Lumath
Daily math puzzles & streaks
Free · Designed for iPad. Not verified for macOS.
Lumath is a CrossMath puzzle: an arithmetic crossword where short equations run across and down and share the cells where they cross. Fill the blanks so every equation holds. Calm and quick at the start, genuinely hard at the top.
WHAT MAKES LUMATH DIFFERENT
• Ads you can live with. One small banner at the bottom of the screen. Never a full-screen ad, never an ad between puzzles, never one you have to watch to keep playing. Non-personalised ads are one switch away in Settings → Privacy.
• Difficulty that actually goes somewhere. Seven tiers from Beginner to Genius. Genius boards have 34 equations with up to four operands, brackets, powers, modulo, square roots, squares and factorials.
• Exactly one solution, every time. A solver checks each puzzle before you see it, so you never have to guess between two valid answers.
• Hints that teach. Nudge, Narrow and Strategy are free and never give away a number. Reveal cell and Solve line are earned by solving — never sold.
• Real players only. Leaderboards show real accounts; when nobody has played yet, the board says so instead of inventing names. Follow the players you like and race them on a Following board.
DAILY
One shared puzzle a day, the same for everyone. Keep a streak, earn freeze tokens that cover a missed day, and race the daily board. Missed one? Play any past day from the calendar and collect a trophy for a full month.
ARCADE
Endless for a quiet run with no clock. Rush to beat the timer. Streak to see how far you get before one mistake. Plus a weekly twist that changes the rules, six in rotation.
REVEAL
Every week a new picture hides behind jigsaw pieces, and each piece is one puzzle. Solve it and the piece snaps into place. Play solo, or invite family and friends into a shared canvas where every solve reveals the picture for everyone. Finish the week and the picture joins your gallery, ready to replay any time.
PROGRESS THAT ADDS UP
90 badges across seven ladders, player levels, and three daily goals. Weekly and all-time leaderboards rank by points and show how far you moved. React to another player's time with a tap.
ON THE BOARD
Pencil marks for the possibilities you are weighing, and a board filled in pencil finishes itself the moment it is right. Undo and redo. Auto-advance, if you turn it on, jumps only to a cell you can work out next. From Hard up, the tray mixes in a few decoy numbers that belong nowhere. An optional mistake limit if you want the pressure, off if you don't. Every board autosaves, so your clock, hints and mistakes survive a resume.
PRACTICE
Packs of 100 puzzles per tier and four input styles: candidate tray, type-in, operator blanks and mixed. A two-puzzle calibration finds your level.
CALM BY DESIGN
No lives, no coins, and a timer you can hide. Seven themes including Paper, Slate, Night and Sepia, plus high contrast, larger text, reduced motion, and sound, music and haptics you can switch off. Optional ambient music while you solve.
ALSO
A home-screen widget for your streak and the week's picture. Cross-device sync, so your progress, streak and best times follow your account. The daily puzzle and any pack you have opened work offline.
Available in English, German, Spanish, French, Hungarian, Portuguese, Romanian, Russian, Japanese, Korean and Chinese.

Auto-advance now follows you on a zoomed-in board: it glides to the next cell you can work out and, only when it has to, zooms out just enough to show that cell's whole equation. Turn it on in Settings → Gameplay → Auto-advance.
