Rebirth is Pet Simulator 99's prestige ladder, but a friendly one: modern rebirths hand out unlocks and reward bundles without wiping your progression. Each step opens something new, and two of them (Rebirth 3's Secret Keys and Rebirth 4's Ultimates, Mastery, and Tech World rocketship) reshape how the game plays.

What rebirthing costs and keeps
Unlike classic prestige systems, current rebirths do not reset your progression: they are gates you buy through with accumulated progress, each granting permanent boosts, features, and a bundle of items. That makes the only real question when, not whether.
The steps that matter most
- Rebirth 3 opens Secret Key usage, the ticket into the game's hidden rooms.
- Rebirth 4 is the big unlock: Ultimates, the Mastery system, and rocketship access to Tech World all at once. Most guides treat reaching it as the end of the early game.
- Rebirth 7 permanently improves ultimate charging and XP, the sleeper perk for anyone leaning on ultimates.
- Rebirth 9 is the current cap; after it, progression continues through Mastery, enchants, and pets rather than more rebirths.
Each card lists the full unlock and reward bundle for its step, so you can see exactly what the next rebirth buys before committing the grind.
