Request: pyramid puzzles

Crew,

I'm keen to try the Pyramide puzzle that is today's rated puzzle on croco-puzzle.de, but am not sure that I have ever solved a puzzle like it before. A very quick search in the usual locations doesn't bring up other puzzles of the same type - or, if it does, then I just don't recognise them when I see them. Performing other searches comes up with all manner of other irrelevant results. Please could anybody point me to examples of the format for practice before I take today's puzzle on?

Is it as illustrated here, Chris? http://wiki.logic-masters.de/index.php? ... %C3%A4tsel If so, I'm fairly sure I've seen one not that long ago, but I'm danged if I can remember where.

There was one in the LMI evergreens 2 puzzle test (the september one I think) - although that had a funny rule about numbers on the bottom row being distinct...

I remember those, but I couldn't work out how to get started with them - which is why I was hoping for others to practice on before I tried today's rated puzzle. :-) (It shouldn't be that hard or that big, when some people can finish them in 20 seconds, but I still need practice!)

That's what I thought, until 8 mintes, and 2 mistakes later... It's only around 6 rows. 'Sum or difference pyramid' - I'm surprised you can't do 'past problems' on the croco site - that might help somewhat with the styles and rules.

Answering my own question, you can always go back through the Preisratsel archives, look for when the puzzle type was featured as a Preisratsel in the past and practice on those. They tend to be pretty easy, though - that said - I couldn't actually manage to crack the most recent Preisratsel Pyramide when I tried it. :-) I could solve the one before that, though, which gave me the encouragement to try today's rated puzzle.

Next question. When you're solving a rated puzzle, are solving using different colours and press "Testen", are you penalised with a Fehlversuche for an error? I solved today's puzzle colourfully in this way, pressed "Testen", had my error pointed out, corrected it, pressed "Testen" again, got the colourful flashy graphic and then got some slightly different text to usual. Then I checked the high-score table and no score appeared. I went back and completed it all in black with the answers I knew were correct, submitted that and had the overall time credited from start to (second) finish, without the Fehlversuche. Most strange.

Was it a weird one-off - some server-related quirk erring in my favour - or have I discovered a new technique? If I can try solving in colour, getting tests for "free" and then only converting to all-black before trying the test which might charge me with a Fehlversuche if it's incorrect then I have a brand new solution strategy.

I look forward to you replying with an answer to your own question! (again)
Although that's not really in the spirit of things, it might give u.vo something to think about!
[normally there is a 5 minute penalty for each false submission!]

Your problem must be some server issue. It does not make any difference if you solve the croco puzzles in a color different than black or in more than one color.

I can see 2 possible reasons for your problem:

- It is possible that you already lost the page without waiting for the response from the server.
- Or you had temporarily no connection when committing the results and the message you got told you exactly that.

In both cases starting the applet again has the effect that the applet forgets about the Fehlversuch, but because of the strange button-sequence at the start of the puzzle takes the starting time from the first try. If it's the second reason it sometimes helps to just wait a little bit and then press "testen" again. At least it worked for me once. The first one I encountered, too, when I was too frustrated with my result so that I clicked away the page as fast as possible so that I don't have to see my result only to then realize that this meant nothing was commited yet, but my time still running...

But before you think you found your way to highscore-heaven:
a) As mentioned before although forgetting Fehlversuche it is still the complete time of all your trials that is taken into account.
b) Fehlversuche are only punished by 5 minutes penalty for the daily highscore. For the rating table the penalty time depends on the average solving time.

So while it might make a bad time a little less worse there is no way to enter the top rating regions using this strategy. Apart from that: I highly doubt that any serious member of the puzzle community would use such methods. And if he does he certainly has other problems to think about :D.

Gang, would you be so kind as to test-solve these six, intended to be form part of a highly elementary introduction to Pyramid puzzles that I might post elsewhere today? I make no apologies for turning the difficulty wayyyy down low; the earliest ones are trivial or only barely above and the latest ones not much harder. I think these all have exactly one solution each, but another pair of eyes to confirm this would be welcome.

Code: Select all

PUZZLE ONE 

grey   ? ?
grey  8 2 4

PUZZLE TWO 

grey   ? ?
grey  2 4 6

PUZZLE THREE

white  ? ?
grey  2 4 6

PUZZLE FOUR

grey    9
grey   ? ?
grey  2 3 5

PUZZLE FIVE

white   ? ?
grey   ? ? ?
grey  1 2 4 9

PUZZLE SIX 

grey     7
grey    ? ?
grey   4 ? 5
grey  1 ? ? 2
If they aren't cooked then please do feel free to use them anywhere else where a really simple introduction to the style would help. We're all riffing off someone else's design at the end of the day...

They all LOOK unique to me, but my competence level isn't at its highest tonight. :D A third opinion would be welcome!

The first five seem to be unique, but my strategy on puzzle six is just to guess, I don't have the patience to follow the logic! (Hence why I got a Fehlversuch penalty yesterday, oops!)
