Inspiration

Arcade machines are a fun way to bring quick, replayable games into any world. I wanted a blackjack cabinet that not only plays great, but also serves as a clear reference for creators who want to build their own arcade machines or learn advanced CustomUI patterns.

What it does

The Blackjack Arcade Machine is a self-contained cabinet with a fully interactive UI and simple game logic you can study and remix.

Challenges I ran into

Designing a clean example for advanced CustomUI while keeping blackjack rules correct was the main challenge. I needed to:

  • Keep the UI stateless and reactive using bindings instead of scattered flags.
  • Minimize GC churn by reusing bindings and preallocating card slots.
  • Cover edge cases like soft 17, blackjack payouts, and early resolution while keeping the code easy to read.
