5/31/2021 - MATCH PLAY
The grid contains matches of different sizes, any of which may be completely unburnt, partially burnt, or completely burnt. Matches burn from the head (rounded end) to the tail, without skipping segments. The numbers outside the grid indicate the number of burnt segments in the corresponding row or column. Can you shade in the burnt segments to “match” the numbers?

Correct! Here’s another way to show the solution.

Summary

so they burn from the head towards the tail, but are not required to burn all the way to the tail? I couldn’t figure it out because I was assuming that the whole match burned all the way and nothing worked.

Correct, the entire match doesn’t have to burn (and doesn’t in most cases). We did this type of puzzle earlier, it was the 2/2/21 puzzle, posted on 5/13. You can search for “Match Play” in this thread to find it, if you want to try another one, or look at the solution for one to understand how to do the other.

In each string below, change one letter every time it appears to a different letter to create a common eight-letter word. For example, change every G in GOGENTUG to M to create the word MOMENTUM. the eight pairs of letters, like GM in the example, will describe you.

Both of you are correct!

6/2/2021 - ARITHME-PICK
Place one of the four basic arithmetic operations (+,-,x,/) in each blank to make a correct equation. Symbols may be repeated; you do not have to use all four. All operations are performed from left to right, ignoring mathematical order of operations. The result at each step must be a positive whole number. What is the equation?
Equation: 3 _ 6 _ 2 _ 7 _ 8 = 16

Bonus points if you can find an alternative solution that doesn’t require positive whole numbers at each step.

Summary

3 * 6 / 2 - 7 * 8 = 16

alternate 6/2

3 / 6 * 2 +7 +8 = 16

mathematical order of operations is equivalent to left to right operations

Just because I could I used Excel to show all 256 possible combinations (4^4 possibilities).

Summary

3-6+2-7-8= -16, which I thought was fun
3-6-2+7 * 8 = 16, but results in some intermediate negative integers
3*6/2-7 * 8=16, actual solution as posted by OldTimer
3/6 * 2+7+8=16, but results in an intermediate non-integer number

3-6 * 2 * 7 * 8=-336 is the smallest number you can get
3 * 6 * 2 * 7 * 8=2016 is the largest number you can get
You could have done this same challenge with a lot of different numbers (unique solutions given the constraints): 1,2,3,5,6,9,12,14,15,22,24,26,31,32,33,37,41,51,55,57,69,71,72,85,88,112,118,120,128,132,134,144,148,184,200, etc.)

If you could add in parenthesis I’m assuming there are even more different ways you could solve this.

The first matches puzzle was easy to screw up and I thought after doing that that this one would go better, but that’s not the case. I got to 4 squares left and two choices that worked, so I screwed up somewhere. I feel like I need to do it again.

Yeah, those match puzzles are deceptively hard. I think I got the first one, but struggled with this second one.

Fit the pieces into the frame to form common, uncapitalized words reading across and down crossword-style. There’s no need to rotate the pieces: They’ll fit as shown, with each piece used exactly once.
