I know that Doven, Arrow keys move between the cards in my "Hand" and the caravan piles. However, no matter which card I select from my hand, using the arrow keys, and then pressing W to select it, when it comes to placing upon any of my caravans (The bottom 3) It shows as red, invalid, and won't let me place it. So I press R, cancel it and return that card to my hand, and try the next card in my hand, no luck there either, it shows as red invalid and won't let me play it. But I'm not understanding WHY it's red/invalid. I mean, I only have 1 card in each caravan, the next card placed will determine ascending or decending direction, however I can't seem to play any of the cards in my hand, on any of my caravans, and I don't know why they are invalid cards, or what would be valid cards in this situation.
hmm.. interesting.
now that you have clarified your issue.. lets give this a shot.
first off .. three "starter" cards HAVE to be played before the piles (caravans) can be build upon. Looks as if you got that down. First card in pile defines suit. cool.
Your next card determines acsending/decending value for the rest of play (or until a queen is played).. So. lets look at just one pile.
which you can place using those same arrow keys Say you play a 10. as an opener for the pile. You have to play something below the 10.. 9,8,7.. so on. Next card under that has to be lower again. so example. 10-7-5 = 22. you could not play 10-7-7 or 10-7-8.. as you cannot break acsenion.. UNLESS you play a queen on the last card of that pile.. example.. 10-7-5-Q-anything over 5.
Jacks allow you to take out any card in the game.. either player. 10-7-5.. play Jack on the 7. Now you only have 10-5
Kings DOUBLE the value of the card.. either player.. so can be used to "bust" the NPC's pile. Example: PC has a pile thats.. 10-9-7 = 26. you can play a king on the 10.. 10+k-9-7 and now the PC is at 36 BUST.. Pc then has to break that caravan and start over. (that pile)
Jokers.. allow you to take out ANY card.. (including your own so be carefull) from the current turn.. example: P1. 10-7-5 P2. 10-6-4 P3.. A-3-5 Playing a Joker on the first 10 in 10-7-5.. will KEEP that ten.. but all other tens on the board ... are discarded. so it would look like this.. P1 10+joker-7-5.. P2. 6-4 P3. A-3-5.
now.. you should be able to play any card Under or over whatever First card starts your pile.. But you cannot duplicate. ie. 10-10.. or Ace-Ace. ect.
maybe this will help a little.. not sure
cheers
