Bidding nil in Spades is a risky strategy but has the potential to turn a losing game into a winning game. When a pair bid nil, it means they expect or intend to lose all 13 tricks in the round. The likelihood of a pair losing all 13 tricks is minimal. When a pair bid nil and win nil, they are awarded 100 points. If a pair bid nil, they will win a ‘bag’ for each trick they do win in the round. When 10 bags are won over the whole game, the pair are deducted 100 points.
