Smart contracts – Ethereum network technology allowing automatization of obligations implementation and making the mechanism of interaction between people and programs transparent. Implementation of obligations stored in the smart contract code is guaranteed by Ethereum structure and mechanisms.
The results of interaction between the smart contract and people are permanently stored in Ethereum blockchain, being always available for inspection and control, and cannot be deleted or modified later providing the unique opportunities for organizing efficient work of a great number of socio-economic systems.
We have developed and launched the prototype of «European Roulette» game based on Ethereum smart contract. We did our best to make the game extremely functional and complete by offering:
To start playing it is necessary to install Metamask extension for Google Chrome browser. It allows organizing interaction between the client browser, Ethereum network and our smart contract via SmartRoulette.io interface.
The game is available both in Ethereum main network (Mainnet) and test network (Testnet). After signing up in Metamask the user may select Testnet mode and get several free ETH coins for testing the game.
Basic mathematical advantage over a player (House Edge) is equal to 2.7%. This parameter calculation is generally accessible and can be easily checked by everybody, for example, in Wikipedia. Thus, no matter how perfect the player’s game is and what strategies are used, the roulette is always in plus by 2.7% if analyzing quite long sequence of games.
Roulette’s effective work without house edge is impossible as it is this number that excludes any misuse and bankruptcy.
We are the team of developers and blockchain-enthusiasts with work experience of more than 4 years.
Smart contracts concept itself represents minimization of human resources involvement what we are trying to prove in practice. Trust the code and real numbers, not authors’ authority or advertisement.
We are sure that Satoshi Nakamoto’s anonymity didn’t prevent, but helped Bitcoin’s spread. In the country of developers team the legal status of cryptocurrency is still questionable and casinos cannot operate outside the allowed zone. In this regard we are not planning to reveal the personal data of the project founders and testers in the nearest time. However, after settling all the legal issues we don’t exclude the probability of public promotion of the project on our behalf.
Our nearest development plans involving our personal funds and primary investments:
Further development roadmap, goals and tasks are described in p. «ICO (Crowdsale)».
Name: Roulette token (RLT).
Initial amount: 10 000 000 (10 million).
Initial price 1 RLT = 0.0015 ETH.
Token standard: ERC20.
RLT tokens can be easily transferred between all the participants using Ethereum network addresses. Besides, tokens can be transferred into accounts on cryptocurrency exchanges and back after introduction of token support to the stock market.
There are several ways to get tokens:
RLT token liquidity is primarily backed up by our product and our main product are games. Therefore, to maintain tokens economic sense and attractiveness we bind the volume of the issue to the quantity and the volume of games played.
RLT tokens are generated after a bet is placed in any version of Roulette. Tokens generation is guided by the following formula:
Bounty = Bet * coef / RLT rate, where:
Bounty (in RLT) – new generated tokens received by players after placing a bet giving them the possibility to become a co-owner of the project;
Bet (in ETH) – a player’s bet size;
coef – the coefficient of return received by a player after placing a bet. This number is defined by the administrator and comprises:
Test period 03/14/2017 - 03/21/2017 | 3% |
Test period 03/22/2017 - 03/29/2017 | 2.5% |
Test period 03/30/2017 - 04/06/2017 | 2% |
Test period 04/07/2017 - 04/14/2017 | 1.5% |
after 04/15/2017 | 0.5% |
RLT rate – the current RLT token rate to ETH on crypto currency exchanges. The initial price of the token is 0.0015 ETH.
Besides, after launching the affiliate program we are going to issue additional tokens that will be generated together with placing a bet for payouts of rewards to affiliates. Emission quantity will be calculated according to the same formula with the coefficient of 0.1 - 0.5%. (p. «Affiliate program»)
RLT token holders have no reasons to worry that additional emission will reduce their share in the project and decrease the amount of dividends since:
At the same time players receive instant guaranteed bonuses in RLT tokens backed up by ETH cryptocurrency at the current rate and automatically become the game platform’s co-owners. All that leads to increasing players’ interest and popularity of the project.
Here we provide several examples to understand system work algorithm*:
03/17/2017
Basic coefficient 3%
Affiliate program is not launched yet
Rate 1 RLT = 0.0015 ETH
A player places a bet 0.5 ETH. According to the formula smart contract will issue 0.5 * 0.03 / 0.0015 = 10 RLT and send them to player’s balance.
04/05/2017
Basic coefficient 2%
Affiliate program is not launched yet
Rate 1 RLT = 0.004 ETH
A player places a bet 0.5 ETH. According to the formula smart contract will issue 0.5 * 0.02 / 0.004 = 2.5 RLT and send them to player’s balance.
04/17/2017
Basic coefficient 0.5%
Affiliate program coefficient 0.3%
Rate 1 RLT = 0.011 ETH
A player places a bet 0.5 ETH. According to the formula smart contract will issue 0.5 * 0.005 / 0.011 = 0.227 RLT and send them to players’ balance. Besides, if this player was rederred by an affiliate, the smart contract will issue 0.5 * 0.003 / 0.011 = 0.136 RLT and send them to the affiliate’s balance.
* - definite numbers are shown only to demonstrate calculations algorithm and may differ in reality.
100% of the profit gained from all the versions of «Roulette» (available now and being developed in future by SmartPlay.tech team) are distributed among all RLT token holders whose amount of tokens is sufficient for participation in profit distribution.
Initial amount of tokens necessary for participation in profit distribution is 1 000 RLT. In the course of the project development this number will gradually decrease.
This limit is connected with smart contracts work peculiarity, as transaction fee for payout of smaller amounts of dividends may exceed dividends themselves.
Once a day at 12:00 GMT the game smart contract checks the balance. If ETH sum stored in it is sufficient for paying dividends, the funds are automatically sent to the distributing smart contract.
The initial amount of the funds necessary for distribution is 50 ETH. In the course of the project development this number will gradually increase.
As soon as the smart contract responsible for the distribution of dividends receives ETH, it creates the list of all the users whose amount of RLT tokens is sufficient for receiving dividends. After that it calculates the sum of tokens owned by these users and processes payouts in proportion to the share of this amount.
Dividends are paid to Ethereum accounts belonging to these particular RLT token holders.
Here we provide several examples to understand system work algorithm*:
The user has 2 000 RLT
Token price at ICO rate 2 000 * 0.0015 = 3 ETH
The sum of tokens owned by distribution participants 9 500 000 RLT
The game’s profit distributed: 50 ETH
User’s dividends: 50 * 2 000 / 9 500 000 = 0.0105 ETH
The user has 50 000 RLT
Token price at ICO rate 50 000 * 0.0015 = 75 ETH
The sum of tokens owned by distribution participants: 9 800 000 RLT
The game’s profit distributed: 50 ETH
User’s dividends: 50 * 50 000 / 9 800 000 = 0.2551 ETH
The user has 800 RLT
Token price at ICO rate 800 * 0.0015 = 1.2 ETH
The sum of tokens owned by distribution participants: 9 800 000 RLT
The game’s profit distributed: 50 ETH
The user won’t get dividends since one’s balance is less than 1 000 RLT necessary for participation in dividends distribution.
* - definite numbers are shown only to demonstrate calculations algorithm and may differ in reality.
The main reward system for players is RLT token payout for each bet.
After placing a bet a player gets 0.5 - 3.0% of the bet amount in RLT to Ethereum account used to place a bet (p. «RLT token distribution»). Tokens are paid regardless of the game result.
After getting tokens the player can use them for different purposes:
The amount of bonuses:
Test period 03/14/2017 - 03/21/2017 | 3% |
Test period 03/22/2017 - 03/29/2017 | 2.5% |
Test period 03/30/2017 - 04/06/2017 | 2% |
Test period 04/07/2017 - 04/14/2017 | 1.5% |
after 04/15/2017 | 0.5% |

The affiliate program will gradually replace «bounty» rewarding system with more economically effective promotion one.
Every participant of the project can take part in the affiliate program by getting a personal link to be advertised or spread:
What is strongly restricted:
Players following the affiliate link start being permanently assigned to the user who attracted them after placing the first bet. The affiliate reward is equal to 0.1 - 0.5% of each bet (not depending on the game result). The exact amount will be defined at the moment of the affiliate program launch and can be modified for achieving better effectiveness.
The affiliate is paid RLT tokens reward instantly by the smart contract as soon as the player referred places a bet.
Here we provide several examples to understand system work algorithm*:
You post your affiliate link on your Facebook page and 7 users follow it. Only one of them installs MetaMask extension and places the first bet in amount of 0.1 ETH. At the moment the user starts being assigned to you and you get your first reward calculated according to the formula: Bounty = Bet * coef / RLT rate (p. «RLT tokens issue») 0.1 * 0.005 / 0.0015 = 0.333 RLT.
During the following months the user places bets with total amount of 18 ETH in 100 games providing you with the reward 18 * 0.005 / 0.0015 = 60 RLT.

ICO date has been announced by SmartPlay.tech gaming platform. Crowdsale will start on the 7th of April, 2017 at 12:00 GMT and will last for 3 days.
Initial RLT token price will comprise 0.0015 ETH with the price rising every hour in the process of ICO.
During crowdsale it is planned to sell RLT tokens in the amount of $100 000-150 000 in ETH currency according to the rate at the moment of sale that is approximately equivalent to 2 500 000 tokens. ICO will be considered valid if the sum of funds raised reaches at least $100 000 according to ETH rate at the moment of crowdsale .
The details on upcoming ICO can be obtained here.
We don’t support the idea of collecting millions of dollars for obscure purposes. We consider negative experience of other ICOs where investors didn’t get what they wanted. That’s why we are set real goals and are planning to collect the funds only for definite purposes aimed at achieving the result.
Efficient work and supplementary costs (excepting for salary costs) currently require $2 500 - $3 000 per month. Besides, effective advertising of the game demands constant budgeting.
The goals we are planning to achieve using the funds collected in terms of ICO:
As soon as our project SmartRoulette.io achieves the goals planned we will start developing the following games:
It is possible that each of the games will be followed by its own ICO (Crowdsale) and the issue of a new token.
The mechanism of tokens purchase is quite simple. At the moment of ICO start we will publish the address of the smart contract that sells tokens. In case of depositing no less than 0.15 ETH and no more than 500 ETH, the contract will instantly send the corresponding amount of tokens to Ethereum address used to send the payment. The total amount of purchases using one and the same address is limited and comprises 500 ETH. The acceptance of the funds will finish in 3 days after ICO start and all the tokens are sold.
On April 10, 2017 three-day crowdsale of SmartPlay.tech platform has ended. Total sum raised comprises 2873.592 ETH or $126 150 at the exchange rate as of 04/10/2017. The number of tokens sold is 1 874 170. The founders consider ICO to be successfull, as just for the first day of sales they managed to raise the planned amount of $ 100 000.
