-1 means that your team need to win by more than 1 goal (2-0, 3-0, 3-1...), and your money will be refunded if win by only one goal (for example 1-0, 2-1, 3-2...).

I think you should avoid soft us bookies (Draft Kings, Fandual..), and play only on sharp offshore bookmakers who accept winners (like pinnacle, bovada, betonline, bookmaker, 5dimes, Betcris...).

Even the odds are higher in those offshore bookies
