&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.

There are 3 levels in &blinken;:
</para>
<itemizedlist>
<listitem>
<para>
Level 1 is the easiest level, as it provides the longest time break between each sequence playback.
</para>
</listitem>
<listitem>
<para>
Level 2 is the intermediate level. It is identical to the previous level, but has a smaller time break between each sequence playback.
</para>
</listitem>
<listitem>
<para>
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.
