From the rules:
Junior SCRABBLE® Cards allow you to play two fun card games, based on the Junior SCRABBLE® game from Spear's Games. 'Words and Pictures' is a simple matching game for children aged 5 to 7, and 'Rainbow SCRABBLE®', for children Ages 7 - 10 is based on the classic SCRABBLE® game, with a simplified scoring system. Both games help children with their reading and word formation skills, and introduce them to the world of SCRABBLE®
Words and Pictures
The aim of the game is to collect the most Picture cards. Picture cards are won by placing the last letter of the word on the card.
Rainbow Scrabble
The aim of the game is to score the most points by forming words in a crossword fashion. Players make words by using the Letter cards, which have the same arrangement of letters as in Junior Scrabble.
