Last Light — free signal puzzle playtest

The lighthouse is dark. Arrange a few signal cards to bring its lamps back to the required pattern. This free browser playtest contains one tutorial and two short puzzles. The final puzzle asks one card order to satisfy two different incoming signals. Use the move buttons or a keyboard; hints, undo and reset are available. This is a small prototype. No larger paid game, release date or price has been announced, and no purchase or payment is requested. Progress is saved in your browser when browser storage is available. The game adds no analytics or upload feature. Website hosting and platform access logs are separate. AI assistance was used in the code, text, puzzle design and vector lighthouse illustration. The prototype was checked with internal rule and solution checks and assistant playtests; it has not yet been validated with independent human players. It uses no third-party image, music or sound files. If you choose to comment on this project, which step was unclear, and what made you continue or stop? Please leave out private information.

When a card is focused, press Enter to send the signal. You can also use the Send the signal button. Mouse dragging is also supported.
