The idea of Xtract DNA is followed by the idea of a TouchRank, but with a special touch of primary nucleobases i.e. Adenine (A), Cytosine (C), Guanine (G), and Thymine (T). To begin the game, all you have to do is tap the red button repeatedly and quickly for 30 seconds. The number of touches appear on screen as number of DNA letters. Three DNA letters (e.g. ATG) make up words called codons. Once 36 letters (18 codons) appear on the screen, DNA strand is generated that appears in a little display cabinet. The aim for YOU, as a player, is to a big amount of letters to appear within 30 seconds. The nucleobases make up base pairing of strands to form, and that is how the sequence is generated that appears on the screen after the game ends.

It’s simple. Greater number of letters -> more DNA strands -> Longer DNA read/sequence.
