@bubbled, I would interpret it this way: Round 1: Four games => 4 winners. Round 2: Two games => 2 winners. Round 3: One game => 1 winner. Seven games in all, and there are no "middle two" rounds. If that's right, my take is
@jasen, In an earlier post you said to switch boxes. (A) of course that is not permitted. (B) you can succeed even if the warden randomly re-positions them before each visit! @bubbled, if the statement is incorrect, that you say is incorrect, the puzzle has no 30% solution. We agree on that. So it's not a guessing game. It's a strategy-driven game. And the strategy does group the successes and failures to advantage for the prisoners. We're both traveling the high road, trust me. @bubbled, let's not discuss my last point right now. This is because to clarify what I was getting at would mean to restate it in "much too revealing" terms. Perhaps I'll do that as a later clue if needed. For now I'd rather not retract it "with explanation." Let me simply retract spoiler #3. That is, your objection to it is valid, but also your objection to it does not preclude a solution. And if I say more, I say too much. Thanks.
