Test a load-bearing structure or a marble route

Construction here is a small, concrete planning task. Bridge Builder tests whether a truss carries a truck. Marble Run Builder tests whether rotated track pieces deliver a marble through every required pickup.

A triangle needs a connected path to the banks

Bridge Builder offers timber and steel across twelve fixed puzzles. Join bars into a continuous structure, then test with the truck. A strong isolated section cannot carry load to a bank. After a failure, adjust the same bridge while respecting the budget; a successful design can still be improved for lower cost.

The shortest exit is not enough

Marble Run Builder requires all three crystals before the bottom-right exit. Rotate tiles to join their openings, using locked tracks as anchors. The campaign has 24 levels and each run allows five launches. Test the route deliberately rather than spending a launch before checking every connection.
