One of the most popular tools among bettors today is the odds comparison services. They are specialised websites that continually analyse virtual betting shops’ lines in real time to help users find the best odds for their bets.

Apart from comparing odds, this kind of sites have a huge number of other functions – showing falling and rising odds, constantly updating sports statistics and other information that may be useful to the player.

There are many services of this kind on the Internet and the popularity of such resources will directly depend on how many betting sites they cover, what particular sports events are watched and what betting markets are monitored. Usually such services are completely free, but in some cases you need to register in order to use or get additional features.

Oddschecker, which was launched in 1999 and operates successfully nowadays, claims to be the oldest odds comparison service. The resource’s interface is in English.
