The loop
Pet Simulator 99 is a numbers-go-up game. You break objects in areas to earn coins, use coins to hatch eggs that drop pets, equip the highest-multiplier pets to break stronger objects faster, unlock new areas, and repeat at a larger scale. Understanding this loop matters because every "should I buy X" decision flows from it.
The single most useful framing: your pet team's total damage multiplier is the throttle on every other progression curve. If your damage doubles, your area unlock speed doubles, your egg rotation speed doubles, your gem income doubles, your Diamond income doubles. Optimizing pets early pays back exponentially. Almost every bad decision a new player makes is some version of spending a resource on a thing that does not raise that one number.
Diamonds, gems, and coins are not the same
PS99 runs three currencies and they reward completely different behavior. Confusing them is the most expensive rookie error.
| Currency | How you earn it | What it buys | Spend it on |
|---|---|---|---|
| Coins | Breaking objects in your current area | Standard eggs, area progress | Freely; coins are local and disposable |
| Gems | Drops, chests, fruit, mastery | Lucky boosts, upgrades, some eggs | Lucky boosts before big egg sessions |
| Diamonds | Diamond zones, codes, rare drops, trading | Diamond eggs, premium hatches, Huges | Hoard early; never on the basic Diamond egg |
Coins inflate fast and reset on rebirth, so emptying your coin balance is fine. Diamonds are slow, permanent, and the backbone of the trade economy, so treat them like real money. The first active code, DIAMONDS25, hands you 25,000 of them for free; that is your early war chest, not pocket change to dump on the first Diamond egg you see.
What to do in your first hour
- Break objects in the first area until you can afford the second egg ($500 or so). Don't waste coins on the first egg; its pets are obsolete within an hour.
- Hatch the second egg until you have 3 of its best pet. Equip 3 of them.
- Move to the next area. Break, hatch, equip, repeat.
- Redeem every active code before you do anything else (Esc → Settings → codes box). DIAMONDS25 and RELEASE_ANNIV cost nothing and give you Diamonds plus 10 Lucky Boost.
After about an hour you'll reach the first major Diamond zone. Diamonds don't earn fast but they're permanent. Don't blow them on the basic Diamond egg. Save until you can afford a tier-3 or tier-4 Diamond egg, which has Huge-tier pets in its table. A single Huge from one of those eggs is worth more than every coin pet you will ever hatch combined.
The areas to push to
The early "checkpoint" areas worth aiming for:
- Spawn → Beach (first 30 minutes): basic pet variety.
- Beach → Cave: first non-trivial damage requirement.
- Cave → Frozen Tundra: first meaningful pet upgrade tier.
- Frozen Tundra → Tech: where Huge pulls become realistic.
- Tech → Space: gateway to mid-game.
Each area approximately doubles your damage requirement. Don't try to skip ahead; you'll waste coins on inefficient pet hatches if you're not in the right area yet. The right move at every wall is to clear the current egg first. An area's egg is tuned to break that area's objects, and three copies of its best pet will carry you to the next gate more reliably than gambling on a higher egg you cannot yet afford to roll repeatedly.
A practical pacing note: do not buy the next area the second it unlocks. Buy it when your damage is high enough that its objects pop in a second or two. Walking into an area where every object takes ten seconds means your coin-per-minute drops, and coin-per-minute is the only thing funding your next pets.
Best pets are about stats, not rarity
PS99 ranks pets internally. The game shows a rarity tier (Common, Rare, Epic, Legendary, Mythic) but the actual usefulness is on the per-pet damage stat. A high-stat Legendary in an area's appropriate range outperforms a low-stat Mythic from a previous area. The pet's stats screen is the source of truth.
Don't equip a pet just because it's rare. Equip the best stats you have for the current area. Two mechanics make a single pet hit harder than its base number:
- Best pets / shiny upgrades. Combining duplicates upgrades a pet's tier, which multiplies its damage. Five of the same pet fused is worth far more than five equipped separately, so once your team slots are full, fuse the overflow rather than hoarding it.
- Enchants. Slotting enchants onto a pet adds damage, Lucky, or other modifiers. An enchanted mid-tier pet routinely beats an un-enchanted higher-tier one.
For where any specific pet sits in the pecking order, the PS99 pet tier list ranks current pets by usable damage and trade weight, and the pet database shows each one's stats and community value.
Rebirth timing
Rebirths reset your area progress in exchange for a permanent damage multiplier. The first rebirth is unlocked early; the multiplier is small but the bonus is permanent. Rebirth as soon as the option appears and again whenever you've reached the wall you can't break.
A common new-player mistake is hoarding rebirths thinking they'll be more valuable later. They aren't — they compound. Take them as soon as you reach the wall. The full cadence, the rebirth shop priorities, and the two situations where you should not rebirth are covered in the rebirth strategy guide.
Codes
Apply every active code in your first session. Diamonds and Lucky boosts are most useful early when your pull rates are starving for variance. The two currently live are DIAMONDS25 (25,000 Diamonds) and RELEASE_ANNIV (10 Lucky Boost). Codes expire, so check the page before each session rather than trusting an old list.
What to ignore
- Trading until you're 5+ hours in. Your pets aren't valuable to others yet, and a new account is exactly who scammers target.
- The cosmetic shop. Spend gems on Lucky boosts, not skins, for the first ten hours.
- Daily login wheels with vanity rewards. Spin them, but don't structure your play around them.
- Group / partnership invites in random servers. They're rarely legitimate.
Common mistakes
- Dumping Diamonds on the basic Diamond egg. Its table is filler. Save for a tier-3 or tier-4 Diamond egg with Huges in it.
- Equipping by rarity color instead of by damage number. The stats screen is the truth; a glowing Mythic from two areas ago is dead weight.
- Hoarding duplicate pets instead of fusing them. Overflow copies do nothing in your inventory. Fuse them into best-pet upgrades.
- Buying a new area before your damage can clear it quickly. You tank your coin-per-minute and starve the rest of your progression.
- Opening eggs with no Lucky stacked. A handful of free Lucky Boost from codes is wasted if you fire it at common eggs instead of saving it for a real hatch session.
When you hit your first wall
Every PS99 player hits a wall. The fix order:
- Rebirth.
- Check if you're missing equipped pet slots (each slot has to be unlocked).
- Buy the next-tier pet egg even if you have spare coins.
- Make sure your highest-tier pets are equipped (the game won't auto-equip).
- Use Lucky boosts before opening eggs.
Almost every wall is one of these five.
FAQ
Should I spend Robux as a beginner?
Only on permanent value. A Lucky gamepass or extra equip slots compound across the whole account; a one-time cosmetic or a small Diamond pack does not. If you spend nothing, you can still reach mid-game on codes and grinding alone; Robux buys speed, not access.
How long until I can hatch a Huge?
Realistically once you reach the Tech area and can afford to roll a tier-3 or tier-4 Diamond egg repeatedly, usually a few hours of focused play. The early farmable Huge eggs sit around 1-in-100 to 1-in-1,000, so a stacked Lucky session gives you a genuine shot. The full method is in the Huge hunting guide.
Do I need to trade to progress?
No. Trading accelerates an account but is not required to clear areas. Damage does that, and damage comes from pets and rebirths. Hold off on trading until you understand fair value, which you can check on the trade value calculator. A new player who trades blind usually gives away more than they gain.
What does "Huge" actually mean?
A Huge is a giant variant of a base pet, far rarer than the normal form and the main trading currency inside PS99. The glossary defines it and the other terms you'll see thrown around in trade chat. Titanics are an even rarer step above Huges; you will not see those for a long while.
