GAME OVERVIEW Game Concept The game is the classical card game solitaire. The game is played with a single pack of 52 playing cards. After thoroughly shuffling the deck, 28 cards are dealt face down to form the tableau which consists of 7 columns of 1,2,3,4,5,6 and 7 overlapping cards from left to right respectively. The exposed card at the end of each tableau column is turned face up. The goal is to get all the cards sorted into the suit slots where the cards have to be arranged in ascending order starting from ace.

Genre Card Game

Target Platform Android and PC

Target Audience casual gamers and Card game lovers of ages 12+

Game Flow Summary The game is re-playable as each time the game starts the cards are reshuffled and rearranged in the format described above with the same objective. The player competes against himself to get the fastest time and improve his win percentage.

Development Software Unity 3D 4

GAMEPLAY Game Progression The game is a where cards are shuffled and then placed to form the tableau which consists of 7 columns of 1,2,3,4,5,6 and 7 overlapping cards from left to right respectively. The card at the front of each column will be turned face up and the rest will be turned face down. The rest of the cards are placed in the draw pile where the player can click and can cycle through all the cards that are part of the draw pile. When a card is removed from the dray pile the card before it is in view again

Objectives The goal is to get all the cards sorted into the suite slots where the cards have to be arranged in ascending order starting from ace. Each suite has its own slot it has to go into.

Game Structure Cards can be attached to one another in such a way that a red card can only sit on a black card of the number of just one higher than itself i.e. a 6 of hearts can only be placed on either a 7 of spades, a seven of clubs or on the 5 of spades that is already in the spade suite slot. Cards that are initially face down in the play area can only be turned over if the card in front of them is removed and put in a suitable place.

Play Flow The game is highly replay able as the beyond 10 ^ 60 so the chance of the same game playing out in front of the player is beyond miniscule. The player gets satisfaction from beating his own high score and improving his win percentage 5

Game Mechanics Card Generation The cards are created using a prefab and a nested for loop at the start of the game. The inner for loop changes the value of the cars i.e. 2,3,4… and the outer for loop changes the suite i.e. spades, clubs…… the cards are assigned into an array where all the cards are stored initially. Then using a for loop random elements within the array are swapped with each other such that the position of the cards are changed and the deck is shuffled this swapping is done 500 times to keep the game different each time.

Card Distribution The cards are then distributed in the way described in the Structure using a nested for loop where the inner one decides how many cards to put in the column and the outer one changes between the columns.

Card Slot The card slot contains all the cards that are not in the play area at the start of the game and when we click on the card slot it cycles through all the cards in a linear order if a card is removed we can see the card below it cards can be moved from the card slot to the play area or suite slot if a suitable position is open for them else if they are dragged out and not placed in a suitable position the card resets back into the card slot.

Card Script The Card script contains the logic to detect whether a card has to be flipped or not. When a face up card is click on its collider is disabled and its position is set to the mouse or touches position and when the finger or mouse is released, it also checks the logic for detecting if the card has been placed in a legal place if it is not the cards position is reset. To its original position in both cases the collider is re-enabled. This is the most important script in the game and is shown below
