Diamond

Tap anywhere to earn Coins, hatch eggs for pets that multiply those Coins, and rebirth to turn the Coin wallet into Gems plus a permanent tap multiplier. Gems buy the skill tree. Islands open by portal fees or by jumping up to them.

No. Rebirth spends the Coins you are holding. Pets, pet tiers, inventory, unlocked islands, shiny stars, and purchased gem upgrades stay.

No published reward-code string was found for this experience. The shop has a Support a Creator field for partner credit on Robux purchases. That field is not a free-item code, and codes from the original Tap Simulator belong to a different game.

The public game description says trading is coming soon. Separate play notes say trading was on briefly and then turned off to fix duplication and interface bugs. Treat the current listing line as the status until the developers say it is open.
