The Cauldron Challenge

Click / Tap to spawn particles ! 

The Cauldron Challenge is a science-inspired chemistry and cooking game where every ingredient is simulated as a tiny particle. Add ingredients, control the burner, and manage microscopic reactions to produce the target molecules before time and fuel run out. Experiment carefully: unwanted reactions, unstable molecules, and evaporation can quickly ruin your brew.

This is currently a demo. If you wish this game to be developed further, let me know.

What’s Happening in the Cauldron ?

The Cauldron Challenge is driven by a tiny particle simulation. Every ingredient is made of moving particles with their own mass, size, and color. They fall under gravity, bounce against the cauldron walls, collide with each other, and can escape through the open top if the mixture gets too energetic.

Heating the cauldron changes particle motion when particles bounce from it. More heat means particles tend to leave the wall faster, so the mixture becomes more energetic and reactions become easier to trigger.

Reactions happen during particle collisions. When two compatible particles hit each other hard enough, part of their collision energy is considered usable reaction energy. If that usable energy passes the reaction’s activation threshold, the reaction has a chance to happen.

Molecule-forming reactions also need a nearby third particle. This third particle acts like an energy carrier: it helps take away the extra bond energy. This is why dense, well-mixed regions of the cauldron react better than isolated particles.

Molecules are still physical particles. They can collide, heat up internally, and eventually break apart if their internal energy reaches their bond energy. 

In order to produce the target particles, take the time to experiment with the particles and molecules to get a feel of their underlying properties !
