"Pull the Pin" is an engaging and strategic game that tests a player's attention to detail and problem-solving skills in a fun and entertaining manner. Played across multiple levels, each increasing in difficulty, the player's main goal is to release colored balls into a container by carefully removing pins that separate the balls from their target.

To begin, the player is presented with a screen that contains one or multiple containers, colored balls, gray balls and pins in different arrangements. The challenge lies in judging the sequence of pulling the pins. You must carefully strategize the order of pulling the pins to let the colored balls fall into the container while avoiding the gray balls as much as possible. A level is successfully completed when all colored balls have reached the container.

To add to the complexity, sometimes you will also be faced with obstacle blocks as you progress to higher levels, which restrict the movement of the balls and these obstacles must also be tactfully navigated by controlling the pins. Furthermore, some levels also include 'bombs' and they must be tactfully avoided to prevent the colored balls from being obliterated.

The charm of "Pull the Pin" lies in its simplicity yet progressive challenge. There are no timers, allowing players to take their time in strategizing their moves, making it a relaxing yet mentally stimulating game. In order to master this game, it is crucial to think ahead and anticipate the effects of each action, similar to a game of chess.

While the game initially appears simplistic, becoming victorious requires thought, planning, strategy, and a good understanding of the game's mechanics. The real fun and challenge of "Pull the Pin" come from working out these mechanics, making smart moves, and seeing your strategy succeed as you complete each level. With its increasingly complex levels and engaging gameplay, it can easily become a game that keeps you hooked for hours.
