The points you win on the slot machines will count in the daily competition, were all the players from that day is ranked, as you can see by clicking in the top left corner of the slot machine. Every day, today's position is reset, and you earn points after how you place on the day. Today's first place gets 100 points, second place gets 90 points, etc. The points you get from your position in the todays table will then be transferred to the overall point table for the weekly competitions -which will determine the final winners of the week.
When the competition ends, you win prizes after your placement in the overall point table. Every week, the competition begins again and you can see your posistion from last week when you look at this week's total score.
