Besides the familiar bets in sports betting, especially in soccer, like corner bets and other common bets, I've never tried pass bets.
General betting in soccer has been tried before, but pass betting has not been tried yet. However, after checking the Rollbit betting market, I couldn't find it.
Consider a match like Newcastle vs. Liverpool, which Liverpool won 2-3. Liverpool had 446 passes, while Newcastle had 248 total passes over the 90 minutes.
The total number of passes is still difficult to analyze. It's just a guess, and I don't know how many passes there will be during the 90 minutes.
If the odds are too low on a match, I think I'd prefer a normal 1x2 bet or BTTS.
These are common bets—most bets are on 1X2 and BTTS.
