Run a small experiment with two materials
Choose a small part of the canvas for an experiment rather than filling the whole scene. Build a simple stone container, then add a modest amount of a second material such as sand or water. Observe how the arrangement changes. Keeping the setup small makes it easier to connect a visible result with the stroke you just made, instead of trying to explain many simultaneous interactions.
Use Pause to inspect the scene or place material without the simulation immediately changing it, then resume to observe the result. Change only one feature in the next experiment: the shape of the container, the amount of material or the opening you leave. This is a sandbox investigation, so an interesting result need not be a win or a score. Describe what you see before assuming a physical rule that the current material combination has not demonstrated.
Distinguish an unwanted stroke from an unwanted experiment
If one paint stroke was misplaced, the Undo action can reverse a stroke. If the entire setup is no longer useful, Clear provides a fresh canvas. Read those actions as editing controls rather than assuming that Undo is a complete rewind of every simulation moment. For a repeatable comparison, start with the same simple container and change just the feature you want to investigate.
Keep notes in ordinary terms, such as where material collected or whether an opening changed its movement. You can return to the game page for the exact painting, pause and editing controls. Cozcade's edition is presented as a single-player browser sandbox; this guide does not promise community uploading, shared creations or a cloud gallery from another deployment of Sandspiel. The practice checklist belongs to the guide page and is separate from the canvas, its history and any locally stored game state.
For example, compare a closed stone container with a similar container that has one small opening. Add a small amount of water and watch where it collects. Start again with the same general shape if you want to compare an opening in a different position. Keep the change small enough to describe, and use Pause when inspecting the arrangement. The useful outcome is an observation tied to a setup: what you changed and what followed. A dramatic mixture of many materials may be entertaining, but it is harder to use as a focused comparison.

Sandspiel questions and answers
Is there a winning score?
The published sandbox is for creative experiments rather than a required score or level sequence.
Can I publish my scene to a gallery?
This adaptation is a single-player canvas sandbox. It does not offer the original project’s online community as a Cozcade feature.
Where is the source?
The adaptation is based on Max Bittker’s MIT-licensed Sandspiel project. The source and reviewed license links are below.
Can I build a container before the particles start moving?
Yes. Pause the simulation, paint the solid boundary, then add a small amount of material inside it. Painting still works while paused; Resume lets the particles interact again. Undo restores a drawing snapshot rather than rewinding every simulation step, so pausing first makes a controlled materials experiment easier to repeat.
