Welcome to Skeleton Code Machine
“Few blogs are writing about the ins and outs of game mechanics with as much creativity as Skeleton Code Machine. Straddling the worlds of board games and RPGs, the site regularly finds fresh ways of thinking about how games work, both in theory and on the table. At a time when blogging is starting to feel like a lost art, SCM has picked up the baton and run with it.” — Cardboard Edison, “Best Board Game Resources of 2025” 1/5/2026
“Hugely useful, thoughtful and well written resource for any aspiring - or experienced! - tabletop designers here. I link to one of these in basically every BoardGameWire newsletter, always super insightful stuff.” — BoardGameWire 12/8/2025
“There’s a reason SCM is in our regular rotation of sites we check when compiling #TuesdayNewsday each week.” — Armchair Dragoons 12/8/2025
Skeleton Code Machine is an ENNIE-nominated and CRIT award-winning weekly newsletter exploring tabletop game mechanisms — named one of the Best Board Game Resources of 2025 by Cardboard Edison.
Instead of focusing just on board games or roleplaying games, Skeleton Code Machine gives you tools and structures for thinking about and making tabletop games.

Get more inspiration with TUMULUS
TUMULUS is a print-only, quarterly compendium of analog gaming inspiration, tools, design theory, and playable content from the award-winning Skeleton Code Machine. Each printed issue explores a different theme, with articles, games, random tables, and game design exercises. It is available as a four-issue subscription or as individual back issues.
My vision for Tumulus is that it’s a print-only artifact that lasts a long time. So unfortunately it is not available as a digital PDF.
