Score Day! was a series of time-limited events that occured on weekdays in the last two weeks of October 2015. Each day, a short event required the players to reach a certain score that started at 11 a.m. (GMT+9) and expired after 24 hours (11 a.m. the next day). A new short event playing with a different episode appeared on the next day.
The first Score Day! appeared on 19-23 October 2015. The same exact event appears again 26-30 October 2015.
