Alchemical Engines

Alchemical Engines is a puzzle game about carefully filling out a grid with the four elements. Certain cells need to be solid, others need to be liquid. Some need to be hot, others need to be cold. It's up to you to fill out the grid correctly!

How to play

Alchemical Engines works similar to nonograms / picross puzzles. The numbers on the side determine which elements belong in which square. Remember,

• Earth is a cold solid
• Water is a cold liquid
• Metal is a hot solid
  
• Lava is a hot liquid

The blue numbers on the top and left determine which elements are solid and not:

The red numbers on the right and bottom determine which elements are hot and not:



Combining this info allows you to finally generate a full solution:

Your fastest times are recorded in the statistics page. Solving it under one minute gets you a wavy effect, and solving it in under 30 seconds gets you the exciting rainbow effect!

Controls

Click on the tray on the bottom right to select which element to place. Alternatively, use keyboard shortcuts:

1 - Water

2 - Earth

3 - Lava

4 - Metal

Left-click to place an element, right-click to remove an element. 

Enable/disable the timer, hint number animation (the slight rotation of the blue and red numbers), as well as the background tint in settings.

The help option in the pause menu will automatically fill 1-2 empty spots on your grid with the correct answer. It is disabled when your grid only has 1 empty spot.

Have fun!
