How rebirth works
After spawning, the Rebirth icon sits on the left side of the screen (per the Sportskeeda guide published July 25, 2026). Each of the 16 tiers requires a Cash pile plus a specific pair of pets, and claiming the tier pays the rewards permanently.
Every tier grants the same shape of reward: a Luck multiplier, +2 max pet slots, +3 defense blocks, and at least one gear item. The Luck line grows from 2x at tier 1 to 208x at tier 16, which is why long-term players roll dramatically better species than new accounts.
Required pets must stay in your base until the tier is claimed. Selling a requirement pet mid-run stalls the ladder no matter how much Cash is banked.
The early ladder (tiers 1-8)
Tiers 1-8 run from 50,000 Cash to 10,000,000 and ask for accessible species: Cat + Chicken, Bunny + Bat, Owl + Llama, Zebra + Elephant, Lion + Stegosaurus, YiQi + Mammoth, Velociraptor + Azhdarchid, and Gargoyle Bat + Cockatrice.
Gear rewards in this band are foundational: Steel Bat and Speed Coil (tier 1), Gravity Coil (tier 2), Stone Bat (tier 3), Cobalt Bat (tier 4), Dual Coil (tier 5), Grapple Hook (tier 6), Obsidian Bat (tier 7), and Bear Trap (tier 8).
Notice the design: by tier 8 you own both a raid kit (bats, coils, grapnel) and a defense tool (Bear Trap). The ladder deliberately equips both sides of the loop.
The late ladder (tiers 9-16)
Tiers 9-16 climb from 25,000,000 to 10 quadrillion Cash with mythic pairs: Sphinx + Pegasus (tier 9), Roc + Hydra (tier 10), Qilin + Simurgh (tier 11), Dragon + Unicorn (tier 12), Golden Kitsune + Gold Unicorn (tier 13), Gold Dragon + Gnome (tier 14), Fairy + Mermaid (tier 15).
Rewards scale with them: Crystal Bat and Juggernaut (tier 9), Golden Bat (tier 10), Shrink Potion (tier 11), Goku Bat and Invisibility Cloak (tier 12), Sky Bat and Body Swap Potion (tier 13), Galaxy Bat and Rage Bat (tier 14), Hacker Bat, Ban Hammer and Flashbang (tier 15).
Tier 16 is the capstone at 10 quadrillion Cash: 208x Luck, the Demon Bat, TNT, a Magnet, and a Sniper Rifle - the heaviest documented toolkit in the game.
How to plan a rebirth run
Identify the next tier's pair and protect those two pets immediately - deepest base slot, no selling, no raid-carry. Everything else in the session routes Cash toward the requirement.
Bank surplus into permanent multipliers first. Because each tier raises Luck, slots, and defense at once, reaching the next rung usually outvalues any single pet purchase in the same price range.
Claim in a private server if timing anxiety is a factor; the claim works the same and nothing public can interrupt it. Then re-run the defense audit, because the new tier's gear changes both your attack options and the ones aimed at you.
