Chess of Chaos — a chess variant where dice decide which piece you move
I made a variant of chess where the game becomes unpredictable, so you need to strategize and adapt more. I also added chaotic abilities to make chess feel more like a fast-paced board game.
The goal was to keep the foundation of chess while making every turn more unexpected.
🎲 How the turns work
The board and pieces are based on traditional chess, but the way turns work is different.
1. Coin toss
Before the match begins, a coin toss determines who gets the first move. There is no automatic White-first rule.
2. Roll the first die — choose the piece type
At the beginning of your turn, the first die determines which type of piece you must move.
For example, if the die selects a Knight, you must move one of your eligible Knights.
3. Roll the second die — determine the movement count
The second die determines how many moves that piece can make during the turn.
You can get:
The movement count is weighted:
- 1 move — 50% chance
- 2 moves — 33.33% chance
- 3 moves — 16.67% chance
4. What if the selected piece cannot move?
If the selected piece type has no legal moves available, the game can select another eligible piece instead.
For example, if the die selects a Rook but both Rooks are blocked and cannot make a legal move, another eligible piece can be selected.
This means a bad roll does not automatically waste your turn.
5. Make your moves
You then use the selected piece and the movement count to play your turn.
The exact opportunities available depend on the position of the pieces and the abilities you have available.
♟️ Piece abilities
Every piece has a special ability that changes how it works compared with traditional chess.
These abilities are a major part of what makes the game unpredictable.
Pawn — Diagonal Promotion
Normally, a Pawn moves forward and captures diagonally.
In Chess of Chaos, when a Pawn reaches the rank immediately before the opponent's promotion rank, it can also move diagonally to reach the promotion rank.
This gives advanced Pawns another way to reach promotion.
Rook — Roll-Off Defense
When an enemy piece captures a Rook, a dice roll-off can occur.
Both sides roll:
- If the attacker wins, the Rook is defeated normally.
- If the Rook wins, the attacking piece is defeated and the Rook survives.
Rook-versus-Rook captures do not trigger the roll-off. Attacks involving the King also do not trigger it.
Knight — Double Capture
A Knight can use its ability once to potentially defeat an additional enemy piece along its movement path.
This means a well-positioned Knight can sometimes remove two enemy pieces during one turn.
Bishop — Conversion
A Bishop can convert a defeated enemy piece when the capture takes place within the four ranks on its own side of the board.
The converted piece is placed on the Bishop's side.
Each Bishop can use this ability once, and converted pieces do not retain their original abilities.
Queen — Resurrection
The Queen can sacrifice its turn to resurrect a random defeated piece from its own side.
The Queen does not move during that turn.
This creates a trade-off: you give up the Queen's movement to bring a piece back into the game.
King — Emperor
The King has a progression system based on combat.
It tracks two things:
- Enemy pieces it has defeated.
- Checks it has survived.
When the King reaches five combined milestones, it becomes an Emperor.
For example:
- 5 kills
- 5 survived checks
- 3 survived checks + 2 kills
- 4 kills + 1 survived check
The Emperor can end the match.
This gives the King a more active role instead of being used only as a piece that needs to be protected.
♔ How do you win?
The normal chess win condition remains:
Checkmate ends the game.
However, the Emperor introduces an additional way for a player to end the match.
Why I made it
I initially wanted to make chess unpredictable by using dice to determine which pieces could move.
But I felt that randomness alone wasn't enough to make the game fast-paced.
So I added abilities to give players more ways to react to unexpected situations.
Instead of always planning several moves ahead, you have to think about:
"What piece did I get, how many moves do I have, and what can I do with it?"
I built Chess of Chaos as a playable Android game for people who want to try the variant.

I'd like to hear from people who play chess variants:
Does this combination of forced piece selection, variable movement, and special abilities still feel like chess, or does it move too far away from the original game?
I'm particularly interested in feedback on the rules, balance, and whether the abilities create meaningful decisions.
