The odds of winning a prize depend on two factors:
How many depositors there are and
How many tickets you have accrued
How the drawing works:
At the end of the week, we mix all the tickets together and randomly pick the winners - starting with the largest prize amount (by value) and then go down the list of prizes by prize size value (largest first).
Once the first winner is picked we then remove the rest of that winner's tickets from the drawing since a user can only win one prize per drawing.
After the winner's tickets have been removed, we then proceed to pick the next largest prize based on denomination.
We then continue steps 1-3 until all the prizes have been awarded.
