Challenge

Open SpecFlag Sorting Game

A given sorting criterion alphabetical order used by default

16 flags randomly taken from a set of 38

Random positions in a 4x4 grid

A challenge tap the flags in the proper order in minimum time, according to the sorting criterion proposed

The first tap is always correct

The n-th tap is correct if the sorting parameter associated with the tapped flag is greater or equal than that associated with the last tapped one

At the n-th correct tap, number n is displayed near the tapped flag

At each tap, the value of the parameter associated with the tapped flag is displayed

A tap is wrong if it is not correct, i.e., if the value of the parameter associated with the tapped flag is less than the one associated with the last tapped flag

When a wrong flag is tapped, it simply disappears from the grid

Open SpecScore

Size of the search space

There are 16! (i.e., more than 1020) different ways of sorting 16 flags

The maximum achievable score is 16!

The first tap is always correct and sets the score to 1.

At the n-th correct tap the score is multiplied by n

To achieve the highest score, all the flags have to be tapped in the proper order in less than 1 minute

• 38 CodeWeekEU countries (28 EU countries + 10)

• 16 combinations of a given set of 38 flagsN1 = (38 choose 16) = 38!/(16!*22!) = 22,239,974,430

• Permutations of the 16 choosen flagsN2 = 16! = 20,922,789,888,000

• Number of different instances of the game:N1 x N2 = 465,322,312,113,382,000,000,000 = 4.65 x 1023

Open SpecChallenge

Incremental releaseAn application stub was released on the Google Play store

before the beginning of the actual development

A new (working) release was uploaded after each development step

End-users could both contribute to the development and watch the game take shape in their hands by installing updates on their smartphones

Live coding sessionsAi2 was used as a development platform

– Visual programming– Cloud-based environment– Android platform

Coding sessions streamed live step by step

Video logs available online together with project files
