Your Guide to Upgrading in Sonic Speed Simulator

1. “Gotta Go Faster!”

Welcome to Sonic Speed Simulator, the fastest game on Roblox! If you’ve just jumped in, you’ve probably realized that speed isn’t just given—it’s earned. To unlock exciting new worlds like Chemical Plant and Metal City, and to keep up with veteran players, you need to upgrade your character. But how do you go from a slow-stepper to a blue blur?

This guide will break down every essential method for upgrading your character as of June 2025. We’ll cover the core mechanics of Leveling Up, the crucial Rebirth system, and the game-changing power of Pets and Trails.

2. The Foundation of Speed: Leveling Up Your Character

Leveling up is the most fundamental way to increase your character’s power. It’s the first upgrade system you’ll interact with and remains important throughout your entire journey.

• How Leveling Up Works: As you play, you gain Experience Points (XP). Every time your XP bar fills up, your character’s Level increases by one. You can see your current level and XP progress at the bottom of your screen.
• The Best Ways to Earn XP Fast:
  • Collecting Rings: Every ring you pick up grants a small amount of XP. Running through dense ring paths is a steady way to level up.
  • Hitting Dash Pads and Ramps: Every jump ramp, booster, and rail you grind gives you a nice chunk of XP. Actively using them is much faster than just running.
  • Completing Quests: Pay attention to the quests on the left side of your screen. These often provide massive XP rewards and are one of the fastest ways to level up, especially for new players.
• What Each Level-Up Increases: Each time you level up, you permanently increase your character’s two core stats:
  • Speed: This dictates your maximum running speed.
  • Power: This determines your jump height.

3. Reaching Max Level and Beyond: The Rebirth System

So you’ve hit the maximum level (e.g., Level 250)—now what? The key to true speed lies in the Rebirth system.

• What is a Rebirth and When Can You Do It? A Rebirth is a way to reset your character’s level back to 1 in exchange for powerful, permanent stat multipliers. You can perform a Rebirth once you reach the maximum level and have enough Rings to pay the fee. The Rebirth altar is typically located in a central area of Green Hill Zone.
• The Pros and Cons:
  • Pros: You gain a permanent multiplier to all future XP and Ring collection. This means you’ll level up much faster on your next run and earn Rings more quickly. You also unlock exclusive new Trails.
  • Cons: Your Level, Speed, and Power are reset to Level 1. You will feel slow again, but only temporarily. The cost in Rings for each subsequent Rebirth increases significantly.
• Is It Worth It? Absolutely. Rebirthing is essential for long-term progress. A player with 10 Rebirths will level up and earn Rings exponentially faster than a player with zero Rebirths, even if they are both at the same level.

4. Your Companions in Speed: How Pets Boost Your Stats

Pets are arguably the most important upgrade component in the game. A good team of pets can dramatically accelerate your progress.

• Understanding Pet Tiers: Pets come in different rarities, from Common to Legendary, and then into exclusive tiers like Mythical and Event pets. The higher the rarity, the better its base stats.
• How Pet Stats Work: Each pet has multipliers that directly boost your earnings. For example, a pet with a 2.5x Ring multiplier means you get more than double the Rings for every one you collect. The same applies to XP and Event Currency. Equipping a team of pets with high multipliers is the key to fast farming.
• How to Get Better Pets: Pets are primarily hatched from eggs found in Vending Machines scattered across the worlds. Use your Rings and Chaos Orbs to buy eggs from higher-level worlds, as they have a better chance of containing rare and powerful pets. Limited-time events are also the best source for incredibly powerful, exclusive pets.
• Evolving and Fusing Pets: You can combine multiple copies of the same pet to evolve it into a “Radiant” and then a “Shining” version, which significantly boosts its multipliers. This is a crucial step for building an end-game pet team.

5. Leaving a Mark: The Power of Trails

Trails are the visual effect that follows your character as you run. They aren’t just for looks—they provide a small but important boost to your stats.

• What Are Trails and How Do They Help? Each Trail provides a passive multiplier to your Speed, Rings, or XP. While the boost is smaller than what pets provide, it’s a permanent buff that’s always active.
• How to Equip and Upgrade Your Trails: You can equip Trails from the “Customize” menu. You get better and more powerful Trails primarily by completing Rebirths and participating in special events.

6. Farming Strategies: Getting Resources Faster

To upgrade efficiently, you need to farm resources effectively. Here’s a quick guide to the best methods.

7. Pro Tips for Efficient Upgrading

Follow this checklist to make sure you’re getting the most out of your playtime.

Daily Upgrade Checklist

• [✔] Complete Your Quests: Prioritize your daily and weekly quests for massive XP and Chaos Orb rewards.
• [✔] Participate in Events: Limited-time events offer the most powerful pets and trails in the game. Don’t miss out on them.
• [✔] Claim Free Gifts: Don’t forget to claim your free spins and time-based gifts from the shop menu.
• [✔] Upgrade Your Pet Team: Always be working towards evolving your best pets to their “Shining” forms.
• [✔] Rebirth When Ready: As soon as you hit max level and have the Rings, perform a Rebirth. Don’t wait.

8. Conclusion: Your Roadmap to Becoming the Fastest Thing Alive

Upgrading in Sonic Speed Simulator is a satisfying and addictive loop. Your focus should always be on increasing your multipliers to make each subsequent step faster and easier.

• The Takeaway: The core upgrade path is simple: Level up by completing quests and using dash pads. Once you hit the max level, spend your Rings to Rebirth. Use the Chaos Orbs and Rings you earn to hatch better pets, which in turn help you level up and Rebirth even faster.

It’s a cycle of continuous improvement. Keep grinding, focus on completing events, and soon you’ll be leaving everyone else in the dust. Now get out there and get running!
