ICO stage is live - up to 50% Bonus!

EtherJack is a jackpot game, based in the Ethereum blockchain.

The game rules are simple: there’s a massive jackpot, and people are placing bids to claim it, within allowed time after the last bid. If no bid comes, the last to claim gets it. If bids keep coming, the jackpot grows further.

Currently when the ICO stage is running, the jackpot is being collected in exchange for JACK tokens, which the investors will then use to get a cut of all bids made in the game, use it for bidding when bid price grows high, or just resell it at a higher price (the game can do that automatically).

JACK is a custom ERC20 token with address 0xe64d5f33E28387855d33980719f27f0d579392aF

With the bounty program we are awarding JACK. The value of JACK is 0.004 ETH to 0.006 ETH during ICO. When the game starts, it will cost 0.01 ETH, and due to the way the game rules are, the price will grow automatically during the game. After 1000 bids (which is no later than 35 days from game start) JACK will cost 0.07 ETH, and after 5000 bids (67 days from start max) 0.31 ETH, and so on.

Bounty rewards will be added to your Vault deposit with Croupier. This makes you start receiving bid and token sale dividends immediately. You can then withdraw them to your wallet or put on sale if you choose so. Bounty Program Announcement

The Program will run until the end of the ICO process + 2 more weeks during the game phase.

A total of 2.5% out of 1M JACK Tokens created, are reserved for the Bounty Campaigns. That means that 25 000 JACK tokens will be available. 

The JACK token ETH price solely depends on the game progress, its price change rules are hardcoded, and its value follows the jackpot growth. Starting from 0.006 ETH at the ICO and 0.01ETH at the start of the game, the JACK token price will increase after each 100th bid made, by 0.006ETH. After 1K bids (which can’t take more than a month due to the bid time limits) the JACK token will cost 0.07 ETH (over 10x compared to the ICO price). After 10K bets (max 3 months from game start) it’ll cost 0.61 ETH (almost 92x the initial price).
