Kurzbeschreibung des Wettbewerbs

I have added a perfect 3D-Simulation of the CURTA I
Who can rebuild the Curta calculating machine for me, based on this 3D simulation? The calculation functions should be directly accessible on the 3D model, including setting the numbers on the dials, operating the crank and the reset lever, and reading the result from the top. The Curta calculating machine should function and calculate just like the real thing.

I want to bring the legendary Curta mechanical calculator to life as a modern simulation game for mobile. The goal is a faithful, interactive recreation that lets adult players feel the click-and-crank experience, solve real calculations, and discover the device’s remarkable history along the way.

Core vision
• Appearance and design: a high-fidelity 3-D Curta model with accurate textures, shadows, and the unmistakable crank action.
• Functional mechanics: every turn, pull, and reset should process numbers exactly as the original does, so users can perform authentic addition, subtraction, multiplication, and division inside the app.
• Historical context: short unlockable vignettes or voice-over snippets that tell the story of Curt Herzstark, the calculator’s post-war production in Liechtenstein, and its cult status among collectors.

Game flow
Players start with a brief tutorial, then enter calculation challenges and speed-run modes that test precision under time pressure. Successful runs reward archival photos or anecdotes to deepen engagement, keeping the tone sophisticated enough for an adult audience yet approachable for anyone curious about vintage tech.

Preferred stack
Unity, Unreal Engine, or Godot are all fine if they deliver smooth cross-platform performance on iOS and Android. Please choose whichever engine you can leverage to reproduce tactile feedback, realistic audio clicks, and physics-based crank resistance.

Deliverables
• Playable mobile build (iOS & Android)
• Source code with clear comments
• Optimized 3-D assets and textures for the Curta
• Calculation algorithm unit-tested against real Curta results
• Short historical content modules (text or narrated)
• Setup and deployment documentation

Acceptance criteria
1. Calculations match verified Curta outputs for at least 50 random test cases.
2. Frame rate remains above 50 fps on mid-range 3-year-old devices.
3. All historical modules unlock correctly after corresponding challenges.
4. App passes Apple TestFlight and Google Play internal test tracks without critical crashes.

If you are passionate about retro engineering, precision simulation, and elegant UI, I’d love to see how you can turn this cult classic into an engaging digital experience.

    can you please extend for one day only, i created the realistic 3d model, the object is controllable like the real object with realistic sound effect and it show the correct results and the correct register, however i lost all the project files due to a unity crash the whole scene is gone when the remining contest time is just 4 hours. #extended

    I think all participants should only pitch actual work instead of multiple AI generated images. Because this project is of Mobile app development simulation game. So, contest holder can pick good entries from that.
