To achieve 100% completion in Super Mario Bros. Wonder, you need to meticulously complete a variety of tasks across all levels and worlds in the game. Below is a clear and structured guide to help you navigate through the requirements:

Tasks for 100% Completion

1. Complete Every Level:
– Make sure you finish all stages in the game. After completing the main storyline, you can access the map screen to review any levels you might have missed.

2. Reach the Top of Every Goal Pole:
– Upon finishing each level, aim to hit the very top of the Goal Pole. This step is crucial as it signifies that the level is fully completed.

3. Collect All Purple 10-Coins (10-Flower Coins):
– Search for and collect every purple 10-coin scattered throughout the various levels. These coins function similarly to Star Coins from previous Mario titles. Gathering all of them will reward you with one of the completion medals.

4. Find All Secret Exits:
– Some levels contain hidden secret exits. Locating these exits is essential for full exploration; a green checkmark will appear next to levels where you have discovered all secret exits.

5. Collect All Wonder Seeds:
– Similar to the purple 10-coins, Wonder Seeds are collectibles that you must gather from each course. Collecting all Wonder Seeds will earn you another medal.

6. Collect All Badges:
– There are a total of 24 badges in the game. You’ll acquire these badges by completing specific tasks or achievements throughout your adventure, contributing to your overall completion percentage.

7. Purchase All 144 Standees:
– Make sure to visit the Poplin Shops in the game to purchase all available standees. Completing this requirement will also earn you a medal.

Tips for Achieving 100% Completion

– Utilize the Map Screen:
– After the main story is complete, leverage the map screen to identify any incomplete levels. Look for black rectangles that indicate levels needing additional exploration.

– Follow Walkthrough Guides:
– Comprehensive guides from trusted resources such as IGN or Game8 can be invaluable. They often provide insights into discovering hard-to-find collectibles and secret exits.

– Check for Green Checkmarks:
– On the map screen, levels that show a green checkmark indicate that you have fully completed all requirements, including collecting all items and finding all secret exits.

By diligently following these guidelines and ensuring each task is accomplished in every world, you will successfully complete Super Mario Bros. Wonder to 100%. Good luck, and enjoy your adventure!
