Questions about these tools
What is the difference between a team wheel and a team randomizer?
The wheel is the slow version: it draws every club on one dial, spins, and takes a moment to land — which is the point when a group is watching. The randomizer is the fast version, one tap for one club and nothing to wait for. Both draw from the same list with the same flat odds; only the ceremony differs.
Do the calculators use the official formulas?
Yes, exactly as published. Passer rating runs the league's own four-component formula and stops at its real ceiling, earned run average counts thirds of an inning properly rather than rounding them, and the handicap tool follows the World Handicap System. A calculator that quietly simplifies its formula is worse than none.
Where do the numbers behind these tools come from?
Public records — the seasons players actually posted, and the honours voted at the time. Nothing is projected and nothing is invented, which is what lets a calculator put your result next to real seasons instead of leaving it as a bare figure.
Why does each tool have its own website?
Because one page that does one thing loads faster and is easier to come back to than a suite you have to navigate. Each tool is a single purpose, a single screen, and nothing to dismiss before you can use it.
Do the daily guess games change every day?
Every day, on a fixed daily rollover, and everyone gets the same player on the same day so a result is worth comparing. Yesterday's answer does not come back around the next week.
Is anything here gated behind an account?
Nothing is. All 26 tools across these 6 sections open straight into the thing they do, keep whatever you type on your own device, and ask for nothing before or after you use them.
Do these work on a phone?
All of them. The wheels and randomizers are built for a thumb before a cursor, and every calculator field asks for a decimal keypad rather than dropping a desktop form onto a small screen.
