Number Scrabble

Number Scrabble (also known as Pick15[1][2][3] or 3 to 15[4]) is a mathematical game where players take turns to select numbers from 1 to 9 without repeating any numbers previously used, and the first player with a sum of exactly 15 using any three of their number selections wins the game.

Each player takes turns picking a number from the list.

If a player has picked three numbers that add up to 15, that player wins the game.

[5][6][7] However, if all the numbers are used and no player gets exactly 15, the game is a draw.

[5][6] The game is identical to tic-tac-toe, as can be seen by reference to a 3x3 magic square: if a player has selected three numbers which can be found in a line on a magic square, they will add up to 15.
