Engineer on a budget
Bridge Builder.
Fifteen river gaps, one budget each. Lay road, brace it with wood and steel trusses, then send the truck across and watch every beam glow green, yellow or red until it holds or snaps into the river.

How to play
Bridge Builder
Build a bridge strong enough for the truck to cross, while staying under budget.
- Drag beams between joints. Start on a joint or a red anchor.
- Gray road beams carry the truck. Wood and steel hold the road up.
- Triangles make the bridge stronger. Stay under the budget.
- Press Go and watch the truck cross. Red beams show weak spots to fix.
