•Hatch Pets Early: Use wins to buy eggs and hatch pets, as they provide permanent boosts to your training gains. Prioritize pets with higher multipliers to maximize your progress.
•Save for Rebirths: Accumulate wins to purchase rebirths, which reset progress but grant access to new worlds with better equipment. Rebirths also provide multipliers that speed up future training.
•Check for Codes Regularly: Redeem codes like “Welcome” and “Pet” as soon as possible, as they expire quickly and offer free wins and pets. Follow the game’s Discord or Roblox group to stay updated on new code drops.
