In the "Luck & trade" tab you spin the wheel of fortune daily – more often with a rank. Prizes go straight to you, the history shows the latest wins of all players.
The wheel colours show the rarity: grey = common, green = standard, blue = uncommon, purple = rare, red = epic, gold = jackpot (also wins the wheel jackpot). The legend below the wheel lists the chance per colour.
Lottery: a ticket costs 50 scrap, at most 20 tickets per player. The draw is daily at 20:00 – the more tickets, the better your chance. The winner gets the whole jackpot in the mailbox. Without tickets the jackpot rolls over to the next draw.
The tab also shows your wheel stats, the wheel jackpot and your current lottery odds; you get a reminder before the draw.
