I'm thrilled to announce that HEX:ARENA is now officially live on the Google Play Store! As an AI engineer, building this game gave me the perfect opportunity to merge classical search algorithms with modern LLM-assisted development workflows.
Engineering the AI Opponent
Standard state-machine logic wasn't going to cut it for a hex-based strategy game; the state space is simply too massive and deterministic patterns become obvious. To provide a deeply challenging and dynamic opponent, I engineered a custom Minimax algorithm equipped with Alpha-Beta pruning.
Deploying computationally expensive search trees on mobile devices is notoriously difficult. Deep recursive evaluations rapidly drain battery life, block the main UI thread, and trigger native Out-Of-Memory (OOM) crashes due to excessive object allocation during the search.
Accelerated by Generative AI
To overcome these hardware constraints and accelerate development, I leveraged generative AI tools as my co-pilots. I used Google's Antigravity (Claude) to iterate on UI/UX design, and Codex (OpenAI) to assist with the core engineering. This workflow allowed me to rapidly refactor the engine's state representation—eliminating object allocation entirely with in-place board mutations—and offload the intensive computation safely.
This AI-assisted engineering approach allowed me to build, optimize, and ship the entire game in just two months.
Give It a Go!
Releasing HEX:ARENA has been incredibly rewarding. If you're interested in AI, strategy games, or just want to try out a challenging mobile puzzle against a highly-optimized Minimax agent, I invite you to give it a go.
