Great for building spatial reasoning and logic skills! Sudoku School is the perfect sudoku app for kids and other sudoku beginners. It teaches you to play using 4x4 and 6x6 puzzles that are much simpler than the usual 9x9 sudoku puzzle. It also has an in-game help feature that explains the rules clearly with drawings and simple text. The game tiles have both numbers and colors, so younger players can use the colors for help until they get comfortable using the numbers. Ten puzzle levels cover a huge range of difficulties, from the easiest 4x4 level, which is perfect for younger kids, to the expert 6x6 level which is almost as hard as regular sudoku. This means the game can grow with you for a long time while you progress. Once you have mastered all the levels in this app, you are ready to graduate to regular sudoku! Multiple user accounts make it easy to share--perfect for families or for the classroom. • Easy to use drag and drop puzzles • Colored tiles to help beginners • Ten levels of difficulty • In-game explanation of the rules • Trophy wall to celebrate progress • Score tracking for multiple users • Six puzzle themes • 5000 puzzles available (20 puzzles are free) We made sudoku school free to download so that you can test it without having to buy anything.

Unlock the Magic of Reading with READING MAGIC 3! Transform your child into a confident reader with READING MAGIC 3! This app makes learning to read an exciting adventure through interactive activities focused on short vowel words containing multiple syllables. Meticulously designed to provide an advanced boost to your child’s phonemic awareness, this app combines three foundational pillars of literacy science into one powerful, interactive ecosystem: Blending (Listening), Segmenting (Speaking), and Decoding (Reading). Grounded firmly in Science of Reading principles and utilizing University of Florida Literacy Institute (UFLI) guidelines, READING MAGIC provides specific, precise training with extensive repetitions to help young brains bridge the gap between spoken sound units and complete words. IDEAL FOR BOTH BEGINNING PRE-READERS AND STRUGGLING READERS For Beginning Pre-Readers: A stress-free launchpad. By practicing words through pure sound sequences first, your child masters the internal mechanics of reading without cognitive overload. This keeps them from being frustrated by trying to learn separate, difficult skills at the same time. For Struggling or Remedial Readers: If your child's reading is hesitant or choppy, or if they guess at words, this app provides the targeted intervention recommended by modern reading science to help young brains bridge the gap. THREE CRITICAL SKILL-BUILDING PILLARS While many phonics programs completely overlook the auditory mechanics of reading, our program systematically guides your child through the complete progression of decoding: Skill 1: Blending (Listening): Interactive listening activities train your child’s neural processing ability to hear isolated sounds in words and join them together mentally. This builds the vital auditory runway required for future fluency. Skill 2: Segmenting (Speaking): True spelling and reading independence require the ability to pull spoken words apart into their individual sound units. These exercises build explicit awareness of the acoustic structure of language. Skill 3: Decoding (Reading): The ultimate bridge to literacy. Your child applies their mastery of blending and segmenting directly to text, smoothly moving from spoken sounds to visual words. STRUCTURAL SPACING & INSTRUCTION (Science-Backed Layout) Our app builds the actual findings of reading science directly into the user interface for maximum visual clarity: Anti-Crowding Design: Peer-reviewed research, including Marinus et al. (2016) and Wery & Diliberto (2017), demonstrates that generous letter spacing is critical for early decoding. By placing each letter on its own isolated card with distinct physical gaps, our layout eliminates visual crowding, allowing your child to isolate each sound unit cleanly. True Comprehension: The app strictly discourages picture guessing, forcing children to rely purely on their decoding skills to foster true comprehension and build lasting confidence. INDEPENDENT LEARNING & AESTHETIC SIMPLICITY Distraction-Free: Our minimalist design eliminates overstimulating audio-visual clutter, excessive sound effects, and animations to keep your child entirely focused on the mechanics of reading. Stress-Free Growth: Built-in natural feedback loops offer gentle corrections, nurturing self-discovery and independent learning at your child's own pace. EXPERT RESEARCH BACKING "Before a child can read fluently with their eyes, they must be able to blend fluently with their ears. Weakness in auditory blending is one of the strongest early predictors of later reading failure." — Dr. Joseph Torgesen, Florida State University. "Teaching students to blend and segment benefited their reading much more than did a multiple-skills approach... and teaching phonemic awareness with letters created effect sizes almost twice as large as teaching children without letters." — The National Reading Panel (NRP) Meta-Analysis
