How our tools work
Built on published numbers
Calculators use the rates and counts the developers or trusted guides have published, linked next to each number. You can also type any chance you believe in, and the tool does the math.
The math is shown
Each calculator prints its formula, so you can check the result yourself. A chance of 1 in 100 does not mean you get a hit by roll 100: the calculator tells you how many rolls give you a 50% or 90% chance of at least one.
Private by design
Tools run in your browser. Checklists and tier lists are saved on your device and never sent to us; see the Privacy Policy.
Frequently asked questions
What does the tools page list?
Every tools page on GamePowerUps that is live, with the date each one was last checked. A page appears here only after it has been checked against its sources.
How are these pages checked?
Each page names the sources it rests on and the date we last checked them. Codes count as active only when two sources updated in the last 7 days agree, and rumors are never stated as facts.
Is GamePowerUps official?
No. GamePowerUps is an independent site, not affiliated with or endorsed by any game developer, publisher or platform.
