I got 50 hits in 100 tries. That being said, I did not particularly like hitting that poor frog :'( Yes, I am the kind of player who would never choose the rude option when talking to an NPC.

pure random player:

  (async function(punch, delay) {
    async function sleep(ms) {
      return new Promise((resolve, _) => {
        setTimeout(resolve, ms)
      })
    }
    
    for (let i = 0; i < 100; i++) {
      punch(['L', 'R'][(Math.random() * 2) | 0])
      await sleep(delay)
    }
  })(punch, 150)
  

"cheating" player:

  (async function(oracle, punch, delay) {
    async function sleep(ms) {
      return new Promise((resolve, _) => {
        setTimeout(resolve, ms)
      })
    }
    
    for (let i = 0; i < 100; i++) {
      punch((i + 1) < oracle.minForPrediction ? ['L', 'R'][(Math.random() * 2) | 0] : oracle.predictNextPunch() === 'L' ? 'R' : 'L')
      
      await sleep(delay)
    }
  })(oracle, punch, 150)

is it possible to do any better? i haven't fully read frog/oracle code

  oracle.predictNextPunch = function() {
    return myMove === 'L' ? 'R' : 'L'; 
  };
  
  realPunch(myMove);

  (async function(oracle, punch, delay) {
    async function sleep(ms) {
      return new Promise((resolve, _) => {
        setTimeout(resolve, ms)
      })
    }
    
    for (let i = 0; i < 100; i++) {
      const state = oracle._state
      const block = oracle.predictNextPunch()
      oracle._state = state
      
      punch(block === 'L' ? 'R' : 'L')
      
      await sleep(delay)
    }
  })(oracle, punch, 150)

I once coded a rock-paper-scissors game that you can play against a tree based matcher/learner, with symmetry between the options accounted for. Pretty similar idea-wise. To be honest, it was pretty hard to get a better than random score.

You should make one where you can play against the branch predictors of various processors.

I am briefly in the top ten after completely misunderstanding the rules nicee

Curious how a couple people got >100 hits on 100 punches

If you want to see what a random distribution looks like:

  jot -r 100 0 1 | rs -t 10

I noticed my "fake randomness" is lacking long sequences of the same key. I feel like I'm "predictable" when I press the same key 5 times in a row, yet that happens a lot in a truly random distribution.

Would be fairer if the frog occasionally got to throw a punch or two...

That was fun, got up to 79 :)

46 and that was my ceiling. frogs smarter than me.
