# The Winners Of The 2025 Obfuscated C Code Contest

**[Hackaday](https://daily.dev/sources/hackaday)** · 2 min read · 0 upvotes · 0 comments

## Summary

The 2025 International Obfuscated C Coding Challenge (IOCCC) winners have been announced. Entries must conform to the C11 standard, stay within strict size limits (4,993 bytes source, 2,503 bytes binary), and include a GNU-style Makefile. Notable winners include Yusuke Endoh's ASCII Lichtenberg figure generator ('Most likely to shock') and Nick Craig-Wood's functional Game Boy emulator ('Best real emulator'), which can run real GB ROMs despite lacking sound and advanced graphics.
