So the first and the last

EtherJack.io is the first fully intelligent contract based jackpot game. The basic game process is safe and secure, running completely chain-managed by contracts with disclosed source code, with only optional extensions basing off-chain in EtherJack, the entire game process is controlled by participants, in This way, it is a massively multiplayer community game. The rules are simple: The bids fill the jackpot, the last a Un'Offerta fare wins and gets the footprints award. Developers (or anyone else) can not influence the game process, can not manipulate or adjust, or change the rules on the fly. The fixed contract code ensures that the game is transparent and fair to all participants.

EtherJack is a jackpot game, based in the Ethereum Blockchain.
The rules are simple: there is a huge jackpot, and people are putting bids to claim it, within the time allowed after the last offer. If not offered, the last to claim gets. If the bids keep coming, the jackpot grows further. The game is 100% transparent and fair (thanks to Smart Ethereum contracts), and it all depends only on the participants, not on developers. We are announcing the beginning of the ICO stage of the game. This is the stage where the jackpot is well formed, and Jack tokens (to learn more about them below) are distributed at much lower prices than the game stage. The collected jackpots will attract the players by placing the bids, and the Jack you get will help you get a cut of the bids. The game will also automatically sell your Jack to new players at a growing price if you want.

What is the game?
After this phase is complete, the ICO will have at least 333 ETH jackpot in it, and the game will start. Players will make an offer (starting at 0.01 ETH). Each offer claim the jackpot and start Countdown timer. If no one else has put bids before the timer runs out, the player to make the latest bid get the whole jackpot. This will not happen so easily, however, because others will want to put another bid and claim the jackpot for themselves, instead, at the last moment. Someone will make an attempt to not let the second person to win, and so on. Other offers placed, short is the timer (3 minutes to 5 minutes), and the higher the offer price (0.01 to 0.1 0.5 eth eth and TOP without limits). Check out EtherJack.io to see the simulation of the game running, and read the version of the illustration of the rules of the game. Games implemented as Smart contracts with published source code. Jack's source code Token published too. Good developers or airport bots (off the network component of the game) can affect the course of the game in any way other than what is available to others, can be verified in code contracts. More details on the role of the developer and the airport can be found white paper. EtherJack.io is a combination of good luck game, patience, time and investment. Each participant has a very real chance of winning most of the ether. Proved mathematically.

What is being sold?
During the ICO stage of the game, the jackpot contract is selling Jack coins (a custom ERC20 token used in the game mechanics) at a discounted price as long as there are at least 333 ETH in the jackpot. The price of Jack tokens during ICO starts at 0.004 ETH for Jack, and will reach 0.006 eth by the end of ICO. At the beginning of the game, the price will jump to 0.01 ETH to grab and continue to grow as the bids are increasingly made in the game. The price of Jack is defined by game rules (the Smart contract), and the way the game is designed ensures that Jack is worth at least the nominal price at all times. You can read more about this and why it is so, in the white paper.

Token Jack

Jack's chips are the internal currency of the game. Jack has no fractional denominations, his symbol is "Jack". The token Jack is a ERC20 token. The token Jack holders benefit in a number of ways:

Offer with a token instead of ever increasing amount ETH
Memorize the chips in the vault and get a cut from every offer the ETH made
Sell tokens to players at the ever increasing price via the vault
Sell to anyone through trade or personally.

Symbolic Sale

It is in both ICO ' investors and the developer's interest to have as many possible bids placed, and the largest possible amount of Jack chips sold during the game stage. So it is up to the creators to attract as many people as possible in the game. Funds raised through the ICO as well as the home share of the running dividends will be used for acquiring new players. When you buy traps, buy in larger amounts and get volume discounts up to 25%. The discount is provided only within a single transaction, so try to buy in larger pieces for maximum profit.
