Short version, so you don't have to scroll: an offshore bookmaker is a betting site licensed somewhere other than your own country. Curaçao, Malta, the Isle of Man, that sort of place. Because the rules where they sit are lighter, they can run leaner and hand back a lot of that saving in the form of better odds and markets your local sportsbook simply won't touch.
That is the whole appeal, really. A domestic operator carries the cost of a heavy licence and passes it on to you as a wider margin. An offshore book, operating where the paperwork is cheaper, tends to price closer to the true line. Over a season, that gap is the difference between a hobby that bleeds money and one that roughly holds its own.
The markets are the other reason I keep an account or three abroad. Correct score, player props, obscure Tuesday-night leagues nobody at home lists. If it can be bet on, an offshore book usually books it.
None of this is a free lunch. Some of these operators are excellent; some are cowboys who will stall your withdrawal and hope you go away. The whole point of this site is telling the two apart.
