ETHERJACK.IO

 

EtherJack.io is the first fully smart contract based jackpot game. The core game process is safe and secure, running completely on-chain, operated by contracts with disclosed source code, with only optional extensions basing off-chain.
In EtherJack, the whole game process is controlled by participants, in this sense it’s a massively multiplayer community game. The rules are simple: bids fill up the jackpot, the last to bid wins and gets the huge prize. The developers (or anyone else) can’t affect the game process, can’t manipulate or adjust it, or change the rules on the fly. The fixed contract code ensures the game is transparent and fair to all participants.

EtheJack.io have fully transparent Live Game Simulation in their ICO Stage.The Game have basic rules are quite simple. There’s a jackpot, at every moment it’s claimed by a player (the last to bid), and there’s a countdown timer running. If someone bids (by sending an amount of Ether to the Jackpot smart contract), that person now claims the jackpot, the bid is added to the jackpot, and the timer is reset. If nobody claims the jackpot by the moment the timer runs out, it goes to the last person who placed a bid. Over time, the bid price goes up (from 0.005 ETH, up to over 1 ETH), and timer duration goes down (from 3 hours down to 5 minutes). There’s a second level meta-game present: each 20th, 50th, and 100th bid also win “minor prizes”: 10% of bids’ worth during the corresponding period.
For example, each 20th bid wins 10% of Ether used for last 20 bids. If all of these bids were made in Ether, and the bid price didn’t change, it will be precisely double the bid price. If some of the bids were made in JACK, the amount will be smaller. If the bid price changed, the amount will depend on when within that interval the price changed. Everything described above is entirely implemented in smart contracts with published source code, which means it can be verified and audited by the public. All smart contracts’ variables are made public for the same purpose. If a player bids double, triple, etc. amount of bid price, they buy JACK tokens for the extra amount. Tokens can be used to place bids without spending Ether later, for investment, or to be sold later at higher price. See “JACK Token Economy”.
When the game is running, the bid price changes over time. The bid price depends on the total amount of bids made, and is defined by the following formula:


Since during the game JACK is purchased or sold at this price, and 1 JACK can replace this amount of Ether in a bid, this price naturally corresponds to the JACK intrinsic value during the game stage.

JACK Token Economy”ICO,to accumulate a solid Jackpot and kick-start the game.The plan is to collect 333 ETH and start the game with it.Jack Token AMOUNT is Limited and the Tokens Stored in the Vault provides dividends of their Owners.Token for Betting are BURNED.The main components of the game—JACK tokens, bets, and the jackpot—are written as Ethereum smart contracts, for which the source code is published. This means the game is fully transparent and fair, and anyone can audit it.

Token smart contract:

Smart Contract
The main components of JACK tokens-tokens, offers, and Game Gifts-are written as smart contracts by Ethereum, whose source code is published.

This means the game is completely transparent and fair, and anyone can audit it.

• Defining the JACK Token and its transfer function
• Handle deposit and withdraw (tap transfer to Croupier and
  apply custom logic)
• Handle token bids (intercept transfer to Jackpot and apply custom logic)
• Handling of freezing and freezing of deposit (API only available for Croupier)
  token sales through Jackpot contract

There is a fixed supply of 1 million JACK, which can only go down. Every time there is a sign
Used to bet, it is burned irreversibly, thereby reducing the total supply. JACK Tokens can be transferred freely between players or traded on the exchange. When Tokens are sent to Croupier, they will be counted against the user's deposit with an on-chain Croupier. Later, all deposits can be withdrawn, on-chain wear The deposit data is stored in blockchain. If the deposit owner wants to sell the token through their Jackpot contract Ask Croupier to do it. The Token Contract froze the deposit by Croupier's demand, thus making it available for off-chain manipulation on the Croupier side.
If the user wants to stop selling and return JACK back to the deposit, Croupier will request an unfreezing deposit, which will refund the deposit amount back to blockchain Jackpot Smart Contract

Jackpot smart contract runs the game:

• ICO Stage: sells tokens for investment
• Start the game when ICO destination is completed
• Ether Bid
• Token Bid
• Tracking and payment of small rewards
• Game ending conditions
• Jackpot Payment

Economy Token JACK
Overview of JACK

JACK Tokens is the game's internal currency. JACK has no fractional denominations, the symbol is "JACK". The JACK tokens are obtained during the ICO phase, and can be obtained later in the
games, and can be used by investors (ICO participants) and players (non-ICO games articipants) to take advantage of game operations, utilizing JACK's the price grows, and use JACK to place the offer without removing the Eher.

Token JACK is the token ERC20, can be seen at the following address:

Symbol: "JACK", decimal: 0.

• The token Solidity code is available for public review at eterscan.io.
• The Theory Behind the Value of JACK
• The JACK token has an intrinsic value because of its two token functions:
• It can be used for non-Ether bidding (hence the value is not less then the offer price at any time);
• The holder can get some of the value of all the bids made and the new JACK tokens sold through Jackpot (dividend) contract.
• The value of JACK is supported by the presence of jackpot prizes, since the jackpot is the driving factor behind players who place bids.
