My solution was to generate random sentences in my head. I then iterate through the letters of each sentence, and if the letter is M or later in the alphabet, I select right. If the letter is before M in the alphabet I select left.

Try it alternating/ varying musical time signatures.

A decent strategy is to use the results of the last click to choose your next click. Win money, click right, lose money, click left.

Intrigued too. It worked very well for the first 100 iterations. Starting iterations 180, I entered a very deterministic loop (6 correct - 1 wrong - repeat), making me a money loser.

According to English letter frequencies [1] that gives a right probability of 3.0129+6.6544+7.1635+3.1671+0.1962+7.5809+5.7351+6.9509+3.6308+1.0074+1.2899+0.2902+1.7779+0.2722 = 48.7294 % even though you summed 14 of the 26 letters (a 13-13 split would lower the probability to 45.7165%).

I wonder if the patterns of letters in English language usage would still yield predictable patterns of left-and-right. Like naively 'the' is more common than 'zzz', so right-left-left may be more common than right-right-right.
