More Information...

Crypto Kingdoms is a strategy game built on the Ethereum blockchain. Playing the game is a great way to learn about blockchain technology while having fun playing a game.

The MetaMask Chrome extension (or mobile apps) will allow you to create an Ethereum wallet that will hold an Ethereum address that can be used to transfer Ethereum to and from any other Ethereum address. It also enables browsing of Ethereum-enabled websites such as Crypto Kingdoms which uses an Ethereum smart contract to host a multiplayer strategy game with a prize!

You don't have to spend any real Ethereum to play the game - just switch your MetaMask extension or browser app to the Ropsten test network, request some free test Ethereum and join us on the test game! But first, get the Ethereum browser extension or mobile app from one of the links above!

On the Ropsten test network you can get free test Ethereum from the Ethereum Ropsten Faucet website.

New Kingdom Name:

It costs {{ Math.ceil((gameValues.gameJoinCostEther + gameValues.gameJoinTransactionCostEther) * 1000) / 1000 }} Ethereum (also called Ether or Eth) to join the game which pays for the prize pool and the game host's fees. Actions within the game have small transaction fees (average cost of {{ gameValues.averageTransactionCost }} Eth, which goes to Ethereum miners). The game will require at most {{ gameStats.gameTurns - 1}} actions to secure a victory, so it will cost {{ Math.floor((gameValues.gameJoinCostEther + gameValues.gameJoinTransactionCostEther + gameValues.averageTransactionCost * (gameStats.gameTurns - 1)) * 1000) / 1000 }} Eth to play a full game in total.

Attack ⚔️ Send in your army to attack another player's kingdom and try to steal some of their gold! ⚔️ An attack power is calculated based on the amount of soldiers you choose to send plus the number of spies, wizards, and dragons in your kingdom. A defence power is calculated for the defending kingdom as the attack power for its army plus the defence power of its barracks and castles. If your attack power is greater than your opponent's defence power, you will win the attack and take a fraction of your opponent's gold! Soldiers, wizards, and dragons may be lost on both sides during the battle. Only the attacker's losses are reported in the public event log. 💀 (Gold taken is proportional to the closeness of the battle. If the battle is close, huge casualties and large portions of gold may be taken.)
Espionage 🔎 Costs {{ formatThousands(gameValues.espionageCost) }} gold. Contract your spies to discover information about another player's kingdom! 👀 If you have more than half the number of spies your opponent has, everyone will receive a piece of information about your opponent's kingdom in the public event log. Using espionage does not use an action.
Sabotage 🔥 Send in your trained dragons to destroy a fraction of an enemy's kingdom! 🐲 If you have more dragons than your opponent has castles plus dragons, some of your opponent's mining camps, banks, and hovels may be burned to the ground. Dragons may be lost on both sides during a sabotage.
