Pick 5-card cribbage hands from a 6x6 grid. After the hand scores as a standard Crib Hand it will be removed from the board and the remaining cards and replacement cards will fall into place and the game continues.
However, if you fail to meet the target score on any hand the game will end. The more hands you score the higher the target score becomes.
The challenge is to choose hands that will score high but also leave yourself a good enough board to beat the threshold on the next hand.
