What it is
A logic puzzle where the hard part is what you throw away
Most deduction puzzles hand you every clue and ask you to combine them. Stallwise makes you choose your clues first, one stallholder at a time, before you know which of them you will need.
Two clues, keep one
Every stallholder you identify offers two clues about the rest of the market. One of them goes with you; the other is put away. Some clues settle a neighbour on the spot, some only start to matter three stalls later.
Never a guess
The game accepts an answer only when the clues you kept prove it. A trade that is merely possible is refused, and a refusal is counted. Every puzzle can be finished by reasoning alone.
A way back, at a price
Kept the wrong clue and nothing more can be proven? I’m stuck brings a put-away clue back. It costs a recall, and a perfect solve has none. If something could still be proven, the first press says so for free.
One daily, the same for everyone
A new puzzle each day at your own midnight, easiest on Monday and hardest on Saturday. Your streak counts the days you kept up.
Notes on every card
Cross out the trades a stallholder cannot have and watch the possibilities shrink. Notes are yours alone: the game never checks them and never corrects them.
Share without spoiling
A finished daily copies as a row of marks — one per clue choice, showing where you needed a recall — with your time. It says how you did, and nothing about the answer.
How a puzzle goes
Four things happen, over and over
-
One stallholder is known
The puzzle opens with a single card face up. You also know the count: three bakers, three fishers and three smiths on the small board, four of each of four trades on the large one.
-
They offer two clues, and you keep one
Tap a clue to see who it talks about, then keep it. The other is put away. You can stop and make notes on the cards before you decide.
-
You prove who somebody else is
Tap a card, name its trade. If your clues prove it, the card turns over and that stallholder offers two clues of their own. If they do not, the game says whether it was unproven or ruled out.
-
The last one needs no clue
When one stallholder is left, the count names them. A solve with no recalls is a perfect solve.
The market
Four trades, and many kinds of clue
The small board has bakers, fishers and smiths; the large one adds tailors. Each trade has its own colour and its own shape, so the board reads without colour too.
Clara and Dov share a trade.About two stallholders
Alma has exactly two baker neighbours.About the stalls around one
The middle row has exactly one fisher.About a row or a column
All three bakers are in the same column.About a whole trade

No two tailors are neighbours.About how a trade is spread
A clue that simply names someone’s trade appears in the very first puzzle and nowhere after it. A stallholder never offers a clue their own trade already answers.

Made for a phone held in one hand. A light theme and a dark one, a larger-text setting, and nothing on the screen that is not part of the puzzle.
Ways to play
A daily, a larger daily, and as many more as you like

Nine stallholders, three trades, a few minutes. The same puzzle for everyone that day, with a streak for keeping up and a result you can share.
FreeThe 4×4 daily
Sixteen stallholders and four trades, for when the small board has stopped being hard. It opens once you have solved three puzzles on the small one.
FreeEndless
Four hundred puzzles on each board, graded and sorted from easy to hard. Pick how hard you want it and get one you have not solved yet.
PremiumThe archive
The dailies you missed, sixty days back. A daily solved late counts as solved, and does not count towards a streak.
PremiumA three-lesson tutorial plays on first launch and can be played again from Settings. A hint points at the clues to look at next — never at the stallholder, and never at the answer.
