Reason #1 I like Bovada:

Play for free
with no hassles

Most online casinos insult you with popups and spam, and they give you the hard sell even if you just want to try their free-play games.  Fortunately there's Bovada, which is the opposite.  That's the primary reason they're the only online casino I accept advertising from.

  • No registration required.  Most casinos let you play for free with fake money, but there's a catch: They make you register an account first.   That's not just a hassle: after you register you can expect them to badger you by email trying to get you to deposit real money.  But Bovada lets you play right away without forcing you to register an account.  Just close any registration boxes that appear, and then you can play without registering.  Here, try it.
  • Plays right in your browser.  If you'd rather not download the casino software to your hard disk, you don't have to.  The games play right in your web browser.  Nice.
  • Works on Macs.  The play-in-browser games are MacOS compatible!  Before Bovada, Mac users were pretty much out of luck for gambling online, even for free-play.  Not any more.

Bovada's not perfect, but there's no better site serving most of the U.S.

How to test your betting system

Practice craps with fake money or real money at Bovada

Betting systems can't overcome the house edge.  I present four different kinds of evidence as to why that's true in my article about betting systems.  Centuries of investigation, professional mathematicians, and countless computer simulations all say the same thing: betting systems simply don't work.  But if you're undaunted and really want to test your system, read on.

The wrong way to test your system is to gather random roulette spins, baccarat rounds, or craps rolls and then apply your system to it.  The reason this fails is that it's impossible for you to hand-check several thousand rounds.  After a mere thousand rounds your system might show a profit out of dumb luck, while with most other sets of data (or real-world experience) it would fail miserably.  So, forget the idea of hand-checking round results against your system.

The only way to do test a system properly is to run a computer simulation (either one long session of millions of rounds, or thousands of short sessions).  Running a computer simulation means either hiring someone to write the program (probably $100 would do it), or learning how to program it yourself (would probably take about a week).  To hire someone, try Fiverr or Upwork.  To learn programming, try Udemy, Code Academy, or Learn Python.

How the numbers are generated

I wrote a program in Javascript, using the built-in Math.random() function.  In most web browsers (Chrome, Safari, Firefox) Javascript uses an algorithm called Xorshift128+ to generate pseudo-random numbers.  This is way more than adequate for testing betting systems.

Some people hear that computers don't generate “real” random numbers, they generate “pseudo-random numbers” (true), and therefore conclude that computers are inadequate for testing betting systems, and that their systems can beat the real world of a casino even if they can't beat the numbers generated by a computer (completely dead wrong).  For all intents and purposes, the numbers generated by Xorshift128+ or any of the other modern algorithms are virtually indistinguishable from real random numbers.  They pass batteries of statistical tests for randomness, including frequency distribution, gaps, repetition, and predictability.  The bottom line is, you can't tell the computer-generated output from the real thing, and the statistical quality is virtually the same.

Practice gambling with play money

Before you throw down your hard-earned cash in a casino, PRACTICE FIRST!  Learn the games with play money where it doesn't cost you anything if you lose.  Seriously.

I like Bovada's practice games the best, because you can play right away without registering for an account.  Most every other online casino makes you give up your email address just to play the fake-money games — ugh.  That's why Bovada is the only online casino that gets space on my site.  I hope other casinos will eventually start treating their visitors like human beings rather than walking wallets, but until they do, there's Bovada.  One click and you're in.
