Read full description

MugenCards is a simple card game that can be played endlessly. The player is presented with two to six cards. Pick a red card and your coins will increase. Pick a blue card and your coins will decrease. You can pick a card simply by pressing one of the cards shown on the screen. After picking a card, you will then proceed to the next round. Try to keep playing for as long as you can by avoiding the blue cards! If your coins reaches zero, then it's game over. As long as you still have some coins left after picking a card, you will be able to proceed to the next round. The speed at which the blue card switches with a red card will increase as you proceed to higher rounds. The coins you can earn/lose from the cards will increase with each round, thus both the risk and reward of playing another round will increase with each round you decide to play. Try to pick a red card each round!
