In play is where a sportsbook is really tested. Odds have to move fast, bets have to accept, and the app has to stay up while everyone is watching the same match.
Tell us what you have found:
- which books stay responsive during a big match
- how often a bet gets rejected or requoted at the moment you place it
- whether cash out is offered, and whether it is available when you actually want it
- how far behind the live stream or broadcast the odds seem to run
If you have had a bet rejected repeatedly on one book and never on another, that is exactly the kind of thing this forum should be recording.
