There are several different ways that you can play
Nat Geo Challenge! Wild Life, both alone and with up to 4 friends. First up is Quiz Mode. Here, you can choose to play with up to four players. You select from one of the four series: Amazing Planet, Dangerous Encounters, Aquatic Life, Predators Vs. Prey, or Mega Quiz, which has questions from all four series. Once you choose a series, then you choose the quiz length from 40, 60, or 80 questions. After that, you select who is on what team. You can even have everyone on the same team if you don't want to compete. If there is more than one person on a team, whoever presses an answer first is the one that answers the question. The game will respond to all controllers, so you're not stuck just sharing the same controller. After that, you choose your difficulty and you're ready to play. All the series are unlocked in Quiz Mode from the beginning and you will be told what the correct answer is if you miss a question. There is a time limit, so you want to make sure to answer quickly! You will not unlock anything new in Quiz Mode however.
Next up is Quest Mode. When you start a new game, there is only one series unlocked, Amazing Planet. You'll choose your difficulty and then start playing. There are a few episodes unlocked inside. Each episode is 10 questions about a specific topic. When you select an episode, you'll get a brief introduction video to the topic and then there are photos and some fascinating information about the subject as well. Make sure to read it all, because you'll need to know some of it for sure. When you're ready to begin the questions, select Play. You'll get a question and four possible answers. If you miss the question, it does not tell you what the correct answer is. There's no time limit though, so if you want to get perfect on the first try, you can always open the internet and Google for the answer. If you replay an episode, the questions will be the same and in the same order. The possible answers are the same as well, but they're not in the same position so make sure to read things carefully. Most questions are purely trivia, but some are pictures that you need to identify or letters that you have to unscramble or other fun things. Once you answer all 10 questions, you'll be given the option to retry or continue. Once you choose to continue, you'll find out what you unlocked. The better you do, the more things that you unlock including episodes and puzzle pieces. If you want all of the puzzle pieces and stat attack cards, you'll need to get 10/10 on every episode!
When you want to take a break from trivia, you can choose Stat Attack. You'll have unlocked more Stat Attack cards in the Quest Mode to play with, so you might as well use them. Stat Attack is a very interesting card game that requires you to choose cards based on what stats you think your opponent is going to choose. I can really see some fun potential with it if you have someone to play with a lot! When one player can no longer beat the other because they've collected so many cards, Stat Attack is over. There are also puzzles available that you can play by yourself when you're alone, or even with someone else. There are jigsaws, square puzzles, and sliders. Personally, I like the jigsaws best, but they're all quite fun!
