The goal of the game is to be first to get rid of all the cards in the hand by placing them on a discard pile. The game starts by dealing six cards to each of the four players and placing one card face up in a discard pile. You must play a card of the same rank or suit over the card in the discard pile when your turn comes. In order to win you must have a very good strategy. What are you waiting for? Download and start having fun now! * * * FEATURES * * * - advanced AI players - intuitive interface - HD quality graphics - balanced rules * * * TIPS * * * - If you have an 8 or a joker you can place it over any card. - If you place a card of 2 the next player must take 2 cards from the stockpile. If he places a 2 the next player after him must take 4 cards and so on. - You can use the Jack to make the next player wait a turn. If the player before you places a Jack you can wait or place another Jack. - Following this turn the player who won't respond with a Jack waits a turn. - If you don't have a suitable card, you can draw one from the stockpile. - In order to wait a turn or take a card from the stockpile you need to tap the button next to your hand of cards. - If you don't have a suitable card after taking one from the stockpile, you must tap the "Jump" button. - You can use a 9 to reverse the order of the play. Normally the deal is done clockwise. - You can use an 8 to change the playing suit color. After you place an 8 a menu appears from which you can select the suit you want. - If other players specify a new suit using an 8, the type of the suit will appear briefly on top of the stockpile. - After a player plays all his cards, the round ends and points are awarded to this player. - The points are calculated by adding 10 points for each common card and 50 points for eights, Jacks, nines, and twos. - The first player to reach 300 points wins the game. - The game saves its state so you can exit the game and return from where you left. * Support and Feedback If you have any technical problems please email us directly at support@gsoftteam.com.

Wany to focus on learning all of the openings that start with a specific move, such as pawn to “e4”? This category can also be selected, and you can play against a computer that only plays lines that start with “e4”. The chess engine in this app is not Stockfish, and it does not look very far ahead. It is meant to provide a decent base evaluation and allow the majority of the reason behind the evaluation of the current position to be shown to the user. The following information can be shown to the user: • Positional advantages for each piece type (pawn, knight, bishop, rook, queen and king) • Piece value advantages for each color • Mobility scores for each piece where mobility plays a big role (bishop, rook, queen, king) • Pawn advantages and disadvantages (passed pawns, isolated pawns, backwards pawns, doubled pawns) • Total value of pieces attacked by each color as well as total value of pieces defended by each color A lot of chess games are won and lost within the opening moves, this app was designed to help players learn solid openings that either help them gain a winning advantage out of the opening, or at the very least help them not lose due to the opening moves played.
