All games must start on the scheduled date for bets to have action. For settlement purposes extra innings do not count. If a game has been postponed or cancelled before its due start time then all bets are deemed no action.
With the new 1Up, 2Up and 3Up Markets, you don’t have to wait for full-time anymore. If your team goes ahead during the match, you could already be celebrating a win – even if the game isn’t over.
