A team of Japanese IT developers, driven by a passion for technology

We are Yomoe Studio, a small and focused development team. We're currently working on several apps and games — stay tuned.

• Onet Connect Tile Match: Yomoe

  Tap two, link them, watch them go. Made in Japan. This app is made by Yomoe Studio, a small studio in Japan that does nothing but build apps. No flashy effects, no nudges to spend. Our time goes into the details instead — the feel under your finger, the colours, how satisfying each match is — to make something you can pick up every day without being worn out by it. Onet Connect Tile Match: Yomoe is a tile-matching puzzle: pick two tiles with the same design, and if a path with at most two turns can join them, they disappear. The path may travel around the outside of the board, so tiles on the edge can always reach each other the long way round. Every board is generated on your own device. No connection needed — on a plane, underground, or anywhere else, your next board is already there. ■ Build your own board — Custom mode (Pro) Set the rows, the columns, the number of tile designs, and what remaining tiles do after a match. The five movement rules — stay put, fall down, slide left, slide right, gather to the centre — each turn it into a genuinely different game. Turn on the timed refill and tiles keep arriving while you clear them, which changes the pace completely. Your settings are saved, so a board you like is always one tap away. The movement rules also appear, free, in the later Adventure stages and in Challenge. ■ Six ways to play - Adventure: stage after stage, chapter by chapter, on boards in more than 20 shapes — hearts, pyramids, castles and more. Every match gives a little time back, and your remaining time decides your stars. - Classic: pick Starter through Hard and take on a single timed board. - Relax: no timer. If you run out of moves the board reshuffles itself, so you never get stuck. - Endless: tiles keep arriving every ten seconds. Clearing the board doesn't end it — how long can you hold out? - Challenge: one clock, board after board. Each board you clear buys a little time, and movement rules and incoming tiles join in as you go. - Custom (Pro): the board, the tile count, the movement rule — all yours to set. ■ Tools to keep you moving Hint (lights up a matching pair), Shuffle (rearranges the board), Bomb (removes a matching pair outright) and +30 seconds. You get a set of each per game, and you can top them up by watching a video (instantly, with no video, in Pro). ■ Achievements Combos, completed chapters, how long you last in Endless — the more you play, the more achievements you unlock, including a few hidden ones whose conditions stay secret until you earn them. Every achievement can be earned in the free version, and you can check your progress anytime in Settings → Achievements. ■ Built to be comfortable Portrait only, everything within reach of one hand. Play with Fruits & Veggies or classic Mahjong tiles (plus Numbers & Letters and Animals in Pro) — all hand-drawn vector shapes, so they stay crisp on any screen. 10 languages. ■ Pro Version (one-time purchase) One purchase, and these five are yours for good: - Every ad in the app removed - Custom mode - 4 board themes (Matcha / Sakura / Ocean / Night) - 2 extra tile designs (Numbers & Letters / Animals) - Tool top-ups and Challenge time extensions straight away, no video The other five modes, every stage, every difficulty and the Fruits & Veggies and Mahjong tiles are available in the free version from the start. The number of tools you are given, and the limits on using them, are identical either way. ■ Tell us what you think Anything you notice, anything you would like to see — send it through the feedback form in the app. We read every message that comes in, and it shapes what we build next.

• Sudoku Number Puzzle: Yomoe

  A quiet study, one puzzle at a time. Made in Japan. Yomoe Sudoku is made by Yomoe Studio, a small studio in Japan that does nothing but build apps. No flashy effects, no nudges to spend. Our time goes into the details instead — the feel under your finger, the colours, the quality of each individual puzzle — to make something you can pick up every day without being worn out by it. Yomoe Sudoku brings the feel of pencil on paper to your phone. Every puzzle is generated on your own device and checked to have exactly one solution. No connection needed — on a plane, underground, or anywhere else, your next puzzle is already there. ■ When 9×9 is no longer enough — boards up to 16×16 Challenge mode gives you five board sizes — 4×4, 6×6, 8×8, 12×12 and 16×16 — each with four difficulties. Numbers above 9 are shown as letters A to G, so no cell ever has to squeeze in two digits. Boards of 12×12 and larger can be pinch-zoomed, and a long puzzle can be saved and picked up later. Every Challenge puzzle is verified to be solvable by logic alone, with no guessing, before it is handed to you. Finishing a 16×16 feels nothing like finishing a 9×9. ■ Six ways to play - Classic: pick Easy through Expert and solve one at your own pace. - Challenge: five board sizes from 4×4 to 16×16, each with four difficulties. - Daily Challenge: one puzzle a day, the same one for everyone in the world. Stamps fill your calendar and your streak grows. - Journey: level after level, chapter by chapter — from gentle 4×4 grids up to Expert. - Speed: a timed single puzzle, plus a sprint that keeps them coming. - Zen: no timer, no mistake count. A calm, low-contrast board and nothing but thinking. ■ Help that teaches Candidate notes, row/column/box highlighting, and matching-number emphasis. When you are stuck, a hint tells you why that digit belongs there — so you learn the technique, not just the answer. Slips can be undone as many times as you like. ■ Worth coming back to Best times and three-star rates per mode and difficulty, separate records for every board size, achievements and trophies, and your daily streak. There are no leaderboards to compete on. The only one you are measured against is yesterday's you. ■ Built to be comfortable Everything within reach of one hand, a left-handed mode, and colour-blind friendly marking. 10 languages. Portrait only. ■ Pro version (one-time purchase) - No ads - Unlimited hints (free: 3 per puzzle, plus more by watching a video) - All 5 board themes unlocked (Study Paper, Night Ink, Celadon, Ochre, Bamboo Dew) The free version still gives you all six modes, every board size including 16×16, every level, and every achievement and statistic, with nothing held back. Pro only buys you an uninterrupted screen and a change of scenery. ■ Tell us what you think Anything you notice, anything you would like to see — send it through the feedback form in the app. We read every message that comes in, and it shapes what we build next.

• Kids Math, Times Tables: Yomoe

  Lots of "one more!" moments. Made in Japan. Yomoe Math is made by Yomoe Studio, a small studio in Japan that does nothing but build apps. No flashy effects, no nudges to spend. Our time goes into the details instead — how questions are paced, how big the buttons are, what a child hears after a wrong answer. Yomoe Math is an addition, subtraction, multiplication and division practice app for children who can already read simple words, up to around age 12. Every question is created on the device, so learning works even without a connection. ■ Four ways to learn - Practice: six courses — addition, subtraction, add & subtract mix, multiplication, division, and multiply & divide mix. Step by step from sums up to 10 all the way to 1000, and the times tables. - Adventure: travel through nine worlds, collecting stars as you go. Each world ends with a boss level, and later worlds add time trials. - Daily Challenge: a daily warm-up. Pick a difficulty and watch the streak grow. - Review Book: wrong answers are saved automatically and come back exactly as they were first seen. ■ Many kinds of questions Multiple choice, typing the answer on a number pad, filling in the missing digit, finding the true equation, and comparing two expressions. Addition and subtraction up to 10 come with fruit pictures as a hint. ■ Praise that keeps them going Combos for answers in a row, stars and badges. A friendly cat cheers them on, even after a wrong answer. ■ For parents - Parent Mode: a calendar of daily learning records and weekly / monthly / yearly accuracy charts for each operation. - Settings, purchases and external pages are behind a parent check (a math question). - Learning records never leave the device. No account needed. - Ads are served with child-directed settings and never appear while questions are being answered. - 10 languages. Portrait only. ■ Pro version (one-time purchase) - No ads - Full study history (the free version shows the last 7 days) - Export and share a study report - Custom practice, with the range set by a parent The free version still includes every course, every world and level, the Daily Challenge, the Review Book and Badges, with nothing held back. Parent Mode is free too, showing the last 7 days of records. What Pro adds are tools for parents — what a child can learn is the same either way. ■ Tell us what you think Send anything you notice or would like to see through the form in the app's Settings. We read every message.
