Rollproof — Random Table Stress-Test Studio

Your random table can look finished and still hide a dead result, a 37% outcome, or a loop that never resolves.

Rollproof is an offline stress-test studio for TTRPG and solo-RPG designers who publish weighted or nested random tables. Build a table network, choose its root, and get an immediate structural audit before the manuscript reaches players.

This is a diagnostic tool, not another random table generator.

What Rollproof detects

• Circular and missing table references
• Unreachable tables and zero-weight results
• Duplicate outcome wording
• Terminal outcomes that dominate more than 25% of root rolls
• Low outcome variety using normalized entropy
• Thin tables and roll chains that run too deep
• Exact terminal probabilities propagated through an acyclic table network

A complete repair workflow

1. Model your tables, weights, terminal outcomes, and nested targets
2. Read the signal map and fix critical loops or broken references first
3. Compare the exact distribution and normalized variety
4. Work through the prioritized repair queue
5. Print or save a clean proof report, then export the project as JSON

The included Ash Road Encounters example deliberately contains a circular dependency. Break the loop and watch Rollproof recalculate the full terminal distribution.

Local by design

• One self-contained HTML file
• No account, server, analytics, subscription, or remote dependency
• Auto-save when browser storage is available
• Safe JSON export/import and memory-only fallback
• Print-to-PDF proof report
• System-neutral and usable in a current desktop browser

Honest limits

Rollproof v1.0 models non-negative weights, terminal outcomes, and one-table targets. It does not interpret dice formula syntax, stateful generators, cards without replacement, conditional scripting, or the fictional quality of your writing. Exact distribution is withheld until circular dependencies are repaired. Human playtesting still matters.

Included

• Rollproof v1.0 offline app
• Complete fictional example
• README with a five-minute start and recovery guidance
• End-user license
