Gym Star Simulator just got a spooky Halloween update, and it adds a fresh reason to log in, grind, and check the shop. If you’re wondering what the event includes, how the new eggs work, and which redeemable codes can help you progress faster, this guide covers the key player-facing details.

The update centers on Halloween-themed content, special eggs, a new belt, and a temporary boost weekend. It also lines up with the game’s usual progression loop: train muscles, earn cash, improve pets, and push toward stronger competition results.

What’s new in the Halloween update?

From the update shown in-game, the main additions include:

New contentWhat it means for players
Halloween eventThe gym gets a darker seasonal look and themed event content
Mega boost weekendA temporary 4x muscle growth boost
New special eggsTwo Halloween eggs in the shop
New Halloween beltA seasonal belt tied to candy progress
Buff to exclusive petsExclusive pets get stronger value during the update

The exact value of every new item can depend on your current build and progression, so it’s worth checking the shop and your pet loadout after the update lands.

Halloween eggs in Gym Star Simulator

The Halloween event includes two new special eggs. These are the main seasonal draw if you want event pets or you’re chasing a stronger setup for training and competition.

Based on the update gameplay:

  • The eggs are available in the shop during the event.
  • You can hatch themed pets from them.
  • Some pulls may be duplicates, which can still matter if crafting is available for your pet inventory.
  • The video example showed Halloween-themed pet names like Spidey and a sand-witch style pet.

Because egg results depend on luck, your best approach is to decide how much currency or Robux you want to spend before opening them. Seasonal eggs can be tempting, but they’re usually most useful if they improve your current training pace right away.

Should you spend Robux on Halloween eggs?

That depends on your goals:

If you want...Consider doing this
Faster early progressUse eggs only if they give a clear boost over your current pets
Collection valueOpen the Halloween eggs while the event is active
EfficiencyCompare pet stats before spending more on extra hatches
Long-term valuePrioritize pets that help your current training and competition route

If you’re not sure, it’s smart to hatch a small batch first and see whether the seasonal pets are strong enough to replace what you already use.

New Halloween belt and candies

The update also introduces a Halloween belt, and it appears tied to candy collection. In the footage, the belt could be earned with candies rather than only bought outright, which makes it a major event goal for grinders.

Important takeaway: the event belt looks like a progression reward, not just a cosmetic item.

Event itemHow players seem to get it
Halloween beltEarned or bought with candies during the event
CandiesCollected through event play and ongoing training

If you want the belt, focus on:

  1. Logging in during the event window
  2. Training consistently
  3. Checking event rewards and candy totals often
  4. Spending event currency only after comparing the reward to your current gear

How the boost weekend helps

The Halloween update includes a mega boost weekend with 4x muscle growth. That’s a huge advantage if you’re trying to rank up or unlock a new area.

During a boost weekend, your best play is usually to:

  • Train the muscle type that gives you the best return
  • Use any consumables you already have
  • Refill energy or stamina when needed
  • Save repetitive grinding for the boosted period

This is especially helpful if you’re trying to catch up after spending currency on eggs or pets.

Here’s a simple checklist to follow after joining the Halloween update:

GoalWhat to check
Seasonal rewardsOpen the event shop and look for the Halloween belt
Pet upgradesCompare the new eggs to your current best pets

Best update strategy for new and returning players

If you’re jumping into the Halloween update from scratch, your first priority should be progression speed, not spending.

A simple approach:

  • Claim free gifts
  • Redeem codes first
  • Train the muscle that gives the best gains
  • Use pets that improve your current grind
  • Save major spending for the items that noticeably help your build

Returning players may want to focus on the event belt and the special eggs first, since seasonal content can be time-limited.
