Collins Scrabble

The official 2019 word list to CHECK, SOLVE and TRAIN your way to SCRABBLE™ success. Endorsed by Mattel and adopted by WESPA, the World English-Language Scrabble Players' Association for use in WESPA tournaments.
Designed for all SCRABBLE™ players, whether you're on the board, online, or training for a tournament.
Ad-free, portable access to words, definitions and scores for all 279,496 valid words, this app has 3 main functions:
CHECK if your word is a valid SCRABBLE™ word and solve all those arguments when playing
SOLVE by entering your rack tiles and view all possible word solutions. A cheeky cheat while playing, if your conscience allows it! And helps you to practice with difficult combinations of letters.
TRAIN against the clock with random racks to improve your game play with your virtual trainer. WARNING: this is highly addictive!
If playing with family and friends you can switch to a smaller word list by looking under Settings and exclude terms which may cause offence.
