The GAME() function
Putting =GAME() into any cell results the text "say what?" in that cell.
Putting =GAME("Froggie") into any cell results the text "Froggie" in that cell. Putting =GAME("Froggie") into any other cell afterward results in the text "oh no, not again!"
Put the =GAME(A2:C4;"TicTacToe") formula into A1 and press ENTER. A version of the Tic-Tac-Toe game is playable.
Put =GAME("StarWars") into any cell and press ENTER. A version of Space Invaders is playable. Although if you try to play it again, the message "oh no, not again" appears. To play again, you must fully close OpenOffice.org.
- This easter egg has been removed since DEV300_m72 (which will become OO.org 3.3). This function now behaves the same as Froggie above.
