With that, we've gotten a good foundation on how to add ads to our game. Hopefully, you can see how easy it is to implement and can think of new ways to engage players to have the best experience possible. Over the course of this chapter, we discovered how to set up Unity Ads. We then saw how we could create simple ads and then learned how to react to the player's actions with ad callback options. Afterward, we saw how we could add in rewards for players using opt-in advertisements to the game and added a cooldown to the system to make the game less annoying for players.
While this is a valid way to monetize our games, we will dive into the other most popular form of in-game monetization in the next chapter: in app purchases.
