drkSimon is a memory game for smartphones. It uses the principle of the famous 80’s arcade game simon.

This game is developed and maintained by Philippe Bousquet <darken33@free.fr> since October 2013 and is distributed under the terms of the GNU General Public License v3.

The graphics were designed by Philippe Bousquet and distributed under license Creative Commons BY-SA.

The sound effects have been made through free software, such as Jackd, Qsynth et Audacity, and are also distributed under license Creative Commons BY-SA.

Here a video of my first tests:


To bring up the menu simply press the <menu> button, then you can define the level of play in the settings.

To start a game, press the <Simon>, you must repeat the color sequence proposed by the game.As long as you do not make an error, a color is added to the sequence.

How long will you take before you make a mistake ?

Good luck.
