Serve one cup to every table
Brewdoku is a logic puzzle about running a small café. Every coloured table gets exactly one cup, every row and column gets one too, and no two cups touch, not even at the corners.
This is a level from the game. Tap a spot to start.

The rules fit on a napkin
Pick a rule, then tap any spot on the tray to see what a cup there rules out.
One per table
Every coloured table gets exactly one cup. Once a table has its cup, the rest of it can be crossed out.
One per row and column
Each row and each column holds exactly one cup as well. A cup claims its whole row and its whole column.
Never touching
Cups need a little elbow room. No two cups touch, not even diagonally, so the eight spots around a cup stay empty.
All three
Put the rules together and one cup rules out a lot. Every puzzle has one answer, and you never need to guess.
Nothing is timed unless you switch the clock on in Settings, and you can’t run out of lives.
Level 37, start to finish
A screen recording of the game. Double tap a spot for a cup, tap it once for an X.
When the last table has its cup, the order goes out.
300 levels, from 5×5 to 10×10
The level map is the café’s menu: ten blocks of thirty, from Espresso to Grand Café. Espresso starts on a 5 by 5 board, Grand Café ends on 10 by 10.
You don’t have to finish a block to move on. Solve ten levels in it and the next block opens.
Every level pays up to three beans. A hint or a visible mistake costs one, and you always keep at least one.
One new puzzle every day
The Daily Brew changes at midnight, and everybody gets the same one. It starts small on Monday, 6 by 6, and grows to 10 by 10 on Sunday.
Each day you brew it, your card gets a stamp. Seven stamps earn a Coffee Filter, and a filter keeps your streak alive on a day you miss. You can hold two.
Missed a few days anyway? The calendar keeps the last thirty Daily Brews free to play.

When you’re stuck
Ask the barista. A hint never just gives the answer away: first it shows where to look, and that part is free. If you want to know why, the explanation costs one hint. After that, the barista can do the step for you.
If a cup on your board is already wrong, the tip says so first, and you can rewind to your last good brew.
You start with three hints and get a free one every new day. A short video gives three more, but only when you choose to watch one.
Barista’s tip
The blueberry and lavender tables can only use columns 1 and 2. That is two cups for two lines, so every other spot in columns 1 and 2 gets an X.

How many ads, exactly
Brewdoku is free, and a few ads pay for it. They only ever show between puzzles, never in the middle of one.
- Where
- Only after a solved level. Never during a puzzle, and never after the Daily Brew.
- When not
- Not in your first session, and not in the first fifteen levels.
- How often
- At most one every three puzzles, never two within four minutes, and six in a day at the very most.
- Videos
- Only when you ask for one: three more hints, a broken streak repaired, or a Daily Brew older than thirty days.
- Gone
- One purchase removes the ads between puzzles for good and adds a free hint every day. Videos you ask for yourself stay available. It is not a subscription.
Settings worth knowing
Patterns on tables gives every table a pattern next to its colour, for colour-blind players.
Auto X crosses out the spots next to and in line with your cups. It is off until you turn it on.
Show rule breaks is on at first. Turn it off and a wrong cup is no longer marked, and then it does not cost a bean either.
Sound and vibration are soft, and you can switch either one off.
Who makes this
Me, on my own, in the Netherlands. I wanted a puzzle for the first coffee of the day that does not shout at me, so the boards stay quiet and the ads wait until you have finished.
If something feels off, or a puzzle seems to need a guess, write to me at contact@blockbrewer.nl. I read every email myself.
