Most games include at least two rewards.
The "prize" amount is determined by how many cards are bought by
players and is awarded to whoever wins. If more than one person wins a game,
the prize split evenly.
The "jackpot" builds over time and is won if a player wins a game in
the alotted number of calls. Just under the jackpot amount there's a section
that says "win's on calls" and two numbers, for example 1-30. If your
card wins on calls 1 through 30 you win the jackpot.
"Cover All" games run hourly and have large prizes, often well over
$1000. Like the jackpot, there will be a "win's on calls" range. If
no one wins within that range, the prize is lowered and the game continues
until someone wins.
