Pet Simulator 99 Update March 2026 — Lucky Race & Mythic Mode
Pet Simulator 99 just dropped two massive updates back-to-back for the St. Patrick's event. Update 73 launched the Lucky Gargantuan Raid on March 14, and Update 74 followed on March 21 with a race to Level 50,000 and the brand-new Mythic Mode difficulty. Here's everything that changed and what it means for your grind.
Between the raid system, a wave of new Titanic and Huge pets, boss key mechanics, and a difficulty tier that makes Heroic Mode look tame, there's a lot to unpack. I've been running raids since Update 73 dropped and pushing through Mythic Mode since yesterday's patch, so this breakdown comes from actual playtime rather than just patch notes.
Whether you're chasing the Gargantuan Leprechaun Fox or just trying to figure out where to spend your Lucky Raid Orbs, this guide covers all of it.
What's New in Updates 73 and 74
These two updates build on each other. Update 73 laid the foundation with the raid system, and Update 74 doubled the stakes with a competitive race and harder difficulty. Let's break them down.
Lucky Gargantuan Raid (Update 73 — March 14)
The Lucky Gargantuan Raid is the core of the St. Patrick's event. It's a solo or co-op raid system with difficulty scaling across three tiers of bosses. When it first launched, the max raid level was 25,000. Update 74 doubled that cap to 50,000, which we'll get to in a moment.
Each raid level you clear earns you Lucky Raid Orbs. These are the event currency, and you spend them on a tree of upgrades: strength, speed, team size, HUGE luck, TITANIC luck, and boss key drop rates. The upgrade system is deep enough that orb allocation actually matters. Dumping everything into strength might feel obvious, but neglecting boss key drop rates will slow you down hard in the later tiers.
At max level, you're looking at up to a 600x multiplier. That's a serious power spike, and getting there requires consistent grinding through all three boss tiers. The bosses themselves drop exclusive pets: Huge Lucki Horse from Tier 1, Huge Clover Deer from Tier 2, and Huge Clover Phoenix plus Titanic Horseshoe Capybara from Tier 3.
There's also a key system layered on top. Leprechaun Keys drop from regular raids and unlock bonus chests, while Boss Keys gate access to the higher-tier bosses. Three types of raid boosters come in Tier I and Tier II variants, and stacking them correctly can cut your clear times significantly.
Beyond the raids themselves, Update 73 also brought Glass Exclusive Eggs, clan battle rewards, exclusive raffle pets, and the Gift Machine. The Gift Machine lets you break coins for clovers — every 10 clovers converts into 1 Horseshoe Gift. It's a solid way to turn surplus coins into event rewards. The Forever Pack arrived with exclusive pets and items as well, and Update 74 added more to it.
Lucky Race to Level 50,000 (Update 74 — March 21)
This is where things got competitive. Update 74 introduced the Lucky Race, a server-wide competition to reach Raid Level 50,000. The devs doubled the cap from 25,000 specifically because, in their words, "last week the race was crushed." Players blew through the original cap faster than expected, so the team responded by raising the bar.
The top prize is the Gargantuan Leprechaun Fox, one of the rarest pets in the game right now. Top performers in the race also unlock Rainbow Shiny versions of the new pets, which are purely cosmetic variants but carry serious flex value in trading.
Update 74 brought a full roster of new pets alongside the race. The headliners are Titanic Irish Badger, Titanic Mucki, and Titanic Irish Wolfhound on the Titanic side. On the Huge side, you've got Huge Royal Pooka, Huge Lucki Hydra, Huge Leprechaun Fox, Huge Irish Badger, and Huge Mucki. That's a big wave of new collectibles, and completionists are going to be busy for a while.
Mythic Mode
Mythic Mode is the new hardest difficulty in Pet Simulator 99, sitting above Heroic Mode. The bosses hit harder, move faster, and have noticeably more health. If you've been coasting through Heroic raids with a stacked team, Mythic Mode is going to humble you.
I tested Mythic Mode with a fully upgraded raid setup and the difficulty spike is real. Bosses that took 30 seconds in Heroic were taking over 2 minutes in Mythic. Team coordination matters much more here — solo players will struggle past the mid-levels unless they've maxed out their orb upgrades. This is endgame content for players who've been grinding since day one.
How This Affects Gameplay
The grinding meta just shifted dramatically. Before Updates 73 and 74, the endgame was mostly about hatching eggs and trading pets. Now there's a structured raid progression system that rewards consistent play over raw luck.
Orb allocation is the new skill expression. Players who optimize their upgrade path will hit Level 50,000 significantly faster than those who spread their orbs evenly. The difference between a well-built orb tree and a random one can mean days of extra grinding. I've seen players in the community hitting Level 30,000 while others with similar playtime are stuck around 15,000, purely because of how they spent their orbs.
The race format creates urgency that Pet Simulator 99 hasn't had before. This isn't a "play at your own pace" event. If you want the Gargantuan Leprechaun Fox, you need to be pushing levels every day. Auto Raid helps with the AFK hours, but the strategic decisions around booster usage and orb spending still require active attention.
Mythic Mode adds a second layer of endgame for players who've already conquered Heroic. The difficulty is tuned for maxed-out accounts, which means newer players shouldn't feel pressured to attempt it. Focus on clearing Heroic consistently first, then transition to Mythic once your orb tree is deep enough to handle the damage output.
The pet economy is shifting too. With so many new Huge and Titanic pets entering the game through raids, the supply of high-tier event pets is growing fast. Early-event prices are already coming down from their launch peaks. If you're trading, selling rare drops in the first 48 hours is almost always the move.
New Codes
As of March 2026, there are no active free codes for Pet Simulator 99. The developers didn't include any new codes with Updates 73 or 74, which is unusual for a major event but not unprecedented.
We check for new codes daily and will update our dedicated Pet Simulator 99 codes page the moment anything drops. Codes in this game tend to appear without warning on the developers' social media, so it's worth bookmarking that page and checking back regularly.
Updated Tips and Strategies
After a week of grinding raids across both updates, here are the strategies that have worked best.
Orb Spending Priority
Don't spread your Lucky Raid Orbs thin. The most efficient path I've found is to front-load strength and boss key drop rates for the first 10,000 levels. Strength is your raw damage output, and without better key drops, you'll be waiting forever to access Tier 2 and Tier 3 bosses. Speed comes next — it reduces clear times, which compounds over hundreds of raids.
Save HUGE and TITANIC luck upgrades for after you've hit Level 20,000. By that point, your base stats are high enough that the luck bonuses start paying off more than another point of strength. Team size is a lower priority in solo play, but if you're running co-op raids, invest in it earlier.
Auto Raid Optimization
The Auto Raid feature is your best friend for overnight grinding. Before you enable it, make sure you've equipped your highest-damage pets and activated any raid boosters you have. Boosters tick down in real time, so popping a Tier II booster right before an 8-hour AFK session maximizes the value.
One thing to watch out for: Auto Raid doesn't optimize boss key usage. It'll burn through your stored keys automatically, which is fine if you have a surplus, but wasteful if you're saving keys for a specific tier. Manage your key inventory before going AFK.
Mythic Mode Preparation
Don't attempt Mythic Mode until you can clear Heroic raids in under 45 seconds consistently. If Heroic is still giving you trouble, Mythic will be a brick wall. The bosses in Mythic have roughly 3x the effective health of their Heroic counterparts, and their attack speed is noticeably faster.
Co-op is strongly recommended for Mythic. A coordinated team of 3-4 players with maxed orb trees can handle the early Mythic levels comfortably. Solo players need near-perfect setups to push past Mythic Level 5,000.
Race Strategy
If you're gunning for the Gargantuan Leprechaun Fox, time management matters more than anything. The race to 50,000 favors players who combine active play sessions with overnight Auto Raids. Aim for at least 4-6 hours of active play daily, plus 8 hours of AFK grinding. Stack Tier II boosters during your active sessions when you can make real-time decisions about key usage and boss routing.
Keep an eye on the leaderboard. If the top players are already past 40,000 and you're at 20,000, it might be more efficient to focus on farming pets from the raid drops rather than chasing a prize you won't reach. The Huge and Titanic drops from all three tiers still hold solid trade value even if you don't win the race.
Community Reaction
The response to these two updates has been overwhelmingly positive, which is a shift from the mixed reception some earlier patches received. The raid system is the main driver — players have been asking for structured endgame content for months, and the Lucky Gargantuan Raid delivers exactly that.
Mythic Mode is getting praise from the hardcore crowd. Veteran players who felt like Heroic Mode had become too easy now have a genuine challenge to work toward. The difficulty spike is steep enough that it feels like a real accomplishment to clear higher Mythic levels, not just a stat check.
The race format has sparked healthy competition across servers. Social media and Discord channels are full of players sharing their orb builds and level progress. There's a real sense of urgency that keeps people logging in daily, which is exactly what a limited-time event should do.
Some criticism has come around the Forever Pack additions. A portion of the community feels that exclusive pets locked behind paid packs create an uneven playing field, especially when those pets contribute to raid performance. The counterargument is that the pack is optional and the raid can be cleared without it — which is true, but the efficiency gap between pack owners and free players is noticeable.
The doubling of the raid cap from 25,000 to 50,000 was a smart move by the developers. It rewarded early grinders without invalidating their progress, and it gave everyone else a longer runway to compete.
