Crossword SNITCH

A quantitative guide to the degree of difficulty of the Times Cryptic Crossword

Solver Types and a Neutrino Detector

The SNITCH has always relied on a set of Reference solvers to calculate the difficulty of the crossword. Updating this list over time has led me to look at different types of solver. In particular, it has been important to detect and remove "Neutrinos" from the data (see further below). Once this is done we can look at other types of solver more clearly.

What's a Neutrino?

Neutrino – A person who manually solves the puzzle on paper, and then goes to the Crossword Club and types in the answers as rapidly as possible, either in order to give a high position on the leaderboard or because they are entering a typing competition. (Times for the Times glossary definition)

Have you noticed that the top of the Times Cryptic Crossword Club leaderboard is occupied by solvers who have some remarkable completion times? How does someone solve the puzzle in around 2 minutes, when it probably takes that long to just write in the answers?

On the Times for the Times blog site, we've come to know these solvers as "Neutrinos", a term coined by Tony Sever some years back to describe those people who like to occupy the top spots on the leaderboard without actually being top-notch solvers. The theory is that these people do the crossword on paper, then transcribe the answers on the Crossword Club interface.

And the big question is: how can we detect these? Some of them are pretty obvious: if you look at the results at the table on the right, the top solver in recent months is devlin with an average solving time of 00:43 (min:sec). Given that this is faster than average times of the known best solvers, we're sure that this is not a real solving time. But it's much harder to tell when you're talking about average times that are in the realms of possibility. Who are the Neutrinos and who are the real solvers? This page tries to answer that question.

Clusters of solvers

The chart below shows a way to separate Neutrinos from other solvers. It plots each solver's average solving time (in seconds) on the x-axis against an "alignment to SNITCH" factor on the y-axis. This alignment factor is 1 when, on average, a solver's personal NITCH rating for a crossword is proportional to the SNITCH rating for that crossword. It is 0 when there is no alignment. (For those interested, more detail on this is provided below).

The blue dots on this chart represent the Reference solvers for the SNITCH as of Oct 2018. (Note that you can hover over each point to see the name of the individual solver.) As you'd expect, these are clustered around an alignment factor of 1 (generally between 0.5 and 1.5) regardless of their average solving time.

The red dots represent solvers who have been around for some time but are not Reference solvers. A group of these is spread across the range of average solving times and also spread about the SNITCH alignment factor of 1. But there's a cluster of red dots in the lower left corner that has low solving times and is spread around an alignment factor of 0. These are the classic-style Neutrinos - those who are very fast on average, regardless of how hard the puzzles are.

This data suggests that any solver with a solving time of less than, say, 8.0 minutes and a SNITCH alignment factor of, say, less than 0.5 could be safely classified as a Neutrino.

The grey dots represent new solvers since the Reference solver list was baselined in Oct 2018>. We can now see that some of these are clearly Neutrinos (the ones in the cluster at the lower left, for example). Others with low solving times need further investigation, and we do this by checking the details of their alignment with the SNITCH.

Remaining Questions

We see that some solvers have alignment to the SNITCH figures well above 1, which would suggest that they seems to find harder puzzles especially hard. These solvers often have small data sets, including those with relatively high average solving times that don't always make the top 100 on the leaderboard. With the smaller amount of data, the alignment is likely to be less reflective of their true performance.

Blog Solvers: adding solving times from the blog

On the Times for the Times blog site, solvers regularly report their solving times. Where they have allowed it, we now add them to the list of solvers and track their progress. This is a new category of solver, the Blog Solver, for those who've reported solving times regularly over the last six months.

Notes to Blog Solvers:

  • the most reliable format for reporting times is with format "mm:ss" or as "x minutes" in the title or at the start of the entry
  • only the first main comment for each blogger is used; responses to other comments or a second comment is ignored.
  • to report errors, include "n errors" just after the time
  • If you just have a time it is assumed you have no errors unless you mention DNF or pink squares or giving up, etc, in the text
  • Examples of good time notifications are "38:30, 0 errors" and "39 minutes, 0 errors" in the comment title or as the first part of your comment
  • This info is also available using the "Blog Solver" button on the right hand side of the detailed crossword solving times for each crossword

Updating solver status

This analysis allows me to reclassify solvers, as shown in the chart below. One of my main motivations is to be able to update the list of Reference solvers reliably. I'd like to be able to include new solvers (especially good ones) without accidentally including Neutrinos. And I'd like to track other non-Reference and non-Neutrino solvers, even if their data isn't used for the SNITCH.

So I can now classify solvers as follows:

Neutrino
Those with fast solving times and low or inconsistent alignment to the SNITCH (shown in orange)
Reference Solvers
Those aligned to the SNITCH and having an average solving time of less than 45 mins (shown in blue)
Tracked Solvers
Those that don't meet the conditions for Reference Solvers but I can be fairly sure are not Neutrinos (shown in red)
Blog Solvers
Those that report their solving times in the Times for the Times site (shown in purple)

New solvers will come into the list over time and can be reclassified on my next update.

I've shown the old and new status in the full table to the right so that you can track the changes for each user.

So what's the SNITCH alignment factor?

This is actually pretty straightforward if you know a little maths. I plot the solver's individual NITCH scores agains the corresponding SNITCH for the same puzzle and measure the slope of the line of best fit. A slope of 1 indicates that the results are proportional, a slope of 0 means that there's no correlation.

For example, verlaine has results as shown in the chart below. Easier puzzles (according to the SNITCH) are on the left of the x-axis, harder ones on the right. verlaine's NITCH results vary, but are generally higher as we progress from left to right. The overall slope of the line of best fit is 1.19, showing good alignment with the SNITCH on average.

In contrast, PaulCooke has results as shown in the chart below. There is no correlation with the hardness of the puzzle according to the SNITCH. In fact, the slope is negative, meaning that on average the harder puzzles are easier for PaulCooke than the easier ones. This lack of correlation is exactly what you'd expect if the solver is just typing in known answers.

Nothing is simple and we have some solvers with a mix of results like the ones shown in the chart below. The correlation with the SNITCH is inconsistent - good on some solutions but not on others. On the latter, the solver looks just like a Neutrino, with short response times regardless of the SNITCH value. Presumably they type the answers in directly on these shorter puzzles. For this reason, where we detect this sort of solver, we will mark it manually as a Neutrino.

Solving times for club members

The table below shows crossword club solvers who have submitted more than 20 solutions in the last six months, with an average solving time of less than 60 minutes for an error-free crossword. They are ranked by that solving time. It also indicates their status, including whether they are Reference solvers for calculation of the daily SNITCH.
