Enigma

Enigma is a 1-player game of logic for multiple systems.

The player starts with a deck of cards and, as they draw cards, must accept or reject each card. The game has an underlying rule to which cards should be accepted or rejected, and the player must determine this by closely watching which guesses are accepted or rejected correctly. The goal is to score 100% on a 52 card deck to complete the puzzle, and there are five rules in total. The player can start with 52 random cards, or an accurate deck.
