Unfortunately, this post will be without diagrams because images of classic chess pieces are not suitable for describing this game. That's why I'm linking my blog here on the site where you can see the visuals of the game. Of course, I could provide links to third-party resources (like BGG) where the rules are published, but these links will not be displayed here.
Imagine a game where the board is filled to the brim with pieces. They do not move. They are static protocols with a fatal trigger. Your move is not about where to go, but about which of your own pieces to erase first.
They disappear one by one. Each disappearance is not a loss, but a calculation. Strength becomes vulnerability. Victory is the art of planning your own annihilation one move ahead of your opponent.
Its complexity is not light, not medium, not advanced. It is paradoxical. The rules fit into a single sentence. Its depth lies in the exponential branches untouched by Go or classical chess.
This is not a new game. It is a new operating system for conflict. It uses the language of chess to tell a story that chess could never tell.
Introducing. EXPTIME CHESS. Chess played by deletion. The only way to move forward is to erase your pieces from the board. A system where your erasure is the tactic.
EXPTIME CHESS
Quick Rules
Objective: Leave your opponent with no pieces at the start of their turn.
Board & Pieces: Standard 8×8 board. Each player has 32 pieces:
8 Recurser
8 Anglitch
8 Domerror
8 Kernelix
Setup (Mirror Placement)
The game starts with an empty board. Players alternately fill ranks, mirroring each other.
1. White places any 8 pieces on the 1st rank (a1–h1).
2. Black mirrors them on the 8th rank (a8–h8).
3. Black places any 8 pieces on the 7th rank (a7–h7).
4. White mirrors them on the 2nd rank (a2–h2).
5. White places any 8 pieces on the 3rd rank (a3–h3).
6. Black mirrors them on the 6th rank (a6–h6).
7. Black places their last 8 pieces on the 5th rank (a5–h5).
8. White mirrors them on the 4th rank (a4–h4).
The board is now full (64 pieces: 32 White, 32 Black).
Player's Turn
Players take turns, starting with White.
An attack is mandatory if possible. Your piece can move along its trajectory onto a square occupied by ANY other piece (friendly or opposing). You must choose one such attack.
WARNING! When attacking, your attacking piece is immediately removed from the board. The attacked piece remains in place (does not move, change color, or owner).
If no attacks are possible: Make a standard move with any of your pieces to an empty square.
How Pieces Move
Recurser (NN): Makes several consecutive knight leaps (2+1) in the same straight-line direction (Nightrider).
Anglitch (B+NN): Moves as a Bishop or as a Recurser.
Domerror (R+NN): Moves as a Rook or as a Recurser.
Kernelix (K+NN): Moves as a King (one square in any direction) or as a Recurser.
End of Game: The game ends when it is a player's turn to move and they have none of their own pieces left on the board. That player loses.
Core Principle: You do not capture — you sacrifice your own pieces to force your opponent to do the same. Victory goes to whoever better calculates the sequence of these forced sacrifices.
As you can see traditional capture is replaced by a mandatory self-deletion protocol. The state vector of the game evolves not through piece movement, but through the controlled removal of one's own units. Each turn, a player must select one of their pieces to erase itself by initiating an "attack" on any intersecting target — ally or foe. The target remains; the aggressor is deleted. This creates a dynamic where positional advantage stems not from controlling space, but from orchestrating sequences of forced self-sacrifice. Victory is achieved not by eliminating the opponent's army, but by engineering a terminal state where the opponent is compelled to delete their final unit on their own turn. The board is static; the combinatorial explosion is absolute.
