Blinken brings a retro electronic memory game from the 1970's to KDE.
Table of Contents

Blinken is based on an electronic game released in 1978, which challenges players to remember sequences of increasing length. On the face of the device, there are 4 different color buttons, each one with their own distinctive sound. These buttons light up randomly, creating the sequence that the player must then recall. If the player is successful in remembering the sequence of lights in the correct order, they advance to the next stage, where an identical sequence with one extra step is presented. If they are incorrect, the game is lost, and the player must start again from the beginning. The goal is to get a high score - each step in the sequence is worth one point, so correct entry of a sequence of 8 lights is worth 8 points on the high score table.

Here is the screen that is presented on startup of Blinken, showing the general interface to the application. Most of the screen is taken up by the device, with the 4 colored buttons, with the device controls (score counter, button, etc.) in the center of the screen. The current status of the application is displayed on the piece of paper under the device. In the corners of the application, there are 3 buttons:

The Highscores button opens a dialog that displays the Highscores table for each of the 3 difficulty levels (the Highscores table can also be accessed by clicking on the score counter):

The Quit button closes the application:

The Help button is special, in that it reveals 4 sub-buttons. These buttons are shown when the Help button is hovered over, and provide access to the Blinken Handbook (this document), Show/Hide Settings, and the About Blinken and About KDE dialogs:

To become familiar with the workings of the game, you can interact with the colored buttons whilst on the main screen. The buttons will illuminate and produce a tone upon being pressed.
Once you are familiar with the workings of the application, a game can be started by pressing the button in the center of the screen. This “powers on” the device, as shown by the illuminated score counter. You can then choose the difficulty level that you want to attempt:

There are 3 levels in Blinken:
Level 1 is the easiest level, as it provides the longest time break between each sequence playback.
Level 2 is the intermediate level. It is identical to the previous level, but has a smaller time break between each sequence playback.
Level ? is the most difficult level of Blinken. It takes the timings from Level 2, but each sequence is totally random, rather than following on from the previous sequence, as in the standard game type.


Blinken is the ultimate memory game, though you need not possess the ultimate memory to be successful. These tips will help you in your pursuit of the best score:
If you have PC speakers, turn them on with the sound at a good level so that you can hear the tones alongside seeing the flashing lights.
Experiment with both the mouse and keyboard interaction methods, to see which one suites your memory best.
Try remembering the sequence as a list of colors.
Try remembering the sequence as positions on the screen.

To allow Blinken to be more easily enjoyed by certain users, there are several accessibility options built into Blinken.
To view and modify the accessibility options of Blinken, press the Ctrl key (whilst a game is not in progress):

To return to the game screen, press the Ctrl key again.
Alongside use of the mouse, Blinken also allows the user to operate the game using the keyboard.
The keys are 1, 2, 3, 4 by default.
To change the mapping of any button, click it using the mouse. It will then be highlighted, waiting for input. Press the desired key on the keyboard to change the currently assigned key.
There are other options available in the middle of the window: Sounds and Font.
By unchecking the Sounds checkbox, the Blinken sound effects will be suppressed.
By unchecking the Font checkbox, a standard font will be used for status text instead of the default handwriting font.
