Select cards from the deck at the bottom of your screen, use your fractals to purchase them (+1 fractal per turn). Place the card you selected anywhere on the board, press confirm and your cards will use their abilities in sequence. The enemy now gets to do the same. Keep fighting until either you or your opponent's health reaches 0.
A remix of Eureka, doubles the amount of cards in the game, with some references to older versions of the game. More features/cards may be added, and I will try to keep this updated to the current version of Eureka 3. Art is by me (With some art being taken from older versions), music is from wherever the music came from in the original game, I don't know where it is from.
