Dice is a popular game in which players make bets on the outcome of the dice-roll. Dice changed its form from game to another over the course of history but today it is commonly known as Craps. The whole game resides on the occurrence of a single number. So, when online Dice arenas were introduced in casinos the validity of dice came into question, i.e is the number randomly generated by the site is truly random or not. Also, it could not be verified by the player whether the game is fair or not i.e a game being hosted on a third-party server may communicate its data to other entities thus favoring a specific party in the game. So, there are few online casinos which offer dice.

The Game
The ethereum dice game operates on a smart contract specifically built for gambling with dice. It requires no deposits or signups. You can just use the game address to pay your way or play with credit.
The game involves players betting on the value of the dice either being in a pre-specified low or high range. If the number chosen by the player falls within a range low or high, he wins. The contract has a small waiting time which is meant to be the window in which the players place their bets. After that time duration expires, the smart contract requests a random number to be generated from an external resource. The smart contract tabulates results and identifies winning and losing players. Payments are paid out instantly once the random number is generated.
Provably Fair Dice
Ethereum makes sure that the random number being generated by the system is truly random. The smart contract does not use the blockchain to generate random numbers although generating number on the blockchain would be highly convenient. The reason being the fact that miners could manipulate the result by allocating and de-allocating specific blocks in pursuit of a favorable number. Thus, a third party is used for random number generation.
Usually, Random.org is used by most online Ethereum Dice sites. The smart contract ensures that the number has not been tampered with since its generation by using a tool called Oraclize.it. In case, the number returned by Ranom.org is invalid or it yields an error, the smart contract cancels the current game and all bets are refunded almost instantly.
Thus, Ethereum Dice is a basic online casino based on the Ethereum blockchain. The game is provably fair and relies on the Ethereum smart contract system. Playing a game doesn’t involves the hassle of registering, you can just sync to the latest ethereum block and either pay or play the game on credit bases. So, if you’re interested in gambling with Ethers then Ethereum Dice is a good way to go.
