Once a day, LWOS offers a lottery. Players can buy tickets. Only one winner is possible. The winner will win the amount of satoshis of the lottery (2% fee on the gains.). Each participant will earn 10 games and the winner 10 games per slice full of 10. The winning ticket is designated with the value of the nonce of the last Bitcoin block at the time of the draw. The lottery closes 1 minute before the draw. More information on Forum
