What changed

Version history

1. 0.20.02026-09-08
   • AddedTen badges on the record page — finishing your first, every size, a 30×30, seven days in a row, a 10×10 inside a minute, and more
   • ChangedBadges you have not earned still show, with how far along you are. Knowing what is left is the point
2. 0.19.02026-09-08
   • AddedEarlier months are listed on the monthly page — boards finished and total time, newest first
   • AddedYour record page counts the days you solved in each month
3. 0.18.02026-09-08
   • AddedEach technique page now has a line to try yourself — mark the squares the rule settles, then check
   • ChangedNothing checks your answer against a stored key. The rule is run in your browser on the spot
4. 0.17.02026-09-08
   • FixedThree pages slid sideways on a phone — the board, the printable sheets and the technique diagrams. All three stay put now
   • FixedThe site had no icon and no ads.txt. Both were simply missing
5. 0.16.02026-09-08
   • AddedThis month's three boards — 10×10, 15×15 and 20×20, the same three for everyone, with a total time once all three are done
   • ChangedSolve a board again and only your faster time is kept
6. 0.15.02026-09-08
   • AddedA record page — days in a row, a calendar of the days you finished, and your best time at each size
   • ChangedNothing there is uploaded. A different device, or a cleared browser, starts from zero — there is no account to restore from
7. 0.14.02026-09-08
   • AddedToday's puzzle — one picture a day, the same one for everyone, chosen by the date and nothing else
   • AddedYour run of solved days is counted. It stays in your browser and is never sent anywhere
   • ChangedToday's grid is built in your browser, because a page baked yesterday cannot know what day it is for you
   • FixedFinish yesterday's puzzle after midnight and it counts for yesterday, not today. Today's puzzle stays unsolved, as it should
8. 0.13.02026-09-08
   • AddedA printable page — six puzzles from 10×10 to 20×20, one to a page, answers at the back
   • ChangedThe answers print grey rather than black. A 20×20 filled in solid black soaks the paper and empties the cartridge
   • ChangedPrinted puzzles carry a number, not a name. The name would be the answer
9. 0.12.02026-09-08
   • AddedA page about the picture library — how many at each size, how they are checked, and what makes a drawing fail
   • AddedYou can jump straight to a size from that page
   • ChangedThere is deliberately no page for each picture. A drawing's title is its answer, and a list of them would give the game away
10. 0.11.02026-09-08
    • AddedA page for each of the six rules — when to look for it, the line it fires on, and why it holds
    • AddedThe rule a hint names is now the title of a page you can read. They were separate things before
    • ChangedTwo rules cover 98 of every 100 steps across the 175 pictures. The table says which
11. 0.10.02026-09-08
    • AddedA page on where to start — the first move, why you cross off before you fill, and what to do when a grid stops moving
    • AddedThree pictures walk one small puzzle from an empty grid to a finished one
12. 0.9.02026-09-08
    • AddedA rules page. Four pictures cover the whole rule set — what a clue counts, why crossing off matters, when a line is done, and what you end up with
    • ChangedThe numbers in those pictures are worked out from the pictures themselves, so they cannot drift out of step
13. 0.8.02026-09-08
    • AddedThe grid works from the keyboard — arrow keys move, Space fills, X crosses off
    • FixedScreen readers were told the grid had rows and columns it did not have. Each square now names itself instead, and a change is announced once rather than square by square
14. 0.7.02026-09-08
    • AddedA settings block under the board. It remembers your choices in this browser
    • AddedClues of a finished line fade out, so you can see at a glance which lines are still open
    • AddedCopy link hands you the address of the picture you are on
    • AddedClue numbers get crossed off once their block is definitely placed — counted from the ends inward, never guessed
    • AddedOptional square counter and a mark on the square you just changed
    • AddedClues can be repeated on the right and along the bottom, so your eye does not have to cross a 30×30 grid to read them
15. 0.6.02026-09-08
    • Added175 pictures now — 30 at every size from 10×10 up, and 25 at 5×5
    • Changed5×5 stays at 25. Twenty-five squares only hold so many things you can still recognise
16. 0.5.02026-09-08
    • Added150 pictures now — 25 at every size. New ones include a bee, a turtle, a dolphin, a windmill and a fishing boat
17. 0.4.02026-09-08
    • Added120 pictures now — exactly 20 at every size from 5×5 to 30×30
    • ChangedNew subjects at every size: a fox, an owl, a dice, a pine tree, a rocket and fifteen more
18. 0.3.02026-09-08
    • Added100 pictures now, and every size from 5×5 to 30×30 has at least 16 of them
    • ChangedThe larger sizes used to hand you a machine-made shape that finished without a name. They are real pictures now
    • ChangedMost of the set solves with the overlap rule alone, so almost every puzzle reads as Easy. Harder pictures are next
19. 0.2.02026-09-07
    • AddedPuzzles are hand-drawn pictures now — 32 of them at 5×5, 10×10 and 15×15. Solve one and it tells you what you drew
    • ChangedNew puzzle never gives you the same picture twice in a row
    • Changed20×20 and larger are still machine-built shapes, so they finish without a name. Pictures for those sizes are coming
20. 0.1.02026-09-07
    • AddedThe board is here. Pick a size from 5×5 to 30×30, fill squares with the left button and cross them off with the right
    • AddedHints name the rule they used — overlap, gap too small, out of reach — and light up the line it was read from
    • AddedEvery puzzle is checked before you see it. If line-by-line logic cannot finish the grid, the puzzle is thrown away and another is built
    • ChangedDifficulty comes from which rules the puzzle needs, not from its size. A 30×30 can be easier than a 10×10
