Achieving a high score in Sonic Advance involves more than just finishing the stage. Several factors contribute to your final score:

- Time Bonus: The faster you complete an act, the higher your time bonus. Speedrunning is crucial for top scores.
- Ring Bonus: The more rings you have at the end of an act, the higher your ring bonus. Try to finish with 50+ rings for a significant boost.
- Enemy Bonus: Defeating enemies contributes to your score. Chain multiple enemy destructions for combo bonuses.
- No Damage Bonus: If you complete an act without taking any damage (i.e., without losing any rings), you receive a substantial bonus. This is often the hardest bonus to achieve.
- Perfect Bonus: Some games in the series offer a 'Perfect' bonus for collecting all rings and taking no damage. While not explicitly stated in Sonic Advance, aiming for this will naturally lead to high scores.
To maximize your score, focus on a balance of speed, ring collection, and careful enemy management. For the ultimate score, aim for a no-damage run with a fast time and as many rings as possible. Practice specific acts to learn enemy placements and optimal routes.
