What earns a reward
One whole crystal at each friend level: 10, 20, 30, 40, 50, 60, 70, 80, 90 and 99. A new friend can earn you up to 10 crystals. Bank purchases, cards and friends of friends add no extra reward.
The player must be new
Your invitation must bring someone who does not already have a farm. They are linked to their first inviter. Inviting an existing player again does not create another referral reward.
Follow their progress
Tap your crystal balance to see invited friends, their progress, the next reward and your balance. Only whole crystals appear in the top bar and on guest visits.
Why shards matter
One crystal breaks into 75 shards. You need a reusable shop hammer or a Blacksmith’s Hammer from finds. Breaking is a separate, irreversible action: choose a number and confirm.
What you can buy
Crystals and shards cover eligible Stars-only purchases, such as licences, banking products and business equipment. They cannot buy ordinary coin-priced goods or coin packs. Level and other purchase requirements still apply.
Save or invest?
Whole crystals you hold contribute to the global ranking. Spending or breaking them changes that contribution at recalculation. Crystals cannot be exchanged for money or Stars, or withdrawn.
