//Spielleys Divide Drain and Destroy minigame v 1.01

//99% of eth payed is returned directly to players according to their stack of shares vs totalSupply
// players need to fetch divs themselves or perform transactions to get the divs
// 1% will be set aside to buy P3D with Masternode reward for UI builders
// 100% of vanity change sales will go to buying P3D with (UIdev MN reward)

// Game Concept: (inspired by a hill type idea for kotch https://kotch.dvx.me/#/)
// - Divide: Convert eth spent to buy shares factor eth value *3 
// - Drain : Drain someones shares, enemy loses shares eth value *2, you gain these
// - Destroy : Burn an enemies stack of shares at rate of eth value *5

// Steps of the transactions
// 1: update total divs with payed amount
// 2: fetchdivs from accounts in the transactions
// 3: update shares

// no matter your innitial shares amount, 
// you'll still get eth for getting destroyed according to your shares owned
