About this game

Dual N-Back DaVinci is nback training built your way. Train working memory, focus and concentration with the classic n-back task, from simple Single N-Back to demanding Quad N-Back, then design your own modes when you're ready for more.

WHAT IS DUAL N-BACK?
N-back is one of the most studied working memory exercises in cognitive research. You see and hear a stream of stimuli and tap when the current one matches the one from N steps back. In Dual NBack you track a position and a sound at the same time. It sounds simple. It isn't. That's the point.

FROM SINGLE TO QUAD N-BACK
• Single, Dual, Triple and Quad N-Back
• Combine position, color, images, text and audio as stimuli
• Letters, numbers, symbols, or Japanese Katakana, Hiragana, Korean Hangul and Chinese characters
• Several audio channels at once, with a separate sound in each ear for an extra challenge

GAME MODES
• Progression: an adaptive brain training path. Do well and N goes up, struggle and it eases off.
• Ladder: climb a set of levels in one run and chase your best total score
• Timer: train against the clock
• Two Player: play with another player in one phone, or against a bot. This gives motivation to practice.
• Jaeggi mode: classic settings inspired by the well-known Jaeggi dual nback studies

CREATE YOUR OWN MODES
This is where the app stands apart from other n-back trainers. Build any training you can imagine:
• Use your own custom text, images and audio as stimuli
• Custom semantic mode: link words, pictures and sounds into your own pairs
• Fine-tune N level, stimulus interval, session length, match rates and target score
• Set the rules: demotion, error limits, score resets, how long stimuli stay visible
• Advanced options like reversed audio, text to speech and mosaic images split into fragments
• Save your presets and switch between them anytime

Learning a language? Put vocabulary into a custom mode and train memory and words in the same session.
