MegaCryptoPolis is a decentralized city builder game running on Ethereum blockchain smart contracts that you can play in any browser or on mobile device using special apps.
Every building in this a game is a crypto token which ownership rigts are verified in the blockchain.
Please use Ethereum digital wallet like MetaMask, Trust or Coinbase Wallet allows to create an account and authorize in MegaCryptoPolis. Every action in the game is a transaction on Ethereum smart contract that requires a signature in your digital wallet. You may need some Ether on your digital wallet to pay for gas and send transactions.
Ethereum is an open-source, public, blockchain-based distributed computing platform featuring smart contract functionality.
Ether – is Ethereum blockchain cruptocurrency that is used to pay for gas, run transactions on smart contracts, can be easily transfer between Ethereum wallets and exchanged to other cryptocurrencies.
Transaction requires Gas in order to be stored in Ethereum blockchain. It is an execution fee paid for block miners to include information about transaction in the block on Ethereum network. Its price is expressed in Ether and depends on current blockchain load. Miners may refuse to process transaction with less than a certain asked gas price — that may be the reason of failed or delayed transactions.
Gas price is set in Gwei that is 1/1000000000 part of Ether (1 Gwie = 0.000000001 Ether). Safe low gas price is normally 2-8 Gwei, though it may reach 20-30 Gwei when network is congested.
Gas price can be adjusted in a digital wallet interface while sending a transaction:
Setting a low gas price may result in freezing your wallet — new transactions will not succeed if there is at least one pending transaction.
There are several ways you can refill your MetaMask digital wallet balance:
1. Buy Ether (ETH) using your credit card services like Coinbase, Coinmama, CEX, Coinhouse or LocalEthereum.
2. Exchange Bitcoin or any other cryptocurrency to Ether on ShapeShift or any crypto exchange like BitFinex, Kraken or Poloniex.
3. Send Ether from other wallet to your MetaMask (Trust or Coinbase Wallet Wallet) address.
You can find your MetaMask Ethereum wallet address by clicking on the icon next to your account address and selecting “Copy Address to clipboard”:
You can receive Ether before the actual game launch (on “Lands Preorder” stage):
1. Acquiring a land block in MegaCryptoPolis grants you part of Ether spent by other players to acquire nearby located land blocks in a 7x7 field.
2. Being a district owner also grants you a part of Ether spent by players to acquire land bocks in this District. You can set the price for blocks (from 0% to 100% increase) that defines your income.
After the game starts, in addition to abovementioned:
1. Buildings constructed on your land blocks start to generate influence points those can be collected and then converted to Ether.
2. Being a district owner also grants you a part of taxes paid by players from every action in your region.
Ether transferred directly to your Ethetreum wallet that you use to play the game.
MegaCryptoPolis game may show you a lock screen from time to time. This happens because MetaMask automatically locks your account after a certain period of time. To unlock you wallet please click on the MetaMask extension and type in your password.
At the moment there is no cold (offline/hardware) wallets with support of ERC-721 tokens and ability to sign you on the website. Please use MetaMask, Trust or Coinbase Wallet digital wallets to play the game and store your game assets.

A block of land is minimal requirement to start playing the game that allows you to construct and upgrade a building to gain influence points and collect your share of taxes.
Owning several blocks of land situated near each other allows you to build a Mega Building that will have a multiplier for influence scores after the game starts.
Block price depends on its location and the number of blocks sold around it. Every time someone purchases a land block it rises prices of blocks in 7x7 field around it and transfers part of its price to neighbours.
Prices for spare land blocks are growing as others purchase neighbouring blocks, price for each block of land is calculated on the blockchain, everything is truly decentralized and there is no way to predict who will buy where.
Block price rises with every next block sold in 7x7 field around it. The initial block price may vary from 0.01 to 0.02 ETH. In average, all the blocks sold within 7x7 area (in an abstract field without any roads and parks) the price of the last block will be 100 ETH.
Yes, you will get part of new block price back to your wallet that actually means you will have kind of a discount for the price of the new block.
Yes, you will receive Ether from sales of blocks in neighboring districts after they will be opened within 7x7 area.
If the land on the other side of the road is still in your 7x7 field, you will get your part of Ehter as usual.
Please wait until next district auction will finish and it’s land blocks will become available for purchase.
Yes, you can sell your block of land after the game starts, even if there are no buildings constructed.
Yes, total number of land blocks is limited as shown on the game map ― there will be no new blocks or new districts added, ever.
All spare blocks will be available for sale on the same conditions after the game starts.
Please enter the game and click on your district in auctions list – you will be able to set the price increase that may range from 0% (0.01 ETH initial blocks price and zero revenue for the district owner) to 100% (0.02 ETH initial blocks price and maximum revenue for the district owner).
The first district owner gained more than 25 ETH within the 1st two weeks after sales opened (with only 50% land blocks sold at that moment). Initial block price was set to 0.015 ETH (50% price increase). There is also an opportunity to get more Ether after the game starts (district owner receives part of every player’s action tax).
District owner has 24 hours after the auction ends and winner announced to set the initial block price and make all the district’s blocks available for sale. If district owner does not set an initial price within 24 hours, acquired district will be opens with default 10% price increase (0.011 ETH for initial block price). District owner can change this value any time even after the start of sales.
Yes, purchasing a block will have an impact on all the neighboring blocks in 7x7 area regardless the district borders.
Yes, there may be a slight delay after the region is sold and before blocks became available for sale. Technically we need to add them on blockchain, that requires max. 24 hours.
District open date will be prolonged for 7 days after the moment the new bid is made.
MegaCryptoPolis will give away 2000 blocks of land on the special Bounty Island (South East of the city map) for the help to distribute the word about the project.
Bounty rewards will be distributed randomly amongst all the enlisted participants of MegaCryptoPolis Bounty Campaign. Participating in special activities (like sharing information in social networks and joining our community) increases chance to get valuable block of land.
Use your rewarded block of land to play the game (build, upgrade and collect influence points) or just sell it on the market after the game starts.
Winners will be defined randomly. The more Scores you have gained during the Bounty Campaign the more chances you have to receive a block of land. Every additional Score on you account is your additional chance to receive a crypto land token.
All bounty land tokens will be minted and transferred directly to MegaCryptoPolis Bounty Campaign participant’s wallets prior to the game launch.
There may be several blocks credited to your wallet depending on overall amount of Scores.
The only way to make transactions faster is put higher gas price (please refer to "Gas?" and "How to set a gas price?"). That is how Ethereum blockchain is governed, MegaCryptoPolis has nothing to do with that, unfortunately.
All the game assets are stored in the form of ERC-721 tokens within your digital wallet. They may be not visible in the wallet interface though (as MetaMask does not support ERc-721 tokens). In order to check your assets please enter the game and click on the "My Blocks" icon - all blocks of land owned by you will be highlighted on the map.
Instead of Failing the transaction, MegaCryptoPolis smart contract just returns you Ether in case you have not succeed to purchase a land block (most common reason is that can happen due to some block sold around before your transaction got minted). That allows to save your Ether as the failing transaction also requires gas (much more gas in fact). Please take a closer look in your transaction at Etherscan – that will show you that Ether was returned back to your wallet. You can also track this from your wallet in Internal Transactions list in Etherscan.
We recognize the main aim of the game is to educate on how to use a cryptocurrency in a funny way in the form of entertainment. We believe that building the decentralized mega city on Ethereum blockchain will shape the way on how the blockchain games will look like in near future.
Most common reason is that someone had bought a block of land in a 7x7 area before your transaction was minted — that rised the price of your block and smart contract did not accept your transaction. That may happen due to higher gas price set by another player.
Your e-mail address is used to deliver you notifications about game progress like receiving an Ether from the block sold nearby or to inform you about new bids on the auction you are participating in.
All data is stored on Ethereum blockchain, MegaCryptoPolis game is just a GUI (graphic user interface) client hosted on a dedicated server that allows convenient management of your crypto game asses. Soon after game launch there will be a downloadable client for your platform to make sure you will always have a direct access to your assets via game GUI.
Please open MegaCryptoPolis game on desktop to highlight the district on the map. Mobile interface may not show this due to limits of the screen size.
