Justice is a solitaire game played with any standard 78-card Tarot deck. The cards 1-20 of the Major Arcana (trump suit) are placed randomly in a 5x4 grid. Players draw from the deck of Minor Arcana cards, until depleted, using the cards to manipulate the grid and put the Major Arcana cards in order. By using a single Minor Arcana card or by taking the sum or difference of two cards, you can choose different cards from the grid to move, but you only ever have 1 type of movement available to you on a turn (Swap or Slide) and 1 direction (Left-Right or Up-Down). To change either the type of movement or the direction, you must discard your entire hand. The movement type or direction are also must be changed whenever the Justice is moved to a different place on the grid. To win, players must plan out their moves carefully so as not to waste cards. For an advanced version, at the 0 and 21 cards to the grid.
