Seven puzzle games, each with two hundred puzzles to start and no advertising anywhere in them.
They share the same rules about your attention and your data: nothing interrupts a puzzle, nothing expires, nothing is tracked, and there is no subscription in any of them. What differs is the puzzle — pick whichever kind of thinking you are in the mood for.
Coming soon
Classic Sudoku, endlessly generated.
Every puzzle is generated on your device and graded by the techniques it actually needs — not by counting how many digits it starts with. No ads, no timer nagging you, and a hint button that names the next move instead of making it for you.
Available now
American-style crosswords, 9×9 to 15×15.
Fully-checked American-style grids with straight definition clues — no cryptic wordplay, no misdirection. Every single letter belongs to both an across and a down answer, so there is never a letter you can only get one way.
Coming soon
British-style quick crosswords.
Lattice grids and straight definition clues. Fewer crossings than an American-style puzzle, which changes how you solve it: read for the answer first, and treat the crossing letters as the check rather than the method.
Coming soon
Word Search with clean controls.
Drag through a word to find it. Words are spread across the grid rather than stacked into crossings, and Easy hides nothing backwards — which makes the step up to Medium the biggest single jump in the game.
Coming soon
Draw through letters to form words.
Drag through a circle of letters to spell words and fill the list. Every word uses the same set of letters, there is always one that uses all of them, and anything valid you find off the list still scores and earns hints.
Coming soon
Word Circle with a crossword twist.
The same letter circle, but the answers land in a crossword grid instead of a list. The empty grid tells you how long every answer is and where they cross before you touch a letter — which turns slot length into something you can solve with.
Coming soon
Classic picross logic puzzles.
Numbers around the edge tell you the runs of filled squares in each line. Work out which is which and a picture emerges from the grid. Pure deduction — there is nothing to guess, and nothing you need to know in advance.
Not fewer ads, not optional ads, not a "rewarded" video in exchange for a hint. There is no advertising code in the app at all, so there is nothing to interrupt you, nothing to accidentally tap, and nothing that starts appearing later once you are invested.
The Android advertising ID is absent from every one of our binaries, and none of them asks permission to read it. That is checked automatically on every release build before it ships — it is a property of the artifact, not a promise in a policy.
No name, no email address, no phone number, no contacts, no location. When you sign in, the platform offers the app your display name and avatar; the app never reads them.
Your identity with us is a one-way salted hash, computed separately for every game. The same person playing two of our games is two unrelated IDs, and we could not connect them if we wanted to — we removed the ability rather than promising not to use it.
No subscriptions. No expiring content. No energy timer, no "come back tomorrow", no currency to top up. You buy a puzzle pack and it is yours, on every device you sign in from.
Anonymous gameplay measurements: how long a puzzle took, whether it was finished, how many hints it needed. We use them to check that a puzzle labelled Hard is actually hard. Saying that plainly is stronger than implying nothing is measured — the privacy policy spells out every field.
You should not have to take our word for any of it. See the receipts
