CTC Scoring system

The scoring system and formula are exactly same as last year.

  • 60 minutes allowed to solve the Tapa puzzle after you start
  • 2 minutes penalty for each wrong submission
  • 15% time penalty for each late day (maximum 2 late days are allowed – so a puzzle can be solved upto 72 hours after it is uploaded)
  • Each puzzle has its own points, which is computed from solving times of top 10% players on that day.
  • Each player gets points for solving a puzzle based on own solving time and others’ solving times. Exponential distribution is used.
  • Total points for a player is sum of puzzle points over 35days.

Like last year, we have provided 10 trial puzzles (16-Aug to 25 Aug).

There is no change in the solving interface, except that the number of steps you can undo back is limited.

    Interestingly, the Swiss top 3 were same as the Swiss bottom 3 in last year's CTC.

    When I use the review feature, sometimes a few cells are not blackened at the end of the review, which are supposed to be blackened. This isn't a big deal, but it's a small bug.

    I have only small feedback, but submit button should be better placed, for example next to a puzzle. For faster submitting puzzle...

    Yes, that is a bug, existing since last year. Didn't think it is important enough to fix.

    Agree with you. We needed the solving space to be as big as possible. So put all the buttons / colors / stars into left of the grid. The only thing I can say is "the submit button is equally far for everyone"

    About the Comments feature

    Please note that, as you might already have noticed, comments for a day's Tapa can be viewed only by players who have already solved the puzzle. So feel free to add any kind of comments about the puzzle, without worrying about revealing about the puzzle to other competitors.

    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.

    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"?

    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
