Invite someone to begin, not just click
Crystals reward a new player’s progress. Your friend must create their first farm through your invitation. Clicking a link or inviting an existing farmer does not create a new reward.
Ten milestones for one friend
You receive one crystal at friend levels 10, 20, 30, 40, 50, 60, 70, 80, 90 and 99: up to 10 in total. Help them understand planting and orders, then follow their progress together. Purchases and friends of friends do not add rewards.
Do not break everything at once
Some purchases require shards. A hammer turns one crystal into 75 shards, but you cannot assemble it again. Check the price of what you want and break only the number you need. The hammer remains reusable.
Invest in your next chapter
Crystals can pay for eligible Stars-exclusive purchases, including licences and business equipment. Ordinary seeds and coin packs are not included. Think about which purchase unlocks the next activity you want to explore.
