Welcome

My name is Colin and I'll be your guide to all kinds of gambling and probability-related maths in this blog. I'm happy to field questions and try to put right any errors you find. I ought to emphasise the DISCLAIMER:
The Martingale comes with absolutely no warranty of any description. You can use information contained herein any way you like (although if you republish it anywhere, you must include the disclaimer in full as well as a link to the original article), but it's not my fault if you lose all your money. Gambling may not be legal depending on how old you are and where you are. If you get busted, that's not my fault either.

You might well ask - why are you sitting here writing a blog instead of ripping Vegas to shreds, if you know so much about gambling? It's a fair question. My interest is more in sports betting than casino gaming, and I'm currently based in the US where such things are generally illegal - or at best, awfully shady. I'm also the kind of mathematician who's much more interested in solving complex probability puzzles than making much money using them. Which is why this is all free and accessible to everyone.

It's called The Martingale after a staking system that doesn't work, described in the following post. The url is martegal.blogspot.com because martingale was taken, and martegal is the Portuguese word from which Martingale was derived.
