NeuroDual - Working Memory

77 games to work your mind, in one app: Dual N-Back and its variants for working memory, attention challenges, 40 logic puzzles (sudoku, minesweeper, nonograms…), crosswords and more word games. No ads, no subscription, and everything works offline. WORKING MEMORY • Dual N-Back: each turn, a square lights up and a letter is spoken. Say when either one matches the one from N turns back, at the N level you choose. • Its variants: six shapes drawn from 200 (N-Back Infinity), a line to trace from the square that lights up to the one from N turns back (Trace N-Back), and a mode that follows the rules of Brain Workshop. • Squares that light up one after another, to play back in order or in reverse (Corsi blocks), and letters to remember while you check sums (Operation Span). ATTENTION AND FOCUS • Word or color? The word BLUE on a red card: read the word or name the color, as the rule says, without falling for the trap. That's the Stroop test, in six versions: colors, voices, positions, detail or whole, and durations you see or hear. • Follow several balls among moving decoys, then pick them out when everything stops. • Tell which way the middle arrow points when its neighbors point elsewhere (Flanker), and answer the color without being pulled by the side it shows up on (Simon). 40 LOGIC PUZZLES Simon Tatham's entire collection: sudoku, minesweeper with no guessing, nonograms, slitherlink, hashi, akari, the sliding puzzle, peg solitaire, Galaxies, Tents, Towers, Net, Dominosa and many more. Every game has its own lesson, hints come one step at a time, and the grids never run out. Plus Sokoban, Gridlock (get the red car out), Restack and Lights Out. WORDS AND NUMBERS Crosswords, Mystery Word (one hidden word, six tries), Word Ladder, Letter Grid and Word or Not (real word or made up?), playable in 17 languages. Plus the soroban abacus, grade by grade, and Slabfuse, a 2048 with a few twists. TIMING, PERCEPTION AND DRAWING Say whether a duration was short or long, slide for exactly the time asked, spot the longer of two lines that flash by, find the differences between two grids, draw in a mirror. A SESSION READY EVERY DAY Guided mode puts together a short, varied session at your level. The Lab opens all 77 games with every setting: level, speed, number of targets, length. Each game starts with a short hands-on lesson, then the levels climb as you do. You will get better at these games, and you will see it: your history keeps your levels, scores and times, game by game. PRIVATE AND OFFLINE No account, no ads. Your history is saved on your device, every game works offline, and anonymous usage statistics, which you can turn off in Settings, help us improve the app. ONE PURCHASE 90 minutes of play for free, no sign-up, to try everything. After that, a single purchase through the App Store unlocks NeuroDual for good, with every game and its updates, and no subscription. You can restore it at any time from the app. NeuroDual is made by an independent developer, and the app lives on that purchase.
