The Challenge Board is a grid of specific in-game achievements that, when completed, unlock various rewards such as characters, stages, custom moves, equipment, and trophies. There are three boards, each with increasing difficulty. Completing all challenges is a true test of your mastery of the game.

How to Complete Challenges
Each square on the Challenge Board represents a specific task. These tasks can range from simple (e.g., 'Play 10 Smash battles') to highly difficult (e.g., 'Clear Classic Mode on Intensity 9.0 with every character without losing a single stock').
- Read Carefully: Always read the challenge description thoroughly to understand its requirements.
- Track Progress: The game often tracks your progress towards challenges, so you don't have to remember every detail.
- Use Hammers: If you're stuck on a particularly difficult challenge, you can use a 'Hammer' to instantly complete it. Hammers are rare rewards themselves, often earned by completing an entire row or column of challenges. Use them strategically on the most frustrating tasks.
- Experiment: Many challenges require specific character actions or mode completions. Don't be afraid to experiment with different characters and strategies.
The Challenge Board is your primary source for unlocking many of the game's hidden secrets and content. Regularly check your progress and prioritize challenges that unlock desirable rewards.
