Thirty-One Games in a Single HTML File Each

Classics, original strategy, and engineer-built simulations.

Board Gaming Hub is the public home for every browser game I ship: Chess and Go beside original designs like Agora, Bisque, and Aresia, plus simulations that use real formulas — Floodline for California flood defense, Bonneville Spillway Operator for dam operations, Eclipse Predictor for solar eclipse paths on a 3D globe. Open a page, play immediately. No account, no installer, no ads on gameplay screens.

The games on this site are free and open source. They share a single rule: every equation inside has a real-world reference. Floodline scenarios trace real California events; the eclipse globe uses astronomy-engine ephemerides; Bonneville models spillway hydraulics and total dissolved gas. They are not research tools, but they are not toys either.

By day I’m a licensed Professional Engineer in dam safety, hydrology, and hydraulic modeling — HEC-RAS, SWMM, and emergency action plans for real dams in the Southeast. Nights and weekends I build software: engineering tools for peers, and simulation games when I want to think about something bigger than a single watershed.

HydroComplete

An integrated stormwater design platform.

Drag-and-drop BMP palette, real SWMM and TR-55 formulas, sediment and nutrient routing, USDA soil lookup, and a sediment model that actually routes water through thirty-plus BMPs. Built because the state of practice for small-site stormwater is either a four-thousand-dollar license or a spreadsheet, and I wanted something in between that didn’t cut corners.
