Hi,

I noticed that the undo button only goes back a limited number of steps.

As an alternative, would it be possible to allow the deletion of cells of a specific color (there are 3 of them to choose from). Often I change colors to explore a route, but without the undo, I am stuck deleting them one cell at a time - while I can drag to fill them in, it doesn't seem to work on the delete, so it is quite laborious!

Thanks, Raphael

Yes, the undo button works for only 7 steps.

Sure, it is possible. Also I think that you are so right about this, we should add this to make it easier for solvers to delete some cells

It's an hard start

Even harder when you mess up and dont realize it until 4 minutes into the battle. It akk gravy from here on out. (that is an American colloquialism ... which means it all has to be easier from this point on). TheSubro

Maybe I am doing something wrong, but everything I drawn appears in 2-3 seconds, not immediately. I have no problems at the other websites using online solving. Anyway, very nice puzzle at the beginning.

swaroop2011 commented at 2013-08-26 02:08:48
wow what a tough beginning and beginning with a mistake :(

---

prasanna16391 commented at 2013-08-26 09:10:31
I don't think it was tough. Big but not tough. For me this is the perfect blend to ensure that there's no need for guesswork and you're awarding enough logical thinking over just click speed. Stupid mistake from me though :|

Good puzzle to start with :)

good fun, thanks Serkan!

rvarun commented at 2013-08-26 23:48:51
Bigger and tougher one to start with. A nice puzzle. Personally I submitted without blackening one cell. But a much better one compared to last year where guesswork also have the possibility of correct solution.

Is there a way to see all players scores, instead of just the top?

As an unexperienced Tapa solver, I tend to not react to the connectedness condition of the wall. Guess I can halve my times once I get used to that :)

---

debmohanty commented at 2013-08-28 10:20:17
@carljohan, you still have impressive timings.

---

macherlakumar commented at 2013-08-28 12:25:23
Not a hard puzzle but paid the penalty(time to fix) for incorrect shading at the bottom.

Every time I review this one I like it more. Funny how that works. But as an author, I can appreciate the little limitations caused by the clues around the grid (a bunch of 1s are obviously gonna limit the middle)

---

rob commented at 2013-08-29 00:24:21
Great puzzle. Took me far too long to realize that a 33 neighbouring a 1 has consequences not just for the 33 but also for the 1. Then it was smooth.

---

rajeshk commented at 2013-08-29 16:28:44
Very good design. Took me some to time to get around 1s.

---

carljohan commented at 2013-08-29 20:29:08

tamz29 commented at 2013-08-31 22:20:49
Reminds me of minesweepers :) Top score :)

---

yureklis commented at 2013-08-31 22:28:50
Yes, you are right about minesweeper. This was my intention, actually it nicely worked.

---

Tapa player has been upgraded with 2 changes
1) Left click to unshade a cell now works consistently. (Ref : See Gareth's comment on 30-Aug)
2) There is no limit on number of Undos.

Thank you!

Ouch. brain freeze. Beautiful puzzle, but maybe a little bit hard for an online interface solve. I found some of it by quickly trying one way, something that'd be easier to "mark" on paper. Went back and solved it to confirm I got the logic of the harder parts.

---

swaroop2011 commented at 2013-08-30 04:02:30
awesome one :)

---

gareth commented at 2013-08-30 04:44:59
I wish that it was possible to unshade cells reliably. It just does not work properly in Chrome. Most of the time the click is ignored. You also can't drag to unselect. This bug was present last year too. It flickers, so it presumably is double-responding to the click event.

---

MellowMelon commented at 2013-08-30 07:07:23
gareth: try to get in the habit of right clicking to erase.

---

kiwijam commented at 2013-08-30 09:58:40
I had the same problem as Gareth, right-clicking doesn't help. Basically, if you don't spot the perfect path on this puzzle then you need to have a guess to move towards the solution. So I change colour and continue. But when the guess is wrong, I can only press Undo 8 times (new change since last year), but there's still cells containing my second colour that I don't want any more. How do I get rid of it? There's no eraser. No command to clear a cell. Just lots of clicking, not so fun.

---

carljohan commented at 2013-08-30 15:42:47
Agree with most of the above. Hard to erase, especially in Chrome. How about a way to erase all cells of one color? Isn't that the purpose of the colors in the first place?

---

ksun48 commented at 2013-08-31 01:03:50
I feel like that encourages bifurcation too much though.

---

There's something clearly wrong with reviewing solves today for me. I think that dragged cells get shaded and subsequently unshaded in the applet.

Absolutely beautiful. 10+.

After your comment I couldn't remember which Tapa is. So I solved again, frankly I like too. There are some nice things.

awesome puzzle. :) and the brilliant one :)

carljohan commented at 2013-09-01 10:55:31
Mainly based on one "trick" in the upper right, but the patterns that arise are quite nice.

---

I tried reviewing the recent tapa, but it didn't have a valid solution at the end, it had squares missing

Able to finish

Cute puzzle.

So, major shake-ups in top 10 after yesterday's Tapa. Really happy to see PS at 5th. Good job PS.

Thanks! Still kicking myself for getting a mistake on the first day. Funny that I was one of the most inconsistent last year and have started out really consistently this time (except that first day of course)

Can anyone please give me link to some more classical tapa puzzle pages as I can't find it on google too......also of last year CTC.

Nice intricate patterns even with the small size.

---

yureklis commented at 2013-09-03 00:50:48
Last night I changed this one. Previous one was very easy, I wasn't satisfied with it. I wanted to make a little bit disturbing Tapa in small size. I made this one, altough I spent much time than making a similar size Tapa, I couldn't do it what exactly I wanted. Because there is a crack of the structure in the left of the grid, 1/2s.

---

macherlakumar commented at 2013-09-03 15:08:39
Puzzle is good, after the competition I solved again (usually I do that for every puzzle) and I saw that left bottom1/2 and right top 1/3 are places where uniquness can be used to solve. The puzzle can be solved logically without using uniquness and I have solved this using some guess work.

---

muhorka commented at 2013-09-03 15:17:46
Nice puzzle, but in this one was better use uniquness that normal logic. But it still solvable without this fact.

---

carljohan commented at 2013-09-03 18:30:16
Couldn't solve this without guessing...

Here's last year's CTC link

You'll also be able to find Tapa among other puzzles on various blogs like mine/Serkan's/Palmer's etc. or on the Grandmaster Puzzles website.

prasanna16391 commented at 2013-09-04 00:09:32
A little difficult to start with. Perhaps I shouldn't have been so stubborn to not use uniqueness logic and actually see where the connectivity breaks. At least I didn't make a mistake on a big puzzle again like the first day.

---

macherlakumar commented at 2013-09-04 00:19:58
Honestly started at a point where I did not deduce any logic to shade it. Solved most of puzzle on guess work and intuition. Too hard puzzle for me, should solve it logically now.

---

prasanna16391 commented at 2013-09-04 00:25:16
Actually I looked back and tried to spot another break-in. Is R3C6 the only break-in? Quite a nice one, but makes it a little narrow. I'll probably have to go and see others' solves and how they've done it.

---

yureklis commented at 2013-09-04 00:43:22
Yes, it is difficult, but some of 35 Tapas must be difficult. This one is one of them. I planned to hide the starting point, I think it's done. You should consider these clues together: R2C5 + R3C7 + R4C6 (This is a clue pattern that I discovered recently). Then you can complete the puzzle smoothly.

---

macherlakumar commented at 2013-09-04 00:44:55
Just now solved it logically. R3C6 is the break-in (coincidentally this is where I started R4C7 just diagonal) where I found the solving path to progress quickly. After that it is all about connectivity. Brilliantly constructed with more difficulty level. 10+ :)

---

gareth commented at 2013-09-04 06:19:38
Too hard for me, but that's probably just me and not a criticism of the puzzle.
