Overview System Requirements Reviews Related


Knave Defender is a space-invaders themed solitaire game where cards from a deck are assigned to one or more piles. The goal is to make the sum of the cards in a pile equal 21 (using Blackjack math) within a limited amount of time. Originally intended to be a blackjack trainer (focusing on the ability to quickly add up the cards in a hand), this casual game is always good for killing a few minutes.
