This is the Scrabble Original board game by Mattel.
It is a classic word game where players form interlocking words, crossword-style, on a playing board using letter tiles.
The game can be played by 2-4 players.
Points are earned based on the commonality of the letters used, with certain board spaces offering bonus points.
The set typically includes 100 letter tiles, a playing board, four racks, a cotton tile bag, and rules sheet.
