A quick note that I've been meaning to mention: I am colorblind and find the contrast between the two colors that are used in the stars for selecting your rating post-puzzle to be significantly harder to distinguish than the colors used to display your rating on the main yacht page. Would it be possible to use the same color scheme in both places?

I'm not used to using Penpa, and sometimes I wonder if there are shortcuts that I'm not aware of that would make it easier to use.
For example, if I make a mistake is it possible to 'Undo' the last move or two?
If I want to try something that I'm not sure about, is the best way to click the Clone button or are there any other options?
(or let me know if there is a Penpa info page or forum thread I should go to)

Undo is disabled in daily contests

Done - now using same color scheme in both places.

As mentioned, the Undo function is disabled for puzzles in Contest Mode. For trying out options, I don't like the Clone button so I either rely on my memory to know what to undo after a trial, or I switch to a different colour of line so that it's clear what's part of the trial and what is not.

Note that to change colors of shaded cells you want to enable Surface in the popup tool list, at which point you need to re enable line and composite to get them back.

This has been fixed. i.e. You don't need re-enabling. It was not correctly registering the tab dropdown earlier, but the update has been rolled out.

I will summarize here what others have already mentioned and some more.1) Undo has been intentionally disabled for online contests2) You can use "Clone" button to do your trials.3) Additionally, you can also use other colored lines for trials, Note: The solution check accepts all colors4) If you want to learn other shortcuts and other modes available, you can always refer to the readme document - https://github.com/swaroopg92/penpa-edit/blob/master/README.md [Also accessible through "I" button on top of the penpa_PLUS_ page -> Tool Instructions]I hope this helps.

We have to (temporarily) revert to the original color scheme. For reasons we still have not analyzed fully, the ratings are captured incorrectly because of this color change. We missed to test this while putting in the change. We have cleared all ratings received after this bug was introduced.

We have put in the changes to use same color scheme in both places.

Will there be any way to see solutions to any of these after the competition is over? I seem to have hit my wall with #13, 14, and maybe 15 and really really want to see the solution to Yajilin #13 at some point. Thanks in advance for considering this question.

Thanks everyone for participating in Yajilin Yacht! It's been a lot of fun these past few weeks watching replays and talking about these puzzles with solvers. It was great to see some new and unfamiliar names in the leaderboards. Congratulations to Walker Anderson for taking first place and becoming the first repeat daily contest winner, Freddie Hand for yet another commanding second place, and Thomas Luo for cracking the top 3! I hope that these puzzles were enjoyable and somewhat instructive for solvers of all skill levels.
If you're wondering how I intended these puzzles to be solved, I've prepared a playlist with a solution video for all 21 puzzles (5 trials, 16 contest puzzles) that can be found here: https://www.youtube.com/playlist?list=PL8RPcJPqpvOgGunGBxUxWoOZIyIpt...
There's even a few bonus puzzles in there too.
Additionally, I'll be posting these puzzles to my blog in the coming weeks with some additional designer comments - feel free to check those out if you're interested.
Until next time, thanks for participating everyone!
