Value Slider

This game is used for Weeks 19, 22, and 23 in The Memory Drawing Course Book. It helps you make the most of every glance.

The goal of this game is to remember a target value that will be shown to you next to a control value. The control is present in order to give the target value some context. The white of the lesson’s background can also give you context. Note that you might need to resize your browser’s window in order to see the entire game on the screen at once.

Match the Value Game Directions

Notice the four buttons in the game below. The first two are simple timers. When you select either of them, three things happen:

  1. The value of the control square will change to a random value.
  2. A randomly valued target square will appear.
  3. A timer will begin counting down the number of seconds indicated by the selected button.

Your task is then to memorize the value of the target square during that viewing period.

After the timer’s duration ends the target square will disappear and a range slider will appear. At that point you would use the slider to attempt to match the memorized target value.

When you think your attempt is correct, click Check. The game will then show you a section of the target above your attempt and give you a percentage indication of how close your guess was.

The remaining two buttons are similar to the first two except that they include a wait period duration after the viewing period. During the wait period:

  • The target square disappears.
  • The wait period timer begins counting down.

After the wait period timer finishes, a range slider appears and you can make your attempt.
