Lightning is a card game on Aqua Venatus in which you try to get rid of all your cards before the computer does. When the game starts, you can drag one card at a time from your hand at the bottom of the screen to one of the four discard piles in the middle of the screen. If the arrow under the deck is pointing up, place a card that is one value higher on top. If the arrow is pointing down, place a card that is one value lower on top. Going up, once you get to 13 the next match is 1. Going down from 1, the next match is 13. There are 3 special kinds of cards in the game. Wild cards can be placed on any card and any card can be placed on top of them. Red cards with the circular arrow on them will reverse the direction of the deck. Lightning cards will score you a bonus if you place them on top of other lightning cards. If the computer gets stuck, the “flip it” card will appear. You can click it to put new cards on the four discard piles. Have fun!
