Can't save up stones...

I'm a light spender who buys the Everyday Pass every month and currently have over 220,000 😊 The conclusion is to full combo HARD or higher difficulty songs in live shows. For difficulties yellow, red, and purple, if you think you can full combo a chart, please do your best to full combo it. By playing various songs, your rhythm game skills will improve, and you'll be able to full combo more difficult charts, making it fun to earn gems. Also, besides songs, don't forget to collect the gems you get from daily challenge lives and events (story, exchange shop). It's hard to earn gems if you play Project Sekai long-term. Honestly, even if you collect gems without missing any, you'll still be short on gems, and you won't be able to get limited-time 4-star cards unless you refrain from gacha. So, if you can refrain from gacha for a long time and don't pull frequently (prepared for pity), you can play without paying. However, if that's not the case, I think paying is essential.
