I tried to study the behaviour in relation to the lights and then predict the most likely outcome from a combination or single light
I STUDY THE TABLE AND USE MY INTUITION
I tried to notice if there were patterns when more than one light was on. It was easier to look for patterns this way in the end than single lights. Sometimes I just had to guess as there's no way of knowing based on all different light combinations.
I tryed to guess the patern by observeing the times that the sound occured and concluded that it was the number of lights on that was important to the outcome.
Just visually looked at the colours that were making a noise and made a decision
Per each sound, I tried to note the number of lights on over the number of that colour overall, i.e 12/17 - 12 red lights on out of 17 red lights on when the sound played. I did this for each colour. I also tried to spot patterns in lights when the sounds were on - i.e. '0 3s' meant there was no sound when all 3 colours were lit. There were often no patterns for multiple colours though.
I tried to identify a pattern around number and colour combination
tried to note down every type of light sequence that triggered a ding or no ding and then if there were some that were both ways took a random guess when i was asked - but quite often there were specific sequences that were just ding or no ding so felt these had a good chance at being the right answer.
i noted down what pattern was more frequent
In the beginning I tried to identify individual colours and how often a ding was made. After round 2 I tried a more 'global' approach to identifying any possible patterns rather than individual colours. The latter seemed to give me a little more confidence in my choices, but strangely less confidence in the hit rate overall. While deciding my choices, I mostly ignored what state the 'other light' was in, as I couldn't possibly get that right with any degree of confidence. I felt it was best to go with the evidence/patterns I saw in front of me, and continue with that based on chance/percentage of getting it right as shown on the graph.
I would try to come up with high level rules in logical terms
I made notes on the lights shown and their affect on the sound. I didn't consider the other lights not shown really.
I tried to look for patterns of which lights fitted with when sounds were on and noted down frequency. I tried to identify what lights were generally on or off when the sound was made. I then based my prediction on what was most likely for when that colour was on.  I did find it quite hard trying to read across all 27 rows with so much information on screen - a smaller block would be easier to follow across with the eye
I didn't really have a strategy. I tried to remember the most common one where the sound was made.
I tried to make notes as concise as possible to make as many as i could for each combination. I then looked for patterns and tried to get those patterns confirmed by 2 if possible as occasionally, 2 patterns had different outcomes, at which point it was a 50/50 guess
i tried to only record when the light was going to be on. some of them were contradictory so i just said it wouldn't ding if i didn't know
I looked at what was going off with the ding and tried to write which ones were and weren't going off.
I think I just did the obvious and tried to find which light corresponded with the sound the most. Then just a case of slightly randomising prediction to try and cover any deviations from these so-called rules I formed.
I tried to note down my strategy in my description box and study the changes
I examined the machine data for repeating patterns. More often than not, there were instances of vague correlation which I think made notes on. For the most part, there weren't iron-clad patterns but one or two examples in each set of data was enough to convince me to pick this out in my predictions.
I just studied the coloured lights and the dings. I looked at individual colours and if the lights went on together with the dings. I also did look at if there was any correlation with odd and even numbers.
Looked for patterns. Was not easy.
I observed the frequency with which a combination of lights occurred with a ding, and if this combination occurred without sound - indicating that an unobservable light affected the outcome.
I tried to make predictions based on my notes
tried to see how many lighs needed and then guess of the ? was on or off
i would just follow my notes and if the machine had lit up like that, i would have predicted it to light up if it had only light up sometimes i.e on a green light, i would choose yes for one option and no for the other
I looked at what caused a ding and noted it
First, I estimated the frequency of each color and then tried to notice any patterns in the lights if the frequencies where lower than 60%. I looked at how many colors where lit in relation to the sound occurring to see if any patterns where based on the number of lights active
made ones of ding combinations
