Tough early game, but strong late game

The early game is tough because daily quests take a while to unlock and it's a long way until you can participate in events. You'll find situations with few people and few bingos, like 30 people for 10 bingos. As you progress, the numbers suddenly increase to 100 people and 50 bingos 🤔 At this point, use things like 4 Megas for experience and treasure chests, and also aim for bingo. If you get the Rainbow Star skill early on, it's recommended to wait a bit before using it. The reason is that if you use it after a few numbers that can be filled appear, it might coincidentally fill those numbers. This allows you to get a high rank, giving you spare blue coins. For other skills, it's better to use them immediately. The charger-type skill that becomes available with 2 skills is very valuable, so use it wisely.
