Description:The Dual N-Back is a focused brain-training puzzle that challenges and improves working memory using simultaneous visual and auditory cues. Watch the grid, listen to the letters, and decide if the current cue matches the one N steps earlier. Difficulty adapts to your performance, turning short sessions into meaningful cognitive workouts. It offers dual, visual-only, and audio-only modes, a clean distraction-free interface, and configurable session length and speed. Track accuracy, N level progression, and streaks to measure improvement and stay motivated.
How to play:Focus on both the grid and the spoken letters at the same time.
Press the visual button when the square matches the position from N steps ago.
Press the audio button when the current letter matches the one from N steps ago.
Confirm both buttons if visual and audio cues match on the same turn.
Keep accuracy high to increase N, and expect N to decrease after too many errors for a gentler challenge.
Adjust speed and session length, choose practice modes, and review detailed stats after each run to improve.
