2026 Strategies for Maximizing Halloween Event Rewards
To help you make the most of this limited-time event, I’ve compiled some pro strategies based on my experience with previous Build a Zoo events and the new features introduced in Update 29.
Beginner Strategies
If you’re new to Build a Zoo or joining specifically for the Halloween event, here’s where to start:
- Redeem All Active Codes First: Before doing anything else, redeem all the active codes listed above. This will give you a solid foundation of eggs and cash to work with.
- Focus on Event Challenges: Prioritize completing Halloween event challenges over regular gameplay. These offer exclusive rewards that won’t be available after the event ends.
- Start with Basic Halloween Decorations: Begin by placing the most affordable Halloween decorations to get into the festive spirit and unlock additional challenges.
- Level Up Your Big Pets: With the new level cap increase, focus on leveling your strongest pets first to take advantage of the extended progression system.
Advanced Strategies
For experienced players looking to maximize their Halloween event experience:
- Strategic Pet Following: Use the new Pet Following feature to your advantage by having your highest-level pets accompany you during challenges and competitions.
- Optimize Zoo Layout for Halloween: Rearrange your zoo to create spooky pathways and themed areas that maximize both aesthetics and efficiency.
- Focus on Limited-Time Content: Prioritize collecting event-exclusive pets and items over regular content, as these will become unavailable after November 5th.
- Participate in Admin Abuse Events: Don’t miss the pre-update Admin Abuse Event, as these often feature unique opportunities to obtain rare items and currency.
Resource Management Tips
Managing your resources effectively during the Halloween event is crucial:
- Save Event Currency: Don’t spend your Halloween event currency immediately. Wait until you’ve seen all available rewards to make informed purchasing decisions.
- Balance Egg Hatching: While it’s tempting to hatch all your new eggs at once, consider spacing them out to maintain a steady progression throughout the event.
- Invest in Multipliers: If possible, purchase or earn multipliers that will increase your rewards from Halloween challenges and activities.
Common Mistakes to Avoid
Based on my experience with previous Build a Zoo events, here are some common mistakes players make during Halloween events and how to avoid them:
Missing the Admin Abuse Event
Many players don’t realize the Admin Abuse Event happens before the main update and miss out on exclusive rewards. Solution: Set a reminder for one hour before the official update time (2:00 AM PDT on October 18th) to participate in this special event.
Not Redeeming Codes Promptly
Codes can expire at any time, and some players wait too long to redeem them. Solution: Redeem all active codes as soon as possible, even if you don’t plan to use the rewards immediately.
Overspending on Early Decorations
Some players spend all their resources on the first Halloween decorations they see, only to find better options later. Solution: Browse all available Halloween decorations before making purchases to ensure you’re getting the best value.
Ignoring the Pet Following Feature
The new Pet Following feature is more than just cosmetic—it can provide strategic advantages. Solution: Experiment with different pets following you to discover which combinations work best for your playstyle.
Platform-Specific Information
The Build a Zoo Halloween Update is available across all platforms where Roblox is accessible, but there are some platform-specific considerations to keep in mind:
PC/Mac Players
- Performance: Take advantage of the optimization updates by ensuring your graphics drivers are up to date
- Controls: The Pet Following feature works best with mouse and keyboard controls for precise navigation
- Multi-monitor: If using multiple monitors, consider dedicating one screen to your zoo overview for better management
Mobile Players (iOS/Android)
