So this week we can play for a $100 Starbucks Gift card for 500 Points, 1 winner per day. Since it was explained the the game software picks a random time of day to make an award available and the first person to play after that time wins.
So with only 1 per day, if say the game software randomly chooses to make that reward available at 8 AM, then everyone else who plays the rest of the day is playing for a non-existent prize.
I would have to believe if cash were involved, this might be questionably legal, but since it is only points without a cash value, it is all in fun?
