Each section has multiple games because there are multiple ways to approach any problem or goal. You may find that some of the games work better for you than others, or maybe some are just more intuitive for you than others.

Give every game a fair shot, but in the end, don't worry too much about whether you've mastered every game.

Instead, ask yourself "Have I accomplished the goal of this section?"

For example, if you've reached the end of the "Position" section of the course, don't worry about whether your pup is perfect at playing "Profit Position Black Hole." Instead ask, "Does my pup generally understand where the profit position is? Does my pup seem to find value in the profit position?"

If so, that's great progress and that's all that matters!
