Pet Simulator 99 (PS99) is the successor to Pet Simulator X on Roblox. It keeps the pet-collection grind but adds more structured worlds, egg tiers, breakable zones, and machine-based upgrades. You earn coins and diamonds by breaking objects in each area, spend currency on eggs, hatch pets to boost damage and luck, then push into harder zones and events. Trading, huge pets, and seasonal content add more UI layers than the older game. Many actions still come down to repeated clicks on fixed Hatch or Open buttons, tap-to-break zones, or machine prompts. This guide explains how PS99 hatching and farming work, where clicking fits in, recommended autoclicker settings, common mistakes, and FAQ, with clear caveats about terms of service.
PS99 expands the classic pet-sim loop into distinct areas and systems:
Compared to PSX, PS99 puts more emphasis on zone-based farming, structured egg tiers, and machine menus. Clicking is still central: you break, hatch, and interact with shop and upgrade UIs throughout a session.
Clicking shows up in several routine tasks:
When a button stays in one place (Hatch, Open, a machine confirm), Mouse Position is the right target mode. For a large break zone where any click in the region counts, Click Area can spread clicks inside that region. PS99 often gates hatch animations and break respawns, so maximum CPS rarely helps.
Target mode: Use Mouse Position for Hatch, Open, and fixed machine buttons. Use Click Area only for large break or tap zones where the game accepts clicks anywhere in the region. See How to use mouse target mode on Roblox for setup.
Click interval: Start around 200-600 ms with a small random deviation. Test what PS99 actually accepts in your current zone; hatch animations and break cooldowns may cap real throughput before your autoclicker does.
Hotkey: Use a start/stop hotkey so you only click when your cursor is on the correct button or zone. Stop immediately when trade windows, teleport menus, or egg result screens open.
If your autoclicker supports sequences, you can chain steps for repetitive PS99 grinds: e.g. click Hatch several times, wait for the animation window, click a collect or confirm button, move to a break zone step, then repeat. Each step can use Mouse Position (move the cursor before that step) or a fixed Click Area for a large break region. A sequence editor overlay helps confirm each step lands on the right UI so you do not click through into the wrong world menu or trade prompt.
Roblox and Pet Simulator 99 have terms of service that can restrict automation. Using an autoclicker may violate those rules and can result in account action. Use at your own risk; this guide is for educational purposes only.
For most players, Mouse Position on the Hatch or Open button with a 200-600 ms interval and small random deviation is a solid starting point. Add a hotkey so you can stop when menus open. Switch to Click Area only when you are farming a large break zone that accepts clicks anywhere in the region.
Use Mouse Position for fixed UI: Hatch, Open, machine confirms, and vendor buttons. Use Click Area when you are breaking objects in a wide tap zone and the game does not require pixel-perfect aim. If a button moves when a menu opens, stop the clicker and reposition before restarting.
Roblox and PS99 can restrict automation under their terms of service. Reports, logging, or anti-cheat systems may flag unnatural click patterns. This guide does not guarantee safety; use at your own risk and prefer moderate, human-like intervals over constant maximum speed.
Both games use Hatch/Open clicks and break-to-farm loops, but PS99 adds more zone-specific machines, structured egg tiers, and trade-heavy UI. PSX players often reuse the same habits (Mouse Position on Hatch, moderate intervals), but PS99 needs more attention to area changes, machine menus, and stopping during trades.
