The Powder Toy

How to play

1. Choose an element and draw it into the simulation; materials move and react according to their properties.
2. Pause, erase, adjust the brush and combine elements to build a small experiment.
3. There is no fixed level or score. Save sharing and account features belong to The Powder Toy host.

Make your move

• Mouse: left-click draws, right-click erases and the wheel changes brush size.
• Keyboard: Space pauses or resumes the simulation.
• This official web build opens on the project's host. Denny Games has not verified its save flow or device behavior.

A small head start

• Start with a few materials and observe what happens at their boundaries.
• Pause before adjusting a busy scene so you can inspect each interaction.
• The host's community saves and account rules are separate from Denny Games.
