This month's $100 question (not a real prize) ****A big one to celebrate my half-century (50th puzzle)!**** I work as a puzzle setter at FakePuzz (not a real magazine). This morning I burst into the office of Eddie Tor (not a real editor) so fast that I bumped against - and smashed - an expensive vase (a real one, unfortunately). "I've finished compiling this month's$100 prize crossword at last!" I exclaimed. "Let me tell you how it works..."

The puzzle is actually a combination of four different puzzle types in one grid: a criss-cross, a quizword, a codeword, and a three-to-one.

All four sub-puzzles need to be solved to find the answer to the contest question, "Whose grave am I visiting?"

"The coloured cells are obviously important...?" Eddie ventured, uncertainly.

"The letters within them are, yes," I replied. "And in addition to those, each 'coloured zone' within the puzzle contains a further concealed clue, hidden somehow within it. The first person to solve the puzzle and send in the correct name wins the $100!" "Which is absolutely, definitely NOT A REAL PRIZE," stated Eddie. "Indeed," I said. "Maybe we can send them one of our souvenir green checkmarks in the post instead..." TASK: Solve the full puzzle (collaboration permitted) and give me the answer to the question, "Whose grave am I visiting?" The answer is the name of a person of historical interest. Oh, and just in case it wasn't obvious from the tongue-in-cheek flavourtext, THERE IS NO ACTUAL$100 PRIZE! (Sorry...)

ACCESSIBILITY

Colour-blind-friendly version available here. B=Blue, G=Green, O=Orange, R=Red and Y=Yellow. Two different shades (black/grey) have been used for the blank spaces alternately across the four quadrants to aid differentiation between the four sub-puzzles (puzzles do invade each other slightly - this can be used to your advantage...).

A .xlsx version of the blank puzzle grid is available via filedropper.com to make it more convenient to solve (nobody wants to copy out a puzzle this large manually...).

• This has taken two months of painstaking labour to create. I have gone over it in microscopic detail so many times to ensure there are no more errors within it (trust me, they cropped up pretty easily in a grid this size), but if you do find anything you perceive to be an error let me know in comments and I will fix it sharpish! Thanks, and I hope you enjoy :) – Stiv Jul 21 at 22:51
• Wow, great puzzle! – hexomino Jul 21 at 22:58
• Ooh, this is interesting. Going to give it a shot now. – Deusovi Jul 22 at 0:09
• As a wise pair once said, "I am not worthy." Looking forward to this one! – Jeremy Dover Jul 22 at 0:20
• Well I expect Deus to solve the rest from here but this was really fun to solve for the bits I managed!!! Very nice puzzle :) even if there is no 100 prize, I may add a 100 rep bounty prize instead when I can because this puzzle deserves it! (Although Deus probably doesn’t need the extra rep :P ) – Beastly Gerbil Jul 22 at 1:16 2 Answers Part 1: The Solved Grid The solved grid is below: The logic for the left side portions was relatively straightforward. There were no particularly difficult steps - just searching for the next place progress can be made, like solving a jigsaw puzzle. A few sections had extra information that seems important: The criss-cross had four unused words: BLUR FOXES REPEAL MASSAGE. Change one letter in each of these words to get BLUE BOXES REVEAL MESSAGE... that looks important. We'll come back to that later. The key for the codeword was FINDCOVERTMAPBZGYHXJWKULSQ. We can see another message in the first half of the key: FIND COVERT MAP. The four dotted cells in the quizword are W, S, N, E. These are oriented to make a compass - probably to do with the "covert map" mentioned earlier. There are some letters in the three-to-one that are in all three possible words -- you can fill them in without looking at the grid. These spell out OVERLAY. Part 2: The Messages The blue boxes spell a message, in grid order. This message is: PUT ALL FOUR RIGHT WAY ROUND WHO IS MOST RENOWNED RESTING IN THE PLACE YOU FOUND So, let's do that! All four sections of the grid can be put "right way round" by rotating them and aligning their 2x3 rectangles. And the colored cells haven't been used yet - this is likely when they become important. When we rotate and overlay all four sections of the puzzle, using the compass to determine our alignment, something appears! (The missing grid lines are an artifact of image editing.) Ignoring the blue cells (since we already used those), we can clearly see some words being spelled out: ARCH, NORTH, FRONT, SECOND, CHURCH, MARKET... - could this be the "covert map"? Looking up some of these street names gives us an area in Philadelphia, where the streets are exactly the pattern of colored squares: And right at the location of the 3×2 boxes is the grave of Ben Franklin! (Confirmed by the fact that this is a "100 question", and Ben Franklin is the person on the hundred dollar bill!)

• As expected, you’re just too quick! :P Very nice solution +1, and if I add a +100 bounty when available you definitely deserve it (even if you don’t need it :) ) – Beastly Gerbil Jul 22 at 1:28
• Wow :) I posted this just before going to bed, and I wake up to find it completed! Cracking job! This is of course correct, although there were still two extra hidden hints you didn't need: 1. The three-to-one solution in the answer by @BeastlyGerbil contains a pertinent phrase (see my comment on his answer) which if explored will reveal a 7-letter word, and 2. there are technically five 'coloured zones' once you count the blue! It might have all seemed like flavourtext but that central blue box (and the title!) contain one final reference which would remove any ambiguity... Can you see it?! – Stiv Jul 22 at 5:58
• @Stiv I have a guess for the answer to (1), but I'd have to go through and actually figure it out. As for the blue, I see that "\$100" is meant to be a hint - is that what you're referring to? – Deusovi Jul 22 at 6:08
• (1) Maybe let BG pull that one out then - or you can guess the word from the stray letters in his image (clue: it's spelled backwards and just acts as an extra clue to the method of the next step you already did), and (2) absolutely - I used that precisely in case there was any quibbling over who was 'most renowned' seeing as there's a few others of his time in the same spot! – Stiv Jul 22 at 6:10
• Completely complete! The checkmark is yours - congrats on another slick solution! :) – Stiv Jul 22 at 6:42

Partial: Criss Cross and Three to one solved

(There are three letters missing to the right of ‘Three to one’ that I can’t yet place without solving the bottom right area)

Three to one:

Criss cross:

However I know that Deus has all four parts and is looking at the next steps so I expect this to become obsolete :) Still very fun to solve!!!

Edit: congrats Deus as expected!

Quick bit of logic for how to get these grids:

Three to one:

Filling in letters that are definite (i.e. all three words have this letter in the same place) and looking at the possibilities for the middle allows us to deduce some words...

Furthermore, the ‘definite’ letter spell out ‘OVERLAY’ backwards, which is useful for Deusovi’s answer

These words allow a chain to be placed with very little logic needed...

However getting into the bottom corners we need a bit more thought to try and work out which words are possible. Doing so allows more to be placed...

Placing more words gets us to a position where we have to start looking up at the criss cross section. However doing so allows us to finish off the grid, except for the couple of words to the right.

Criss cross:

Some words can be placed from the crossover from three to one...

This allows the bottom right to be solved...

Now we can move round to the left and solve that side...

Almost all words have been used now so there’s very few options left. We can now solve the rest!

• Sorry it looks scruffy, solving on mobile. I can try and ‘clean up’ tomorrow :) – Beastly Gerbil Jul 22 at 0:35
• You answered pretty fast, considering the complexity of the riddle :) – risky mysteries Jul 22 at 1:12
• @riskymysteries I’ve managed to solve two quarters, but I know there’s others who have the whole grid solved, so in reality I’ve really not been that fast :P – Beastly Gerbil Jul 22 at 1:14
• Great job BG :) And here's a piece of good news for you: You inadvertently spotted the three-to-one hint that @Deusovi didn't! Can I return your attention to "Filling in letters that are definite (i.e. all three words have this letter in the same place)"... What letters were they?? – Stiv Jul 22 at 5:53
• @Stiv I see Deus has found it, I’ll add it in anyway :P Great puzzle!!! – Beastly Gerbil Jul 22 at 10:31
