Average Mobile In-Game Purchase: $14

Some interesting data on in-app purchases.

You probably know that only a few percent of players of free games actually go ahead and pay for something within the game. But here's the part you may not know: According to Flurry, the average in-game purchaser racks up $14 in charges on a game. It seems that if you like a game enough to spend some money on it, you really like it.

Their take-away lesson for game developers: You're whale hunting. Whales, that is, in the casino phrasing, which are players who spend big money.

Find a way to attract whales, and you're going to make some money.
