How It Works

One round of Slot consists of 100 entries to the Slot smart contract, each costing 0.1 ETH. Once 100 contributions have been recieved, the smart contract randomly allocates prizes to 8 of the contributors and sends it directly to the samr Ethereum wallet from which the contirbution arrived. The prizes that are guaranteed are as follows:

Additionally, 0.25 ETH from every game remains in the jackpot pool and every spin can trigger the jackpot at 999,999/1, Whereas the 10ETH’sweepstake’ is triggered automatically every 100 entries, the progressive jackpot is triggered seperately using a random number generator.

As the results of Slot all take place on one smart contract, any player can verify the payouts using Etherscan. Winners will have their Ether credited almost instantaneously and be able to verify their win in their own wallet and on any blockchain explorer.

The source code is available for collaboration at GitHub and licensed under MIT. Although many forks of the smart-contract are expected, all the fun is here.

The odds are known beforehand and all the lots are automatically drawn in a decentralized and transparent way. The winner is selected by the Ethereum Block’s Hash, scrambled with SHA3 encryption, and is impossible to predict at the time of betting.

The results are publicly visible and auditable by Blockchain explorers such as EtherScan.io and Ethplorer.io. Furthermore, nobody can tamper with the funds, the code, or the settings, not even us. That means that the lots smart-contract will stand unchanged for as long as Ethereum exists.

The odds are set beforehand and 8 out of 100 players will see a significant return on their investment. That’s the fairest gamble in the cryptocurrency market and is bubble resistant.

Technical Details

how we guarantee the fair play

Slot is an Ethereum Smart-Contract written in Solidity. Users send 0.1 Ether to buy one ticket. A transaction with a lower amount won't succeed. If a user sends enough for multiple tickets, she will have more entries and a bigger chance to win. 

If the lot is full (i.e. 100 tickets have been sold), the user's multiple tickets will be split among two games. If the extra amount is not enough for another ticket, he will be refunded. After 100 entries -or 10 Ether- the sweepstakes are activated and the prizes are awarded based on a single pseudorandom number.

  The winning number will be the index in the participant's list by order of participation, and will receive the first prize. The second-place winner is the next to participate after him, and so forth for all prizes.  Furthermore, every user has a chance of one in a million to win the Jackpot, which is an accumulated sum from all games.

The winning number is based on the last block's hash. It is unknowable at the time of participating. This is because no randomness can occur within the Blockchain, since two differing blocks with different random numbers cannot achieve consensus. 

Gas

At the end of the sweepstakes, 0.249 Ether is set aside for the Jackpot, 0.249 for marketing and development costs, and 0.02 is given to the 100th participant to refund his Gas cost.

Gas prices depend on the number of tickets bought and whether the player is the last participant in the game. Approximately, the cost of participating is 68,000 Gas. Any extra ticket bought in a single transaction requires an extra 30,000 Gas (approximate). If the user is the last participant in a game (and activates the sweepstakes and award transfers), he needs another 130,000 Gas which is refunded after the game. Furthermore, the first player ever needs to pay an extra 20,000 Gas (approximate). For this reason, we recommend all players to include 300,000 Gas or more for any transaction, since Ethereum immediately refunds any extra Gas.
