Why are we building FUMBO?

Sudoku is one of the best workouts for the mind. Too many apps turn it into a chore: ads in the middle of a puzzle, hints that just hand you the answer, a game-over screen when you slip. We are building the one we would want to play.

Think. Play. Learn.

Fikiri. Cheza. Jifunze. A good puzzle should leave you sharper than it found you, so FUMBO teaches the logic as you play.

Swahili first

Rules, hints and lessons in plain Swahili, so you never have to translate a puzzle in your head.

Free and fair

No ads mid-puzzle. No paywall on dark mode. No game over. A mistake gets the rule and where to look.

Sudoku is just the start

FUMBO is meant to grow into a home for brain games in Swahili. We are starting with the one we know best.

Who is it for?

Anyone who likes to learn Swahili, and anyone who likes to think in it. Grew up speaking it? Sharpen your mind in your own language. Just starting out, from Nairobi to Nanjing? Pick up Swahili words one puzzle at a time. No textbook, no pressure.

Never played Sudoku?

Start from zero. A short guide, then a gentle first puzzle with help at hand.

Know the rules, hit a wall?

Get a nudge, not the answer: first where to look, then why.

Short on data or storage?

Built to be a small download that plays with no connection. Perfect for a daladala ride.

Curious minds of any age

Students, parents, grandparents. If you enjoy thinking, there is a puzzle for you.

Play in Swahili. Learn Swahili.

Every puzzle is a tiny Swahili lesson in disguise. If you speak the language, FUMBO gives your mind a daily workout in it. If you are learning it, the words, the logic and the little phrases are meant to stick, because you use them instead of memorising them.

These language features are our aim, not a promise of results. The Swahili text is still awaiting review by native speakers.

For learnersA new Swahili word every puzzle

Solve the grid and the middle row spells a Swahili word, shown with its meaning. Learn one word at a time, and say it out loud.

For learnersHints that teach words

Hints repeat short, simple phrases: safu mlalo (row), safu wima (column), eneo (box). You learn the words by using them.

For everyoneAn English helper when you need it

Stuck on a word? Switch to English, get unstuck, switch back and try again in Swahili.

For Swahili speakersLogic in your own language

Puzzle and maths words are easy to leave in English. FUMBO says them in Swahili, so reasoning in it feels natural.
