Five calculators for the arithmetic every bettor should be able to do: what a price implies, what the fair line is with the vig removed, what a market charges, and how to size a stake. The same helpers run inside the Blitzen terminal — no signup, no picks, no promises. Just the math.
Everything here is mechanical price math — de-vigging, unit conversion, expectation, and sizing. None of it predicts a game, and none of it turns a bad number into a good bet: EV and Kelly are only as honest as the probability you feed them. That part is on you (or your model).
The terminal runs this same math across every book on the board — and grades every model against the closing line, in public.
