Fill the grid so every row, column and sign agrees. Pure logic, no guessing.
Futoshiki is a number puzzle with a twist: little signs between the cells. Fill the grid so every row and every column holds each number once, and make every greater than and less than sign come true.
Every board has exactly one answer, and you can reach it with logic alone. I checked all of them with a solver that works the way a person does, so none of them need a guess.
HOW TO PLAY
• Tap a cell, then tap a number
• Turn on Notes to pencil in the numbers a cell could still be
• Erase clears a cell, and Undo goes back as far as you like
• A placed number tidies the matching notes out of its row and column
THREE PACKS, 300 PUZZLES
Easy 4x4, Medium 5x5 and Hard 6x6, with 100 puzzles each. Easy boards teach you to read one sign at a time. Medium ones chain signs together, so a cell three steps above a 2 can't be small. Hard boards ask you to spot two cells that share the same two numbers. Nothing's locked, start wherever you like.
A DAILY PUZZLE
There's one daily puzzle, the same for everyone on the same date. It's 5x5 from Monday to Thursday and 6x6 from Friday to Sunday. Solve it each day to grow your streak. It works offline too.
HINTS THAT EXPLAIN THE STEP
Stuck? Tap Hint and the app marks the cells that matter and tells you why, like "The signs step down from here through 1 cell to the 2, so this cell is at least 4." Tap Apply once it makes sense. If a number you placed is wrong, the hint points that out first. Hints are unlimited and never come with an ad.
NO LIVES, NO PRESSURE
Mistakes don't cost you anything. With Mistake check on, a repeated number or a broken sign gets a soft red mark and a short note. Turn it off if you'd rather find your own mistakes, and the app only checks once the board is full.
EASY ON THE EYES
• Light: warm cream cells, indigo numbers and bold round signs
• Dark: a navy theme for the evening, used automatically in dark mode
• Bold cell borders for more contrast
• Reduced motion keeps the animations calm
A SHORT START
The first time you play, three tiny boards show you the line rule, a single sign and a chain of signs.
If you like sudoku or other number logic games, Futoshiki should feel familiar fast. Some people know it as Unequal or as an inequality puzzle. It's a good brain game for a coffee break: a 5x5 board takes a few minutes.
ALSO INCLUDED
• Works offline, no account and no sign in
• Half played boards, notes and best times are saved

About ads: Futoshiki is free to download and supported by ads. A small banner sits at the bottom of the screen, below the number keys. After your first few puzzles, a full screen ad may show now and then when you tap Next puzzle or Home on the solved screen. You'll never see one in the middle of a puzzle, and hints never need one.
Start with the 4x4 pack and see how much one sign can tell you.
Co je nového
Small fix for the moment you finish a puzzle. When the last number was right, the hint bar could still flash a note saying something did not fit, just before the Solved screen. Now it shows your time instead. If the board is full and something really is off, you still get the note.
