Mechanism

The whole game mechanism is dominated by smart contract under immutable operation automatically. Once the smart contract is launched, it cannot be amended, such as Bitcoin. by When a member transfers USDT (ERC-20) into smart contract to join the game, the system would instruct the smart contract to assign same number of “Citishare” (CTS) tokens for playing the game. The tokens are used to settle in smart contract for convenience and simplicity, and reducing the cost. The exchange rate of CTS to USDT is 1:1.

There are 2 smart contracts for the game. One is with lower threshold ranged from 60 to 300 USDT, another one is ranged from 300 to 3,000 USDT to segment different categories for various demands.

When the game is opened, the system would automatically check the balance of each user whether his/her account has enough USDT to play the game. It means the amount balance has to meet the maximum price of each session. If enough USDT, the system will deduct the maximum price of that session (e.g. Ferrous metal ore is ranged from 60 -120 USDT, the smart contract will deduct 120 USDT) and then join the game; if not, do not join the game. The reason behind the pre-deduction of the maximum price of the session is to ensure the settlement is completed simultaneously by blockchain without the shortage of USDT of either member account. Therefore, if a member discovers a ferrous metal ore below 120 USDT, the remaining would be refunded for the member into the smart contract.

They system would also check how many tickets of each user has when the game is opened. The ticket is like the admission ticket available to join the game. One ticket equals same probability with others who hold one ticket too. If a member holds two tickets, it means the member qualifies two times of probability with those who hold one ticket only. After settlement, if the member gains a metal or meteorite, the member will be reset and assigned 1 ticket for next round of the same session of game. If the member loses to discover a metal or meteorite, the member will be assigned 1 more ticket, in total of 2 for next round of same session of game. There are 8 different sessions per day with different amount of USDT to join.

Example of the tickets assigned:

The number of tickets assigned is independent of other sessions. Each session of each member is counted as independent number of tickets. It meets higher fairness standard that each member gains fair probability to each session instead of lower probability after discovering a metal or meteorite in other sessions.

The system is set a bingo rate of 30%, meaning that if there are 100 members joining the same session of game, 30% of them, that is 30 members can discover the metal ore or meteorites. The system would round down the number of discovery to an integer if the remainder exists. Warmly remind that it is impossible to allow 50% bingo rate or above in order to protect the healthy development and longevity of the game. On the other hand, if the bingo rate is set too small, it would eliminate the intention and interest of members. Therefore, a balanced bingo rate is valid for the game.

The charges

Members have to pay following costs after they can discover any metal ore or meteorite, no front-end cost would be charged:

1.)   Smart contract operation cost – 1% paid by old owner

l   Every function of smart contract is required the cost to run, including assigning tokens, open game, checking balance of each member, array of members’ tickets, settlement of game, distribution of incentives, etc. All individual functions combine together to be a fully decentralized and complicated system automatically to run in blockchain of ERC-20.

2.)   Referrer’s incentives – 1% paid by new owner (0.5% for referrer and 0.5% for referrer’s referrer)

l   To arouse more members to play the game together, an effective incentives scheme is necessary. A passive and relatively long term income can be generated after referring more friends and members to join together.

3.)   Operation cost – 1% paid by new owner

l   Customer services and other operation costings are essential to smoothen each part of the game

Upgrading and splitting

After a member discovers a metal ore or meteorite, the price would be increased steadily within certain interval. When the price of the metal ore or meteorite increases to meet the price of next price range (next session), the metal ore or meteorite will be upgraded to next level. When the price of metal ore or meteorite meets the maximum level of each smart contract, the metal ore or meteorite will be split into different categories to ensure the healthy development of the game as follows:

Smart Contract 1: When the price meets or above 300 USDT, then it will be split into 1 Non-Ferrous metal (120 USDT) ore and 3 Ferrous metal ore (2 X 60 USDT + remaining one)

Smart Contract 2: When the price meets or above 3,000 USDT, then it will be split into 1 Gold meteorite (1,200 USDT), 1 Lithosiderite (800 USDT), 2 Aerolith (2 X 300 USDT ) and 1 Aerosiderite (remaining one of 400+ USDT)

Withdrawal

Members can apply for the withdrawal anytime through the system. Once a withdrawal instruction is placed to the smart contract, the smart contract will be redeemed USDT based on the number of CTS tokens (exchange rate is 1 CTS: 1 USDT) and then transfer the number of USDT into the member’s registered wallet. The registered wallet address is acted as the unique identity to represent the account owner. No other wallet addresses are accepted except the registered wallet address at the beginning for the account. Please memorize and secure the registered account information in order to protect your assets. There are no platform wallets provided by Citistone for members to fully utilize the autonomy of smart contract operation without any bias, unfairness and centralized authority.
