Just in 5 days, the new KONAMI Yu-Gi-Oh! card battle game the Yu-Gi-Oh! Duel Links reached the 3 million downloads in Japan. (iOS and Android version together).
KONAMI going starts a maintenance today which going to ends on November 29 which means until that you can’t play with.

For the apologize and to celebrate the 3 million downloads you will get 200 gems and 30 gate-key BUT only if you installed and logged into the game on November 18, so the fresh new users can’t grab this huge amount of gems.
