What Walt covers
Walt Ferrante is the pen name of the craps.us writer who owns the numbers. Every house edge, payout and probability on the site passes through his hands before it is published, and every one of them is produced by the same calculation module rather than typed from memory or copied from another table. When a figure changes, it changes everywhere at once.
He writes the guides to individual bets, from the Pass Line and the odds bet to the proposition box, and the strategy pages that test systems like Iron Cross, the 3-Point Molly and the Martingale. The goal on each page is the same: show what a bet pays, what it costs over time and why.
How Walt works
Walt starts from the 36 outcomes of two dice and builds each result up from there, so a reader can follow the working without trusting a source they cannot see. The formulas and the test results are published on the open math page, and the calculator and simulator on the site run exactly the same code.
Simulations are seeded, which means anyone can repeat a run and get the same answer. When a page quotes a simulated result, it says how many shooters or sessions were dealt and rounds the figure sensibly. Exact house edges never come from a simulation; they come from the arithmetic, and the tests check that the two agree.
He is blunt about what math cannot do. No betting pattern changes the house edge of the bets inside it, and he will say so on a page about a system that promises otherwise. What math can do is show which bets cost the least, and that is where most of his writing ends up pointing readers.
Where Walt's work starts
Readers new to the numbers can begin with the craps odds page, which lists every dice total with its probability and every bet with its price, then move through the bet guides. The Pass Line guide shows the 1.41% edge, and the odds bet guide explains why backing a line bet adds no edge of its own.
Walt also looks after the tools that run on the same module: the odds calculator, the payout trainer, the Strategy Lab simulator and the roll log. Each one returns the same answer as the guides because they share one calculation, and none of them asks for money or an account before it will work.
His strategy pages put named systems against the arithmetic: the Iron Cross, the 3-Point Molly, the 5-count, the Martingale and the Don't Pass approach. The verdict on each is measured rather than asserted. The Iron Cross, for example, wins on 30 of the 36 possible rolls and still loses money over any long run.
Why a pen name
The writers at craps.us publish under pen names. The work is judged by whether the numbers are right, and every number can be checked on the site itself, so the byline is a way to know who is responsible for a page rather than a claim to a résumé. Corrections go to the contact address and are dated.
If you find a figure that disagrees with another source, the open math page shows how ours was produced, and the contact page is the quickest way to raise it. A disagreement usually comes down to a rule difference, such as how a casino charges commission on a buy bet, and the pages note those variations where they matter.
