Antimatter
Match opposite word tiles in a mahjong solitaire puzzle game
Visit linguabase.org ↗What is Antimatter?
Antimatter is a word puzzle game that combines mahjong solitaire mechanics with antonym matching. Players match tiles representing opposite words across 20 playable levels. The game draws from a semantic graph containing over 23,000 antonym pairs and 100,000+ words built through manual lexicography and machine learning inference.
The puzzles are algorithmically generated and randomly selected on each reload, offering varied challenges. The maker notes that frontier LLMs struggle to create interesting antonym puzzles without specialized prompting, so the game uses graph traversal techniques to explore diverse language territories. The front-end was built with Claude Code.
