please help me to know how to play tapa in brief
i keep getting this error "Solution is wrong. All 'Black cells' must be marked."
I suggest posting the image of a sample Tapa (25th and before) here on the forum so that someone can correct your solution and explain why.
In brief, the best I can do for now is direct you to these patterns - http://rohanrao.blogspot.in/2011/03/solving-tapa-elementary-beginni... to understand how the clue cells work. Other than that just make sure that all shaded cells are connected, and there's no 2x2 region entirely shaded. |

Location: United States | Minor note on the interface, when you press the Clear button, it says "Clear is undoable. Press 'Control' while clicking 'Clear' if you really want to clear the grid". Shouldn't that actually be "Clear is NOT undoable"? |

When will the Scoring Page displayed. Will it consider top 10% players in the first day alone or the three days, when a puzzle is available. Across 3 days. |

Location: United States | 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
thesubro commented at 2013-08-26 01:52:53
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).

"It's all gravy"
greenhorn commented at 2013-08-26 01:54:32
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 :|
rajeshk commented at 2013-08-26 09:33:22
Good puzzle to start with :)
kiwijam commented at 2013-08-26 15:40:42
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.

Nice easy Tapa with straight solving path.
sbeck commented at 2013-08-27 23:55:44
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
Nice puzzle :)
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.

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.

Location: The Netherlands | 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.
swaroop2011 commented at 2013-09-01 00:31:55
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.

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) |
