Updated November 4, 2026. Pet Simulator 99’s Halloween Games are live, but players should not confuse the different deadlines. BIG Games has confirmed that the individual Halloween leaderboard stops scoring on November 6, 2026, while Halloween Games pets remain untradeable until November 7, 2026. The developer has not announced one universal shutdown date for every Halloween activity in the Update 100 announcement.
Quick answer: Finish your leaderboard push before November 6. If you are waiting to trade Halloween Games pets, the stated restriction lasts until November 7. Treat those as two separate dates: the first is a competition scoring deadline, and the second is a trading restriction—not confirmation that the whole Halloween event ends on that day.
Pet Simulator 99 Halloween deadline calendar
| Date | What happens | What players should know |
|---|---|---|
| October 31, 2026 | Update 100: Halloween Games launched | The new minigames, Haunted Farm, Forge, Season Pass and contests arrived. |
| November 6, 2026 | Halloween individual leaderboard scoring ends | Your final Treat score and rank determine the leaderboard reward tier. |
| November 6, 2026 | Ender Clan Battle's six-day window reaches its listed end date | Clan rewards use a separate ranking system from the individual leaderboard. |
| November 7, 2026 | Halloween Games pets become tradeable | This is the end of the stated trading restriction, not a confirmed event shutdown. |
BIG Games' Update 100 announcement explicitly gives November 6 as the individual leaderboard scoring deadline and says Halloween Games pets stay untradeable until November 7. The BIG Games Index separately lists the Halloween Games Clan Battle as running October 31–November 6. Neither source gives a precise hour for the November 6 close, so check the in-game countdown rather than relying on a guessed timezone conversion.
What ends on November 6?
Individual Halloween leaderboard scoring
The Halloween Games leaderboard counts Treats earned in the event. When scoring ends on November 6, your final position determines which reward you qualify for. A temporary position during the event is not a guaranteed prize: other players can continue earning Treats and move ahead before the scoring window closes.
BIG Games lists these individual leaderboard reward bands:
| Final rank | Reward |
|---|---|
| 1–3 | Gargantuan Butler Penguin |
| 4–6 | Rainbow Shiny Titanic Trick Or Treat Hippo |
| 7–13 | Golden Shiny Titanic Trick Or Treat Hippo |
| 14–103 | Rainbow Titanic Trick Or Treat Hippo |
| 104–253 | Shiny Titanic Trick Or Treat Hippo |
| 254–503 | Golden Titanic Trick Or Treat Hippo |
| 504–1,003 | Titanic Trick Or Treat Hippo |
| 1,004–10,000 | Huge Frankenpet Monkey |
Pay attention to the boundaries. Finishing 1,003rd qualifies for the standard Titanic Trick Or Treat Hippo, while 1,004th falls into the Huge Frankenpet Monkey tier. The same principle applies at the top: only the first three places receive the Gargantuan Butler Penguin.
What happens to the Ender Clan Battle?
The Ender Clan Battle is a separate competition. BIG Games says it runs for six days, and the BIG Games Index lists the Halloween Games Clan Battle from October 31 through November 6, 2026. Its rewards include Gargantuan Warrior Wolf, Titanic Ender Goat variants and Huge Ender Bunny, along with clan cosmetics and medals.
Do not mix up the two leaderboards. The individual Halloween leaderboard awards Gargantuan Butler Penguin and Titanic Trick Or Treat Hippo variants. The Ender Clan Battle uses clan placement and has its own reward ladder. BIG Games also says every member of a qualifying clan receives that clan's prize.
Free Halloween rewards you can still work toward
Update 100 offers several reward routes beyond leaderboard placement. If you are not close to a high rank, these activities may be more realistic targets before the deadlines.
- Huge Guard Bat: Reach Tier 4 of the Halloween Season Pass. Complete event quests to earn Season Tokens and progress through the pass.
- Huge Neon Skeleton Dino: Open Midnight Gifts earned from Halloween Games matches. BIG Games says winning a match gives a large stack, with additional gifts for strong placements.
- Huge Guard Rhino: Hatch the egg in the final zone of the Haunted Farm.
- Forge Huge pets: The Halloween Forge can brew event pets into Huge Guard Elephant, Huge Trick Or Treat Piggy and Huge Bedsheet Giraffe.
- Spirit Shards: Earn these by surviving the games and use them to improve luck at the Forge.
The currencies have different jobs. Treats are used for six upgrade tracks and count toward the individual leaderboard. Candy Coins unlock Haunted Farm zones and eggs. Spirit Shards improve Forge luck. Keeping them separate helps you spend your playtime on the reward you actually want.
Does the whole Pet Simulator 99 Halloween event end on November 7?
That has not been confirmed by the official Update 100 announcement. November 7 is the date BIG Games gives for the end of the Halloween Games pets' untradeable restriction. It does not say that every Halloween activity, reward track, shop offer or PSX Classic Halloween feature shuts down at that time.
For now, use November 6 as the confirmed leaderboard scoring deadline and November 7 as the stated trading date. If BIG Games posts a separate event-removal schedule, that announcement should take priority. Until then, avoid treating an unannounced global end date as fact.
What should players do before the deadline?
- Check your current individual leaderboard rank and decide which reward cutoff you are realistically targeting.
- Play Halloween Games for Treats and Midnight Gifts; survival time and placement affect what you earn.
- Check your clan's Ender Clan Battle position separately from your individual rank.
- Complete Season Pass quests if you still want the free Huge Guard Bat at Tier 4.
- Use Candy Coins to unlock Haunted Farm zones if you are still working toward the final egg and Huge Guard Rhino.
- Do not plan trades for Halloween Games pets before November 7; the official restriction is still in place until then.
