Just use Indonesian, okay? It's giving me a headache.
So, while the 3x Event is currently running, you can put Dimas Kanjeng's knowledge to good use. You can use 2x 1-day boosters from the attendance bonus. Or, if you have enough cash, you can buy 3x 3-day boosters in the Item Shop.
How to use it...
Don't use it right away.
Don't accept your friends' votes right away. Wait, collect them all first, like this...
(that's an example on a normal day if you have 70 friends and they all send 3x votes)
So, tonight, approaching the new day (10:00 PM WIB), you can use the booster. Your friends' votes throughout the day will be doubled that very second. The booster is still valid for the next 24 hours, as it was just activated (for the 1-day booster, the 3-day booster is valid for the next 72 hours). Essentially, one item can boost for one day plus an extra one for the next day.
So, if you want to use a 1-day booster during the 3x Event (which lasts 4 days), just use two items on the evening of days 1 and 3 (don't extend them) to save money and optimize your results.
Likewise, the 3-day booster can last for 4 full days, as long as you click "use" on the evening of the 1st day after all the submitted votes have been collected.
