Hmm we should do a study, start spins at different times of day, around 9-10am server time, 4-5pm and 0:00-1:00am, and record (very quickly) the number of spaces with a)game coin prizes b)'great' prizes (value over 250), c) moderate prizes (value around 50), and junk prizes (single trash items, x amount of food, junior battalions, etc.), as well as the reward category you actually receive, as well as the time you rolled at.
