Shop and prices

Everything in the game is bought with CROWN. The price itself is fixed in GRAM and converted to CROWN at the current market rate, refreshed once a minute.

What that means in practice. The money value of an item never changes. If CROWN goes up, the same item costs fewer tokens; if it goes down, more. Until the token is listed the rate equals the presale price: 1 GRAM = 100 CROWN, which is what every number below uses. The live rate is always shown in the shop header.

Why the game costs more than the presale. We promised items would double in price after the presale and we keep it: a ×2 markup on the presale price. The bronze drill cost 1 GRAM, in the game it costs 200 CROWN, the same 2 GRAM at the current rate.

Price in CROWN = price in GRAM × 100 (markup) × rate (2 CROWN per GRAM)

Where the spent CROWN goes

Half of everything spent inside the game is burned forever, the other half goes to the platform budget.

How it will work after listing. GRAM becomes a way to top up rather than a separate purchase currency: the player pays from their wallet, the platform buys CROWN for that amount on the market and credits it to their game balance, and the purchase then spends CROWN. Until the token is listed there is nothing to buy it on, so bundles are still paid in GRAM directly. Everything else in the game is already priced and paid in CROWN.

Buildings are priced per level

The presale sold the first level of a building for GRAM. In the game buildings are bought and upgraded for CROWN, and the next level costs the base price × level number: mine shaft 100, 200, 300 and so on, smeltery 300, 600, 900.

A bundle is cheaper than the same items separately, and you only pay for what you do not own yet.

Referrals

Referrals are paid on purchases made in GRAM, because that is where real money comes in:

A bundle in the game. Your invitee paid for a bundle from their wallet — you get 10% in GRAM straight to your wallet.
The token presale. Your invitee bought tCROWN — you get 5% in tokens on your presale balance.

Purchases made with CROWN inside the game pay no referral: that CROWN was mined in the shaft and never leaves the game, so there is nothing to split.
