Frequently Asked Questions.

Q: When the game will be out?

A: Keep checking our homepage at

Q: How many NFTs will be available?

A: There'll be 1000 NFTs.

Q: What happens when my wagon gets destroyed?

A: Your wagon NFT will be burned.

Q: Can I buy more than one wagon?

A: Yes, you can. There's no limit to the number of wagons you can purchase.

Q: Can I sell my wagon NFT if it's in a vulnerable state?

A: No, you cannot sell, transfer or settle down a vulnerable wagon.

Q: Is there a limit to how many Extra Supplies I can buy?

A: No, there isn't a limit to it. However, the price will grow exponentially, so keep an eye on it.

Q: Is blockhash a secure source of randomness?

Solidity makes available the has of the 256 most recently mined Ethereum blocks. The blockhash is effectively unknowable to anyone ahead of time, even the person mining. When a person does successfully mine a block, they don’t have the power to change the blockhash without starting the mining process again, so unless they stand to lose millions of dollars from that particular blockhash, its unlikely they’d do so, because someone else will mine the block and get the block reward. What all this means is that blockhash, if used correctly, is a completely secure, unpredictable source of on-chain randomness.
The determinism of blockchain transactions do make on-chain randomness harder. If a tx depends on a certain random value, and that value is calculated during that tx, then it’s trivially easy to peak at the answer before you commit to the action.
However, using the blockhash of a specific block from some time in the past can’t be cheated, as long as the commitment to the result happened before that block.
An analogy would be if we were to bet on whether the temperature in my home town would be above or below 30°C (86°F) on Sunday. As long as we both commit our guesses before Sunday, and the winner can collect their prize from Monday, there’s no way to cheat. Before Sunday it was unknowable, and after Sunday it can’t be changed. (Meteorologists don’t @ me, to us mere mortals it’s all random).

Q: Do you require to be on the same trail to ambush vulnerable wagons?

A: No, you don't need to be on the same trail as the target wagon to ambush it. We decided to not constrain this mechanic to avoid undesired standoffs and keep wagons elimination a common event.

A: We can't help but quote the excellent explanation by @AnAllergyToAnalogy, creator of The Doomsday NFT, in his on Cryptostars.
