Throw Sim rebirth guide

Rebirth trades your current Strength and unlocked worlds for a permanent multiplier. It is the main way to reach the late worlds.

You keep

Wins
Pets and pet locks
Balls and trails
Game passes
Upgrade station upgrades and paid world tolls

You lose

Strength (back to zero)
Unlocked worlds: you go back to Candy Coast and re-open each portal

What rebirth gives you

Strength multiplier. Rebirths 1 to 15 follow a steep curve: (1 + 0.5 x rebirths) x 1.3^rebirths. That is x1.95 after 1 rebirth, about x13 after 5 and about x83 after 10. After 15 rebirths, each extra rebirth multiplies it by 1.15.
Wins multiplier. Every rebirth adds +10% Wins (x2 after 10 rebirths).
Late worlds. Worlds 11 to 15 need lifetime rebirths: Bubblegum Bay 20, Toy Factory 23, Dino Valley 26, Pirate Cove 29, Mushroom Grove 32.

Costs double each rebirth plus a growing step, and grow 2.6x per rebirth after 20 rebirths. Players whose saves are from before the worlds 11 to 15 update keep at least the multiplier the old curve gave them. Multipliers stack with pets, trails and passes.

When should I rebirth?

The first rebirth needs 60M Strength, which you usually reach around Neon Metro. Rebirth as soon as you can afford it and you have bought what you want with your Wins, because Wins are kept but Strength is not.
