators. It’ll tell you if your brain can handle the Z-axis.
- Study the Raumschach Rules: If you want a "pure" mathematical game, look up the 5x5x5 rules. It’s more balanced than the Star Trek version and serves as a better entry point for serious tacticians.
- Check the "Attack Board" Mechanics: If you go the Star Trek route, spend an hour just practicing "board movement." Learning when to shift a 2x2 mini-board is more important than learning piece moves.
- Visualize the Shafts: Practice seeing the board as a series of 64 vertical shafts rather than three flat planes. This perspective shift is what separates people who "play at" 3D chess from people who actually play it.
