My economist friend M., having pointed out that if we want more players in our instant games, we might want to be more generous with prizes (what he calls “pricing for penetration”), followed up with an insight about how quickly we need to prove our generosity. It is pointless, he says, to focus on prizes that are unlikely to be won unless a player is spending big. The challenge is to design games that will keep players engaged who are spending small. I related our conversation in NASPL Insights October 2013.
