Decision rule
Measure before you rank
A pass can be excellent for one loop and irrelevant for another. Measure Damage per action, time per clear, Wins per clear and whether survival ends the fight. Then choose the smallest change that improves the repeated wall. The calculator makes the Wins and training parts visible without needing a hidden formula.
FAQ
Tier-list questions
Is there a verified pet tier list?
Not yet. A reliable ranking needs a current pet roster, effects, acquisition details and sourceable comparisons.
What is the best first upgrade?
Fix the blocker you can measure: Damage for an enemy wall, Health for survival, or Wins efficiency for repeated Evolution goals.
What is the best gamepass?
There is no universal best. x2 Wins targets repeated Evolution grinding, while OP Auto Clicker targets training convenience.
How are recommendations labelled?
The page distinguishes verified pass listings and core mechanics from player-dependent value judgments and withheld data.
