Card Shark Tutorial

In Card Shark you are tasked with remembering the details of multiple playing cards. The objective is to determine if the current playing card details match the card information that was presented to you a certain number of steps back.


Here is how Card Shark works:

Firstly, the number of cards that are presented to you will depend on the level of difficulty that you are training on.  In simple levels, there will be only two cards; while as you improve the number of cards will increase and that’s when the challenge starts.  For the sake of this tutorial, let’s assume that we are dealing with 4 cards.

  1. When you click START, you will see the details of a card (suit, value or both) as the card is being pulled from the deck. To explain this better, let’s assign a number to each of the 4 positions where the cards are placed, as you see below.

    When a new card is pulled from the deck, it will always go to position 1. And the card that was in position 1 will move to position 2. The card in position 2 will move to position 3 and the card in position 3 will move to position 4. They keep rotating as new cards are drawn. You will be ready to play when the very first card drawn moves to position 4.
  2. At this time, you should remember the value of the card in position 4 and respond  whether the cards in positions 1 & 4 match by using the ‘Yes’ or ‘No’ buttons. You will use either the left and right arrow keys on your keyboard or touching the buttons in case of touchscreens.

  3. Once you respond, the card in position 4 will turn to reveal its value.

More useful information:

  1. In this exercise, you have a limited time to respond.
  2. You can also try the step by step instructions by clicking the ‘i’ button at the bottom right corner of the exercise screen shown below.

    Note: When you try an exercise in a new level, the instruction mode is on by default. The way you can tell whether you are in instruction mode or exercise mode is to note the orange-color banner on top of the exercise screen which looks like the one below. You can always click on the ‘i’ to toggle between instruction mode and exercise mode.

  3. As you progress, the exercise will grow more challenging in the following ways:

    • You’ll need to decide if there is a match between the current playing card and a card presented further back in the sequence.
    • The actual information you’ll need to remember for each item will change (value, suit, both).
    • The card will be displayed for shorter periods of time.
    • The quantity of items you’ll be required to remember within the sequence will increase.
  4. Control buttons are found at the bottom right of the exercise screen. You can use these buttons to do the following:

    • If at any time you wish to repeat the Instructions on a particular exercise, push the’ i’ button.
    • If at any time you need to Exit an exercise, push the X button.
    • If at any time you wish to Pause the exercise, push the II button.
    • If you want to make the exercise Full screen for easier viewing, push Full screen button.
