Last Line Loses is a very simple game to play. Players take turns removing lines from the game board until there is only 1 line remaining. The player which removes that final line loses the game. There are only 2 simple rules to follow.
1. A player must remove 1 or more lines each turn. 2. A player can only remove lines from 1 row each turn.
To make a move, say something like, "Remove 2 lines from row 3."
The game board has 4 rows. Each row contains a different number of lines. The rows are numbered 1 to 4 and, when a game begins, they start with 3, 5, 7, and 9 lines respectively. The goal is to leave only 1 line remaining on 1 row. The opponent then has no choice but to remove the last line and lose.
You can see the board as you play in the Alexa app. This helps tremendously in visualizing the board.
