Product Features

  • Based on civil engineering principles and physics
  • 25 puzzle levels and 11 free build levels to choose from
  • Free build mode features an unlimited amount of building materials
  • A variety of real-world bridge building materials to use
  • Adjustable train weights increase difficulty levels

Product Description

Build bridges, not walls, with X Construction loaded on your Android (OS 2.1 or higher), and then send a train across your creation to see if it holds up under the pressure, or collapses into catastrophe. Representing a real-world twist on the addictive physics-based casual game genre, X Construction uses the materials and building principles of civil engineering as you try out new bridge designs and test their strength with fully loaded trains.

X Construction
Start at the base points and drag girders to build the bridge

For each of the 25 Crossing levels, you'll be given a limited amount of supplies to build your bridge, and a limited number of foundation base-points to use as structural anchors. As you lay the girders, concrete and cables down with a touch and drag of your fingertip, you have control over the material's length, to a point. And this is where the puzzling, exciting aspect of the game comes into play: simply placing girders in a random but eye-pleasing manner will likely result in a literal train wreck of a project.

Dream, Build, and Improve

Additionally, 11 Free Build Sandbox levels give you the freedom to use as much building material as you feel you need. It's the perfect way to try out new designs before taking them to the Crossing levels, which unlock progressively with each successful bridge built and tested.

If you run out of building materials, but you've spotted what you feel is a flaw in your design, select the undo-arrow to remove your last piece. Zoom in and out with the plus and minus magnifying-glass icons to aid your manipulation and final placement of the building materials. For a more precise approach, select the steel-worker's wrench, tap the object you want to remove, and then select the I-beam icon to place it in a new location.

Engineering Tips

If you've ever picked up a hammer, some boards, and a handful of nails to make something functional, whether it's a simple table or a complicated tree house, you know that making something safe, sturdy and functional is harder than it looks. X Construction is no different, but fortunately the app features several innovative ways of guiding you through the process of making a solid bridge without just taking over and doing it for you.

X Construction
Building haphazardly will result in disaster!

If you're stuck in a crossing level and your build is continually failing, select your smartphone's menu button to access the help option for engineering advice regarding the specific materials your level is using. It's the games most straight forward way to lend you tips to help you improve your designs. For example, "Concrete endures pressure easily, but breaks under tension. Note also that it is very heavy."

A more subtle and enlightening approach is to dive into X Construction's preferences level and check the Show Stress box. This will tint the specific parts of your bridge in varying degrees of red when they come under stress. Take note of the stress indicators when you send trains across the gaps, gorges and rivers, even if your build succeeds. This visual feedback will guide you, through trial and error, to have the simulation show as little stress as possible, thereby improving your overall skill in the game.

5.0 out of 5 stars Deceivingly simple April 10, 2011
By Bic
Excellent game. The physics are a bit dubious, but seem a reasonable approximation. Some of the solutions remind me of the wonky third world bridges I've seen.

And as a bridge builder myself, I find I have to throw out a lot of "tried and true" principles to "beat" this game.

Love the screams when you fail. Wish there was an optimal solution cheat sheet to see the most efficient, or unusual solutions.

5.0 out of 5 stars If you liked Spaghetti and Marshmallows... April 9, 2011
By Lee
Verified Purchase
This is a slightly more 'serious' building app than Spaghetti and Marshmallows. Here, you'll build, test, and build again to compensate for those vexing structural failures that culminate in screaming train wrecks. It's wonderful for demonstrating engineering principles to younger audiences and keeping you entertained for quick bouts of boredom. Your bridges save after you've exited the game, so if you have to take a break, your work will persist.

The younger players I've showed this to tend to respond most enthusiastically to the results of poor construction, but you'll feel the tension as the moment of truth approaches and the train rumbles toward the critical point -- will it hold, or will it fail? And as the surface buckles under the load, you can see the disappointment and the resolve to build it better, to take the failure into account -- or the collective sigh of relief at the bridge holding fast.

When I see a particularly decent design that falls apart due to small oversights, I imagine Henry Petroski lecturing on engineering failures in the background -- for readers who don't get bored by talk of bridge failure analysis, this is a fun little building game. And for the rest of us, it's a nice lesson in armchair engineering.

5.0 out of 5 stars Very, Very great game March 25, 2011
By Danny
I got the game from the Android Market, but I wanted to review it on here anyways just to support a great game. This game makes you think out what you have to do, has great and colorful animations, and, this is my favorite, give you a giggle or two every time the passengers of the train scream for their live as they are falling of the cliff.

3.0 out of 5 stars Lacks Content April 10, 2011
For an app that is not free, you expect to be entertained for a decent amount of time. This app contains only 15 puzzle levels, each of which can be beaten in 5 minutes for the average person. While it does contain 7 sandbox levels, you can easily become bored with them in short time. The graphics are also subpar when viewed on a tablet, and appear stretched and fuzzy.

5.0 out of 5 stars Fun Game. April 9, 2011
Verified Purchase
I've had this game on my tablet for a while, but never got around to downloading it to my phone until I noticed it was the App of the Day.

I have to say this is a really great physics based game. I really enjoy building the bridges...but honestly, what I enjoy even more are the screams of the passengers as the train plummets to it's demise. I think it's hilarious in a demented and twisted way. Whenever I fail, I don't get upset because I just get to listen to the hilarious sound effects.

Overall, this is a must have game if you're an Android owner looking for games.

Great stuff.

5.0 out of 5 stars Lots of fun April 5, 2011
By gboi
Makes you think and have a lot of fun along the way. The physics seem realistic. I like to solve the puzzles when limited pieces are available, but my favorite is sandbox mode where you're allowed unlimited parts. I very highly recommend this.

2.0 out of 5 stars Not ready for prime time April 9, 2011
I played the demo of this a while back and thought it needed work before i would buy it. After playing the full version, I'm glad I never bought it. The interface is horrendous. it needs a zoom window badly because your finger blocks all the action. There are other frustrating issues as well.

2.0 out of 5 stars Too hard April 9, 2011
Verified Purchase
The interface is okay but this is very difficult. A tutorial for people who aren't natural engineers would make a big difference. Just saying that triangles are more stable isn't all that helpful.

Great game, sadistic sound effects make it clear that others hurt when your structure fails. keep retrying to shore up the weak parts until the train(s) get accross.

higher levels use concrete piers but doesn't explain how they work/ advantages. Lower levels are fun though, can't really recommend.

Figure out the architecture needed to support a bridge in several situations. Great time killer, and bathroom recommended! Watch out, addicting as Angry Birds!

This is a great game to play when you have lots of time to spend or just a few minutes. It will not loose your creative bridge construction (or any progress) when you close it. Read more
