Quick answer
What to do
Set a cash limit before rolling, compare the pet information shown in your server, and keep enough resources to protect anything valuable you obtain.
1. Set a limit
Choose the most cash you are willing to spend before the first roll.
2. Read the in-game result
Use the rarity, income, or other values currently displayed by the game.
3. Protect the result
Move a valuable pet into a defensible setup before taking another risk.
