Encoding Systems
Create a digit-to-image table (0=hero, 1=candle, 2=swan). Combine images for each chunk and place them in a story. The more sensory detail, the better.
Scheduling Practice
Use 3-1-3 structure: three attempts, short break, three attempts. Stop when accuracy drops below 70%.
Plateau Busting
Change variables—play standing up, switch devices, or add background noise to build robustness.
Action steps
Map palaces
Use familiar locations to store sequences.
Review weekly
Revisit best strategies and adjust.
Recommended games
Turn the idea into a score.
Run one relevant game, note your baseline, then repeat under the same conditions when you want a useful comparison.
