JACK ICO & GAME: The First Or The Last!

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 Allocation:

The JACK token holders benefit in a number of ways:
• bid with a token instead of ever growing ETH amount;
• store the tokens in the Vault and get a cut from each ETH bid made;
• sell tokens to players at ever growing price via the Vault;
• sell to anyone via exchanges or personally.
