About this game

Rack Master helps you master every short word on your Scrabble rack.

HOW TO PLAY
• See a 2- or 3-letter string on Scrabble-style tiles
• Tap YES if it’s a real dictionary word, or NO if it was invented
• Get instant feedback — real words show a short definition

MODES
• Quickplay — endless practice; stop anytime to save a session
• Daily Challenge — one date-seeded set per day so you cover the dictionary over a cycle
• History — review accuracy, duration, and trends
• Reference — offline A–Z short-word dictionary with definitions
• Help — illustrated guide to the app

SETTINGS
• Choose optional word types (plurals, obvious words, Greek letters, letter names)
• Optionally include 2-letter words
• Optional daily reminder for the Daily Challenge

Works offline after install — word lists are bundled in the app.
