Mutual betting

Why should I try mutual betting?
Mutual betting remains one of most adrenaline-pumping ways to bet for your favourite teams and prove yourself right. Why?

  • A bettor chooses a side to place his bet...and others place theirs.
  • Every bet made influences the winning multiplier until the pool closes.
  • After the match outcome, winners split the pot proportionally to their contribution
