Trussmere

Trussmere is a bridge-building physics puzzle over highland gaps. Join anchor points with road planks, wooden beams and steel cables while staying under budget, then press test: a cart drives across, every member shows its stress from green to red, and anything pushed past its limit snaps. Steel only pulls, wood pushes and pulls, and a deck that sags too far tips the cart into the mere. 12 gaps grow wider, add rock spires and towers, and later carry a hay wagon and a stone wagon. Stars reward money left over. It plays in the browser with a keyboard, mouse or touch.
