Date: 10 Aug 1981 0841-PDT From: Tom Davis Subject: Barrel Puzzle instructions To: cube-lovers at MIT-MC I just purchased one of the "Wonderful Barrel" puzzles mentioned in Stan Isaac's note, and I found the enclosed set of instructions to be a classic. I figured I'd pass them on, in case some of the members of this list don't buy the puzzle itself. The first couple of paragraphs are not so great, but it gets better toward the end. @begin(verbatim) "Wonderful Barrel" is a kind of mental game plate also can be regarded as an indoor ornament. The red, orange, yellow, green, blue, black color balls which is inner in barrel can create more than 10 billion combination to reach a solution and finally be aligned on 5 straight lines, yet each straight line are with 4 same color balls. * PLAY RULE * Original alignment circumstances is as follow: there are three black balls are set on SHELTER but each black ball is above a shore of PLUNGER; the 5 straight lines are up the SHELTER with different color from one another, each line contains 4 same color balls. The 5 straight lines are aligned in clock-wise with blue, green, yellow, orange, red color. As you know, the original alignment is orderly, now you can circumvolve DRUM, then operate plunger up and down for taking the ball out from SHELTER. While you put the ball into SHELTER again, the order of "each straight line with 4 same color ball" has been broken to confused state. Now, a challenge is ahead of you, you often successful in this line but irregularly in that line, in a word, it always can not come to a satisfactory arrangement of the whole lines fluently. At the beginning, it is not easy to arrange the 5 straight lines return to initial order in short time, so please try to solve this puzzle from one line first, then completion of two, three, four even to whole lines are returned to initial order finally. At last, maybe you can analyse the mystery out, but maybe you can not solve it today; however, how about tomorrow? one month later? one year later? or ten years later you may still continued to challenge to it singlely and unwilling. @end(verbatim) P.S. I @i(tried) to proofread this, but as you can see, it was difficult. -------
