If you do so, you are only cheating yourself.

10.Is it possible to view your tactic rating history on lichess?

A: It's not possible to see your total rating history but, when you are on the puzzle page, you can see your rating history (last 12puzzles) on a graph on the left of your screen.

11.Are there wrong puzzle on Lichess?

A: Yes, some olds puzzles generated with limited calculation depth are wrong because:
-It couldn't account for all the possible wins.
-There are a better Solution to the puzzle.

12.How to know if a puzzle is it wrong?

A: If a puzzle you seems wrong, try it against stockfish 8.

13.How to report a wrong puzzle?

A: If you're sure that your puzzle is wrong create a new thread in: lichess.org/forum/lichess-feedback the session of the forums that covers Bug reports. Add your(s) game(s) against stockfish 8 for prove it. And if you're right, developers will disable it.

14.How do the developers for disable a wrong puzzle?

The trophy of 10.000 puzzles is gone! Why???
Solal35 commented :
10k puzzle trophy is no longer awarded. Lots of people misused the puzzles feature just to get the trophy, and since there isn't a 10k limit any more there's even less of a reason to keep it.
Ozymandias_Realista commented :
I make 10 k in this moment.
I make puzzles for 6 monks for this.
Is not fair i not win this trophy.
I play here for 2 years, just here, in this site, every day, i realy like here, and i win this
disappointment. Where i can complain?

I was training and it says that "You played all the puzzles! Sorry, we don't have any more puzzles for you. You played quite a lot of them, didn't you :)" when I know for sure that's not true and I know there's lots more for me to solve. What can I do so that I can keep solving puzzles and keep training?

Unfortunately I don't have the bugged puzzle number. I can't get to it anymore. I run Windows 10 and I have tried both Google Chrome and Mozilla Firefox. I am stuck. This is the error message I get:


Something went wrong on this page.

If the problem persists, please report it in the forum.

Or send us an email at contact@lichess.org

Answered by notDavid
Hi, sorry if this is a stupid question, new here and I've searched but couldn't find an answer;

In the puzzle history it says, for example after solving a puzzle:

"notDavid (1472) +14 Puzzle 28052 (1408) -77 200 s"

What's the meaning of the -77 ?
Solal35 commented :
This meaning the puzzle you have played lost 77 ratings points, because you have solved it. Is it more clear?
notDavid commented :
Ahhh okay that makes sense, thanks! :)
cd2017 commented :
I thought the max you could lose was 18 rating points (I failed a mating puzzle and it gave -18 points).
scorpionking303 commented :
i got -32 on a 2013 cause of my rating
lamdtc commented :
The puzzles themselves have rating points. That what this is referring to.

Can somebody please help me? I got to a particular puzzle and it clearly had a bug (I could not move any of the pieces). Now I cannot do puzzles anymore because presumably the system wants to move me to the puzzle with the bug and it won't even do that now. Thank you. eastyz
Solal35 commented :
Please share the bugged puzzle, your OS version and browser to help developers to fix the problem
