The clues are numbers.
The answer is a picture.
Every puzzle is a grid of empty squares and a margin full of numbers. Work out which squares are filled, and a small pixel picture comes out the other side.
No energy meter. No waiting. Every puzzle is open from the moment you install — and if an attempt goes wrong, starting it again is instant and costs nothing.
Tap once to fill, again to rule out.
That's a tree.
Three numbers, one picture
A clue like 2 1 means that line holds a run of two filled squares, then at least one gap, then a single one. Nothing is guessed — every puzzle in the game can be solved by reasoning alone.
Start with the certainties
A row of six in a six-wide grid can only be filled one way. Those free squares are the foothold for everything else.
Cross out what cannot be
Ruling a square out is as useful as filling one in. Undo is free and unlimited, so there is no cost to changing your mind.
The picture colours itself in
The last square you place is the one that turns a grid of marks into something you recognise. Then it is yours, and it goes on the shelf.
It remembers where you stopped
The home screen opens on whatever you were in the middle of — here, Puzzle 15 at 73 % done — with the next puzzle queued beside it, today's daily puzzle underneath, and the monthly challenge's own progress line below that.
Coins and a day streak sit at the top. Coins buy hints, a second chance and cosmetics. They never buy access to a puzzle.
Ten by ten, and room to think
Clue strips run along the top and the left, the board is divided into blocks of five so you can count without losing your place, and three controls sit under your thumb — a fill-or-cross toggle, undo, and hint — under a Lives label and its dots.
The three dots are the attempt's lives. Three mistakes end that attempt — not the puzzle, which stays open, and which you can start again straight away for nothing.
Every solve has a name
Finish the grid and the squares drop their outlines and turn into the picture they were describing the whole time. This one is called Cupcake. There are one hundred and ninety-five of them.
A shelf that fills up
Solved pictures go into a gallery, each with its own name — Birdbath, Bone, Bowtie, Candy, Crown, Garden Bench, Garden Boots, Gift, Gingerbread Man, Paw Print, Plug, Pretzel and more below. Seeing the gaps is most of the reason to come back.
The shop sells coins and convenience
A Welcome Pack bundles coins with a one-off cosmetic, a day of unlimited hints is its own line under Extras, and coin top-ups underneath come in a few sizes, each with its own App Store price button.
On iPad it is a bigger board, not a bigger phone
The iPad layout is drawn for the iPad: in landscape, the grid takes the width it is given, the clue strips grow with it, and the fill, undo and hint controls sit along the right edge, where your hand is. Your progress follows you between the two through your own iCloud account.
The plain facts
Questions
I have never played one of these. Is it hard?
The first few puzzles are five squares across and teach you the one rule you need. It is logic, not arithmetic — the numbers describe runs of filled squares, and you never have to add anything up.
What happens when I get one wrong?
An attempt carries three lives. Three wrong squares end that attempt and clear the board. The puzzle itself stays open, and starting it again is immediate and costs nothing. Undo is free and there is no limit on it.
Is there an energy bar or a timer between puzzles?
No. There is nothing to wait for and nothing to refill. Every puzzle in the app is unlocked from the first launch.
What can I buy, and do I have to?
Optional one-off items only: coins, and a few conveniences and cosmetics. There is no subscription. Coins are never needed to open a puzzle, and the pictures that unlock new areas cannot be bought at any price — they are earned by solving. Current prices are displayed in the App and on the App Store, and may vary by region.
Will my progress move to my other device?
Yes, through your own iCloud account, as long as you are signed in to the same Apple Account on both. Your saves are also kept on the device itself, so the game works when you are offline.
