Building Tips

  • We advise to start with a structure made of triangles of the same shape and to use all available anchor points. 

  • Whenever possible lay part of the bridge on the ground, building a support structure that holds up the bridge.

  • Use anchor points on pylons as a starting point for cables. Cables are able to span a long distance and are great to sustain suspended bridge parts with weak support.

  • If the bridge should be spanning a large gap, you can build a second parallel row of triangles like this:

  • Another possible solution could be to build an arch bridge that is borne by the right and left banks. The advantage of the arch bridge is that the load is carried outward along the arch to the underside of the bridge, therefore it is necessary to construct strong foundations.

  • If the bridge still falls down, combine the techniques above to make it stronger.  
  • Try to construct symmetric structures so load will be better distributed along the bridge and weaker elements can be found more easily.
  • Remember that you can find out which elements are supporting more load, and thus will probably crack, using the stress option.

Good Work!

A few FAQs

- How it is possible to delete a piece?

Tap the delete button (in the top-right screen) to activate it, once enabled tap the elements you want to delete, then disable it tapping one of the elements selection buttons.

- How does undo button work?

The undo button (in the bottom-right screen) cancels the last action done to the drawing, that is it deletes the last created element or recreates the last deleted element.

- What does magnetic hook do?

The magnetic hook is a drawing option, you can enable it to facilitate attaching to existing anchor points when you draw a new element.

- Is level 12 missing an anchor point?

No, but it has a non-standard solution, instead of the last anchor point, there's an anchor point on top of the ending bank that allows the sustaining of the last road element.

- How can I improve my score?

You can specially improve it avoiding part breakages, minimizing the stress that the elements of the bridge suffer and using the fewest possible elements. Finally higher difficulty increases total score.
