Tools, Calculators & Guides
Plan before you build. Every tool here is interactive and free.
Density Calculator
Pick any mix of materials and instantly see the predicted settling order — heaviest at the bottom, lightest at the top. Includes builder notes.
Production Planner
Tell the planner what to produce and at what rate. Get back the full upstream chain — raw inputs, intermediate products, and building counts.
Research Tree
All 44 research nodes across 6 tiers with Gold costs, prerequisites, and a recommended unlock order. Filter by tier, kind, or priority.
Material Database
Every Sandustry material with density, matter type, source, processing, byproducts, and physical properties. Sort and filter to plan logistics.
Gold Factory Blueprint
Step-by-step automation walkthrough: Wet Sand → Shaker → Gold + Residue, plus the burn-Residue-for-bonus-Gold thermal loop.
Beginner Walkthrough
Phase-by-phase roadmap from your first shovel strike through early automation. Avoid water floods and sand clumping.
Fundamental Physical Laws of Sandustry
1. The Wet Sand Formula
HYDRAULICSDry sand cannot be sifted in Shakers. It must touch Liquid Water to trigger the physical transformation into Wet Sand.
2. Shaker Sifting & Residue Split
GRAVITY MESHFeeding Wet Sand into an Industrial Shaker drops pure Gold through the bottom mesh and pushes Slag horizontally.
3. Slag Thermal Reprocessor
PYROTECHNICSRoasting Slag with a Flamethrower creates Burnt Slag. Crushing it in a Kinetic Press reclaims extra gold and spores.
4. Launchers & Trajectory
KINETICSConveyors only move items horizontally. To lift materials against gravity, use submerged Launchers to shoot particles upward.
Frequently Asked Questions
Why is my Shaker clogging in Sandustry?
The primary cause of shaker jams is unevacuated Slag Residue. Shakers push slag out across the top deck much slower than gold drops through the bottom mesh. Connect an automated conveyor to the upper right outlet to keep throughput constant.
What is the settling order in Sandustry?
Settling order is the relative pixel density hierarchy that dictates which substances displace others when mixed. Gold has the highest density (#1), sinking below wet sand (#3), dry sand (#4), slag (#5), and water (#7).
Is there Steam Workshop mod support for Sandustry?
Yes, Lantto Games and Hooded Horse support official Steam Workshop integration for community maps, quality-of-life enhancements, and custom sandbox scenarios.
