Blindfold Sudoku Mini vs Trace Memory Game

Blindfold Games are entertainment apps provided as a service to the visually impaired community by Objective Ed. Your in-app upgrades pay for the development and support of these games.  Sudoku Mini is a fully accessible Sudoku game for both sighted and visually impaired people, designed for rapid audio play. It's a starter game for Sudoku - a 4-by-4 puzzle game that's great for kids and adults just getting started with Sudoku. Sudoku Mini comes with 5 Sudoku 4-by-4 easy puzzles - and is controlled through gestures. It doesn't require voice-over but is fully compatible with voice-over. More puzzles are available through an in-app purchase. The Sudoku puzzle board is not visible; instead, you play by listening. Tap on a cell to hear what's in the cell, swipe right to hear the row, swipe down to hear the column and swipe up to hear the square. Blindfold Sudoku gives you audio cues to tell the difference between the initial puzzle cells and the cells you fill in, and it lets you set multiple candidates for a cell. You can set the game to use numbers, or animals (dog, cat, horse, or frog) or animal sounds.

A shape flashes on screen. You have to redraw it from memory — in the same place, at the same size, before time runs out. Trace is a memory recall game. Every round walks through three phases: memorize, recall, score. The shorter the flash, the harder it gets. From a generous three-second look on Beginner to a brutal 0.3-second flash on Master, every recall tests your visual memory and your motor precision. WHAT YOU GET FOR FREE - 15 hand-tuned Basics shapes — circles, stars, infinity loops, hearts, spirals, more - Daily challenge: same shape worldwide every day, with a daily streak that builds across days - All six difficulties: Beginner, Easy, Medium, Hard, Expert, Master - The full scoring breakdown — shape match, position match, scale match — shown after every round so you understand exactly why you scored what you did UNLOCK TRACE PRO ($2.99 ONE-TIME) - 106 more shapes across 7 categories: Nature, Animals, Faces, Zig-zags, Constellations, Symbols, and the full A–Z Alphabet - Streak mode: chain perfect recalls in a single run with a combo multiplier that grows up to 3x. Earn zero stars on any round and the run ends. - Future shape packs and game modes included at no extra cost HOW SCORING WORKS Three sub-scores combine into your final accuracy: how close your drawn curve is to the target shape, how close your stroke's centroid is to the original position on the canvas, and how close your bounding-box span is to the original scale. Faster recalls earn speed bonus points. Recalls completed in a single unbroken stroke earn an extra +100. Stars are awarded based on your total points, capped at three. DESIGNED FOR FOCUS - One-time purchase. No subscriptions. No ads. No third-party tracking. No analytics. - Plays entirely offline — only contacts Apple's StoreKit, and only when you initiate a purchase or restore. - Phone calls or notifications mid-round automatically pause the round timer so you don't lose progress to interruptions. - Full VoiceOver support across every screen. - Dark-mode native. PRIVACY Trace collects no personal data. Game progress is stored only on your device. Your finger drawings exist only in memory during a single round and are discarded as soon as the next round begins — they're never written to disk, transmitted, or shared.
