Overview
Lose Your Marbles is an action-puzzle game developed and published by SegaSoft for Windows PCs in 1997.
In Lose Your Marbles, players have a 5×15 playfield of marbles that expand outward from the center, with players able to roll columns up and down or shift the center-most row left and right (the latter of which loop around). The objective of the game is to clear marbles by matching three-or-more marbles of the same color in the center row, with a full five-column match sending additional marbles to the opponent.
Along with a single-player mode against an A.I. opponent, the game includes multiplayer, both local and networked. A demo version of the game, known as Lose your Marbles Lite!, was later included in the Microsoft Plus! 98 software package ( along with Spider Solitaire and a demo of Microsoft Golf: 1998 Edition) that limited the game to the single-player mode.
Along with its inclusion in Plus! 98, the game is known for its tagline in early releases: "Better than Tetris or your money back!" It is unknown whether or not players get a full refund for their disappointment, and the game was later re-released without the tagline.
