Calls
This is a unique mode in which you can win your opponent's cards. But be careful, if you are wrong, then your cards will go to the opponent.
This mode is suitable if you are completely confident in the outcome of the event. Your opponent bets on a different outcome and the one who turns out to be right takes all the cards.
In cases where a sporting event can have three outcomes (Victory for team AAA - a draw - a victory for team BBB) and both users were wrong, then they remain with their cards.
