Terraforming Mars Player Board

A dual-layer 3D-printed player board for Terraforming Mars with recessed tracks that physically hold your resource and production cubes in place.

Ask any Terraforming Mars player about their worst gaming memory and you'll hear the same story: two hours of engine building erased by one bumped table. The stock thin boards make cube-slide inevitable; this dual-layer board makes it impossible. Production stays set between generations, resources survive an excited gesture, and the game's biggest practical flaw disappears. This is the most-requested upgrade in the hobby for a reason — for TM's long sessions, it's not a luxury, it's insurance.
