If you belong to a football pool/hockey pool opr anything else where you bet on your favorite taem or player, the person that runs the pool/sports betting, wants to get your interest in signing up and playing by offering you a list of bonuses. They can be:
sign up bonuses ( just to entice your interest in signing up right off the bat)
referral bonuses - cash rewards for referring others to join the betting game.
place bonuses - let\'s say one of every 13 bets gets an extra of $35 dollars. They also call it a bonus of the day.
You can get a bonus for a particular player who kicks most field goals in a certain month (American football). If you pick a player whose odds are high on field goals and you picked him anyway, you will get extra bonus points.
Now, to place the bonus means, I think to place the win money next to whatever you bet on. Just my guess because the rest of the sentence could help me more.
