Dual-N Back is a mental game designed to challenge your working memory using two types of cues: visual and auditory.
In each session, a 3x3 grid is displayed to players. During each trial, a specific square in the grid lights up while an alphabetic letter is simultaneously played. The player's objective is to determine if the same square and/or sound appeared exactly N rounds prior. The concept of the game was first introduced by Jaeggi et al. in a 2008 PNAS study.

This project owes its existence to Brain Workshop. Down the line, it'd be nice to incorporate more of Brain Workshop's features.

- Trials per session are determined by: Base Trials + Trial Factor^{Trial Exponent}
- Raise threshold is the percent score required to advance a n-back level
- Lower threshold is the percent score resulting in a level reduction
- You can choose to use thresholds with auto mode or manually set your level in manual mode
- Chance of guaranteed match is how likely the game produces a definite position or audio match
