Reveal!

Reveal is a simple interactive game, best played as a group, where participants have to identify a partly visible image as quick as possible.

The game does not come with images to play. You can

• collect and compile them to your linking through any image search database,
• ask your favorite image generation AI to generate them for you,
• use your personal image collection to reminisce about your past, or
• do whatever else comes to your mind.

As AI gets smaller, we may add image generation on-the-fly in the future.

Settings

Further settings and the ability to select different images are available via the ⚙ in the top-right. Changed settings are persisted.

Image Sources

The game tries to load images from a couple of default locations before asking the user for manual selection. Not every platform supports every location. Access to files on Android and iOS differs from desktops.

• Desktops (in this order)
  • folder reveal in the user's pictures folder,
  • folder reveal_images next to the executable.
• Android
  • folder reveal in the user's pictures folder.
• iOS
  • folder reveal in "On My iPhone/iPad".

The user is able to manually select images via the settings, either selecting a folder from which all images are loaded or selecting individual images. Due to current limitations in the underlying framework, Android and iOS only support selecting individual images. On iOS it is possible to either select images from files or from Photos.

Trivia

A simple version of the game was initially created in a single evening using Python and Qt. The motivation to re-implement it with Tauri and Rust, although seemingly overkill, was to become familiar with the framework and the language. Another goal was to understand the feasibility of developing for multiple platforms (including mobile) from a single code base.

In terms of effort distribution, building the game itself took less than 1% of the time (no surprise there). About 80% of the time was spent setting up the tools¹, and the remaining time was spent dealing with platform-specific quirks that are not (yet) fully abstracted by Tauri.
