Big Twin (1995, Arcade)

Big Twin is a puzzle game developed by Game Over and published by Italian company Playmark. It was only released in the arcades.

Big Twin is a puzzle game with some erotic content. When you play in single mode, each stage an image of a naked woman will be revealed while you play. The image is displayed in the area for the second player in 2 player vs. mode.
The game is about stacking balls. If you have at least three balls of the same type in a single row, either horizontally, vertically or diagonally, they will disappear. Balls will drop from above one at a time. You control cursor, and by clicking on the ball and holding fire, you grab the ball. You can freely move the ball around. If another ball is on top the one you are holding, you cannot lift it upwards any more. You can also grab balls from the stacks to place them somewhere else.
Each stage has a fixed number of balls which will drop. Once all balls have dropped and you didn't go game over (i.e. one stack is above the threshhold at the upper part of the screen), you win the stage. By this time, the image is also fully revealed. If there are still balls on the playfield, you get points subtracted for every one of them. Some stages are more like bonus stages and are more similar to Nazo Puyo. You remove one out of several blocks. Each block holds back a different ball which will then fall down and will make more or less many other balls disappear. The goal is to choose the one that yields the most points.
Like in many similar games, the number of different types of ball increases over time. Also, sometimes a box "filled" two balls will drop. It cannot be turned around, and it cannot be moved once it is placed. Each side of it counts as one ball. There are also bombs, which will remove all balls of the types adjacent to it, a time power-up which will make the balls fall more slowly, an "X2" power-up which removed ball around it, and a red creature which will devour the stack it drops on after a few seconds.
