Recommended for point-earning, though the amount is small

Normally 160 yen (200 yen during a Warau bonus). This is an offer to reach level 14 within 3 days. You can achieve it in about an hour and a half. It's easy, so you should do it quickly before the offer disappears. *For those who know, 'airplane mode cheat' didn't work. ① EXP → ② Rarity → ③ Seed Planting → ④ Growth Speed. Watch ads in this order to level up. Repeat ③ and ④ before the time limit for ① and ② (either 5 or 10 minutes) runs out. The ads were about 30 seconds each. I didn't count, but I think I watched about 50 ads, and I managed to complete it in an hour and a half. When you harvest, you get boxes, and it's a small joy to win PayPay 1P by lottery (lol). I got a total of 6P. Development and shipping are not necessary for point-earning. Rarity increase (apparently) is irrelevant up to level 14.
