EventHorizon, I'm not grasping the method. In particular, I can't tell if the "group of three (or more)" is always at least three, or if it resets upon color change. In particular, how would you point the backs for the opening sequence, and what would suits would the observer call?

was reviewing some older threads for inspiration or possible extension puzzles when a comment EventHorizon made got me thinking anew on this one.

Spoiler for It's nice to be correct, but mistakes allow learning...

a little more specifically - can we gain extra bits of info from a revealed card that is different then expected. have a solution for 36 and would not be surprised if that could be bested by one or two. pretty interesting approach and totally different from the two 35 card solutions if anyone is interested.

Is it possible to examine the back of every card before they begin turning them over?

hey hey phaze - very glad for the question and interest. to answer though, no. the only info the guessing logician has to go by are all previously displayed cards and the direction of the plane on those cards as well as the direction of the plane on the top of the remaining face down deck.

Spoiler for a slight modification on my previous HINT

well, when i said

i wasnt totally accurate. in my 36 card solution, i did use a principle used in the 35 card solutions; at least initially. after that the prior solutions methodologies are indeed different.

Had bumped this thread over a month ago after an extended period with a previous optimal answer. It's about to go off of the front page of the forum and even though there is at least one person following this topic (that you plasmid?), think it's about time to offer another solution. Besides, suspect this solution can be bested.

Spoiler for a solution with 36 correct suits predicted

Think that logic is sound. 37 anyone?
