For those who played NatGeo Challenge Wild Life, the gameplay here is very similar. However, the game is much, much simpler to Platinum. The only real roadblock is that the game requires 3 controllers to Platinum. There are a large number of puzzles (jigsaw, square, sliders) to complete but the difficulty is quite low. Also, this game includes a new mode, Explorer. Explorer is basically like Risk but battles are fought with trivia.
Step 1: Explorer
You will only need one controller here, even for the multiplayer trophies (Hot-Seat mode allows all players to take turns on the same controller). You will probably need to play 3-4 games of Explorer to get all trophies. In each game, choose two players and make it your goal for each of the two players to completely conquer at least one continent. The game will end if either player gains 2200 points so plan accordingly. In one match, Player 1 will need to conquer at least 18 territories. In one match, you will need to use 4 players (again, 1 controller) and allow Player 1 to win. Last, in one match Player 1 should focus on winning all competitive puzzles. Read specific trophy guides for details - trophies included in this step are: One Small Step; Dr Livingstone I Presume?; Have a Captain Cook; The Grand Tour; Silks and Spices; Voyage of Discovery; The Inca Trail; Hearts and Minds; On a Roll; All For One...; Diversity
Step 2: Puzzles
First, play one game of 2-player Puzzle Attack and allow Player 1 to win. Then complete all the puzzles in individual puzzle mode. Completing puzzles unlocks new puzzles. All in all you will need to complete 90 puzzles, each requiring about 2-3 minutes. You will attain Prince of Puzzles; Jiggery-Pokery; Lord of the Dance; Squared Away; Square Eyed; Slipping and Sliding; Let It Slide from this step.
Step 3: Quizzes
You will need to win at least one Long Quiz using three controllers. Also, you need to attain minimum scores (not difficult) in Short, Medium, and Hard Quiz lengths. You also need to complete five short and five long quizzes (1 player). Lastly, you will need to end at least one quiz with a negative score (lose points on the betting rounds). This step should take no more than 2 hours. You will attain Enter A New Challenger; Counter-Intelligence; ...One For All; Child's Play; Mommas and Poppas; Bragging Rights; Quiz Hero; Quiz Lord; Quiz Titan; Columbus Salutes You! from this step.
BAM! You're done.
