Recently i made this kind of Simon Game using VueJS.

Simon is an electronic game of memory skill invented by Ralph H. Baer and Howard J. Morrison, working for toy design firm Marvin Glass and Associates,[1] with software programming by Lenny Cope. The device creates a series of tones and lights and requires a user to repeat the sequence.

In my implementation, the previous sequence is not memorized. Every time you hit the right sequence a completely new variation with a new step is proposed by the computer. This version is also "infinite", test your limits.

Here is the game link:
