Hasbro Last Out You Lose is a single- or multiplayer puzzle game where players take turns turning off lights on a grid. The player who turns off the last light loses. The game has three different modes of play:

• Last Out: Players can select any number of consecutive lights in a single vertical row, but must select lights from one end of the row.
• Take 3: Players can select 1, 2, or 3 lights in a single vertical row, from either end.
• Pick 3: Players can select 1, 2, or 3 lights anywhere on the board, even from the middle of a row.

The game includes 48 pre-programmed puzzles and hundreds of random puzzles, providing a challenge for players of all skill levels. It also has a "help" feature that can provide hints for the first move of each puzzle.
