Increase Your Score with Skip and Boost Features

Plates Across America®

With today's release, we've introduced a set of new features that really improve the game play. The screenshot at right shows a few of the new ones including "Welcome to" signs plus skip and boost tokens. If you are new to Plates Across America™ you can play a live demo here:

New Skip and Boost Features

The "skip" tokens allow you to exchange the word puzzle with another one without penalty. The boost token allows multiplying your reward for a correct answer, but beware, it will also multiply the penalty if you get it wrong.

New Achievement Badges

We have also rolled out a series of achievement recognition badges and a page where you can see all of the badges you have earned. A sample of one of these pages is below. We are really excited about the features in this new  release. We hope you can give Plates Across America® a try to see for yourself.

Mileage Signs in Plates Across America®

Plates Across America® with mileage sign

We release a minor update of Plates Across America® today which adds road mileage signs. On some of the longer routes, this helps break up the trip and give you a peek into the upcoming cities.

Frequency of Mileage Signs

We tried to make these to increase the sense of travel of the game without being a distraction. This is a balance in how frequently these signs should show up. We also did not want to manually generate these signs across all our routes, so we needed some sort of algorithm. We wondered if real civil engineers face a similar problems when they have to decide the signage to put on roads.

We settled on putting the first sign about 10 miles into the route and spacing them about every 30 miles. We think that provides a good distance between them and matches our intuition about what our real-world experiences have been on the road.

Which Cities to Show on Mileage Signs

After we decided where to place the signs, we approached the somewhat more complex decision about "what" should appear on the signs. Which cities warrant being on there and which ones do not? The size of the city certainly matters, but so does its proximity to the current location.  This initially seemed like it could get complicated with a lot of nuances and edge cases. In the end, we found something relatively simpler that seems to do a decent job of mimicking the real world.

We use a two pass solution, looking for major cities first, out to the fixed distance of 120 miles, and then filling in minor cities between the the current location and the first major city. A major city is defined as one that has a population over 250,000.  If there are no major cities in the next 120 miles, we simply take the next 3 largest cities to show.  Simple, but seems to be effective.
