🧠 Memory Technique
Group these words into clusters of 5 and learn one cluster per day. After a week, test yourself on all 35 — you will retain 80%+ using spaced repetition. Review any forgotten words the following day.
The most effective Scrabble study habit is short, daily sessions rather than long weekly marathons. Five minutes of focused word review every day builds permanent memory faster than an hour once a week.
Advanced Rack Management
🏆 Rack Leave Principle
Elite players evaluate every word not just by its score but by what it leaves on the rack. A good leave: 3-4 consonants + 2-3 vowels, retains S/E/R/T, avoids duplicates.
✓ Good Leave
One high-value tile (J/X/Z) + common letters
✗ Bad Leave
Q without U + multiple low-frequency consonants
