Einstein Puzzle — WebAssembly Port

Play it now: https://martg0.github.io/einstein-puzzle/

Einstein Puzzle is a free cross-platform open source remake of the old DOS game Sherlock, inspired by Albert Einstein's famous logic puzzle. The goal is to open all cards in a 6x6 grid using logical hints about relationships between card positions.

WebAssembly Port

This is a browser-playable port of lksj/einstein-puzzle, compiled from C++ to WebAssembly using Emscripten. The original game logic is unchanged.

What was added for the web port

• Emscripten/SDL2 build — SDL1-to-SDL2 compatibility layer (sdl1_compat.c) and scancode-to-keycode mapping for browser keyboard input
• ASYNCIFY support — allows the original blocking event loops to work in the browser, with all Command objects heap-allocated to prevent stack corruption
• Persistent storage — saves, settings, and Hall of Fame stored in IndexedDB via IDBFS
• Mobile/touch support — tap to confirm, long press (500ms) to eliminate; responsive layout
• Fullscreen — scales to fill screen while maintaining aspect ratio
• Reset saves — button to clear all persisted data

How to build

# Install Emscripten
brew install emscripten   # or via emsdk

# Build
make -f Makefile.emscripten

# Run locally
python3 -m http.server 8080
# Open http://localhost:8080/einstein.html
