Description #
Malbolge is a notoriously esoteric programming language, designed to be virtually impossible to use. It was created as a parody of difficult programming languages and is infamous for its mind-bending syntax, self-altering code, and cryptic execution model.
History #
Malbolge was created in 1998 by Ben Olmstead. The name references the eighth circle of Hell from Dante’s Inferno, where fraudsters are punished — a fitting metaphor for the chaotic experience of coding in it.
Key milestones:
- Took two years before anyone wrote a working Malbolge program
- Uses trinary (base-3) arithmetic and self-modifying instructions
- The first “Hello, World!” program was generated by a beam search algorithm, not by hand
- Malbolge has inspired many other “joke” or tortureware languages like INTERCAL and Brainfuck
Hello World Code #
('&%:9]!~}|z2Vxwv-,POqponl$Hjig"ED\CB]@?>=<;:876📝 Yes, this is actually a valid Hello World program in Malbolge!

- Visit https://tio.run/
- Select Malbolge and paste the code
- Click Run
Locally: #
Malbolge interpreters are rare. Best run it online via TIO or Esoteric Languages IDEs.
Key Concepts #
- Self-modifying code — instructions change after execution
- Trinary arithmetic — operates in base 3 instead of base 10
- Encrypted opcodes — each command is mapped through a cryptographic table
- Limited character set — valid characters must fall into specific memory regions
- Execution jumps — instruction flow is hard to predict
- Memory-wrapped behavior — like a circular buffer
- Cryptic syntax — looks like random punctuation
- Write-only design — nearly impossible to read or debug
- Instruction encryption — determined by memory and pointer values
- Esoteric by design — intentionally hard to understand and use

Fun Facts #
- Malbolge was not tested before release — the creator had no idea if it worked
- It took two years and AI to write a working Hello World program
- Some Malbolge programs are shorter than their explanations
- The language is so confusing, it has been described as “programming from a parallel dimension”
- No serious application has ever been written in Malbolge — by design
