To commemorate the second anniversary of the "Blue Archive," a stamp rally to solve riddles around Akihabara, "Blue Archive -Code Trick Challenge-" is being held from February 1 to March 5, 2012!

To commemorate the second anniversary of the "Blue Archive," a stamp rally to solve riddles in Akihabara and other locations is being held from February 1 (Wed.) to March 5 (Sun.).

In the ongoing stamp rally "Blue Archive ~Code Trick Challenge Letter~," visitors can obtain a pamphlet at each of the participating stores, scan the 2D barcode on the character panel, and collect stamps to obtain clues to solve the riddle. The collected hints can be used to solve the code and obtain in-game items. The hints and answers to the riddles can be shared with others.

The serial code will be an 11-digit capital alphabet.
The hints and answers to the riddles can be shared!

In addition, a campaign is underway at participating stores listed in the pamphlet, where an original novelty card (28 types in total) will be randomly given away for every 500 yen spent. (*The maximum number of cards distributed per bill is 4.)
Also, by going to the participating stores and scanning the 2D barcode on the character panel, you can get a stamp, and after you have collected all 16 stamps, you can get the limited-edition goods as a reward at "Animate Akihabara".
