ECK: A Solo Trick-Taking Card Game

ECK (like "Deck" without the "d") is an abstract single trick-taking card game in which you play against the AI ​​opponent ECK and try to collect trick cards by winning exactly the number of tricks indicated on the available trick cards.

The ranks of the cards are polygon shapes, with increased complexity meaning increased trick value: line, triangle, square, pentagon, hexagon, octagon. The colors are red, orange, yellow, green, blue and purple.

There are 6 ranks (shapes) and 6 suits (suits). There are also 6 circle cards: three white and three black, which act as trump cards. The small circle symbol under the shape in the upper left corner of a suit card is a suit symbol, designed to help those who may have trouble distinguishing suits.
