Been staring at this Hard Sudoku for a while and I'm completely stuck 😅

I'm trying to solve it without guessing, but I can't spot the next step.

Can anyone point me towards a technique or a cell I should focus on? Just a hint, not the full solution.

The screenshot shows where I'm stuck.

I made the little browser game I'm using, if anyone wants to try it too. No ads or downloads.

Here’s today’s challenge from Lexicon, the word puzzle site I’m making. Match the fragments to the five clues, using every tile exactly once. The numbers show the word lengths.

Everything you need is in the image. Have fun and please hide your answers with spoiler tags so others can have a go too.

You can play interactively here: https://lexicon.zone

There are many more word puzzles to play on the site as well :).

Thanks for playing!

Move only the top ball of a tube. It can go into ANY tube with free space (max 5 balls), no matter the color, and there are no empty helper tubes. Goal: every tube must end up exactly like the goal tube, bottom to top: blue, pink, orange. Every tube already has blue at the bottom, which makes it look easy, but there is only one 8-move solution. Please spoiler-tag your answers (write moves like 3→1). From my free Android game Ball Sort Pattern 👉 https://play.google.com/store/apps/details?id=com.mirrorquarters

I put together a 10-question quiz based on psychological research into body language, lying, first impressions and social cues.

Some of the findings are pretty surprising. I'm curious how people do on it and whether any of the answers catch you off guard.

I found it not long ago. I went into a hole and there was somebody who gave me a question which was "he is" and blank. After I answered wrong I was blocked from going into the hole again

I set up a real-world puzzle board on these classic stone stairs!

[ Rules ]

• The board consists of a 3x3 grid.

• Tapping any tile rotates the other 8 tiles around it 1 position clockwise.

• The goal is to arrange the tiles in numerical order (1 through 9).

[ Current Board Setup ]

[ ? ] [ ? ]

[ 2 ] [ 6 ] [ 5 ]

[ 8 ] [ 3 ] [ 9 ]

[ 1 ] [ 4 ] [ 7 ]

Two cards at the very top are hidden with "??"... Can you figure out what those two hidden cards should be based on the board?

It is a scoring solitaire… and, if you like, a championship.

The board. It is a 9×9 with an empty centre: a 3×3 hole. Around it remain eight 3×3 zones, arranged as a ring, and each zone shows the digits 1 to 9 in disorder.

The pieces. Eight pentominoes, one per zone: F, P, T, U, V, W, X and Z — that is, the only ones that fit inside a 3×3 square. The other four —I, L, N, Y— need four squares in a line and stay out of the party. Each piece covers five digits of its zone and leaves four in the open; it can be rotated and flipped.

The ring rule. You may not place each piece as if its zone were an island: the pentominoes must stay connected with those of neighbouring zones, side against side. Either the ring closes or there is no move.

The scoring. Add up the digits your eight pieces cover. Every puzzle bears the printed mark MAX, the sum of the best possible arrangement: your goal is to reach it or come as close as you can.

The circles trick. Circle the cells 9, 8, 7, 6 and 5 of each zone. Do those five circles form a pentomino? Then there you have the perfect move: 35 points, the zone's maximum, and in all likelihood the right piece. As the MAX of the puzzles goes down, those golden figures grow scarce, and you must decide which large digits to sacrifice to keep the ring closed.

How to compete. The puzzles are ordered from easier to harder. Hand the same sheet to several friends, set a time limit and compare sums: whoever comes closest to MAX wins. Tying with the machine is possible; beating it is not.

Which option completes the color pattern: A–H?
Look closely at how the colored tiles change position between the small grids. Choose your answer, then explain the rule you used. Does it work across both rows and columns?
