Read full description

The board is populated by viruses of three colors: red, yellow, and blue. In a manner and style considered similar to Tetris, the player manipulates each capsule as it falls, moving it left or right and rotating it such that it is positioned alongside the viruses and any existing capsules. When four or more capsule halves or viruses of matching color are aligned in vertical or horizontal configurations, they are removed from play. The main objective is to complete levels, which is accomplished by eliminating all viruses from the playing field. A game over occurs if capsules fill up the playing field in a way that obstructs the bottle's narrow neck. Players can select the degree of starting difficulty any time a new game is started. The initial level chosen is a value between zero and twenty that determines the number of viruses to clear, and the three game speed options change how fast the capsules fall in the bottle. The player's score is based solely on the elimination of viruses, not on the time taken to complete the level or the number of capsules used. If players complete the highest difficulty level, they can continue playing to accumulate a higher score, but the number of viruses to clear remains the same. Additional points are awarded when multiple viruses are eliminated at once, but no additional points are awarded for initiating chain reactions, in which the elimination of one set of objects triggers the elimination of another set. The game speed is also a factor in how the game calculates scoring; higher speed levels yield more points.

Reimagination and a remake of the immortal classic. Arrange the falling pieces to fill up and clear the lines. Clear as many lines as possible to advance through levels or complete various objectives. This game is inspired by the four brick falling blocks games. But instead of easy four brick pieces, where the name Tetra comes from, this game uses five bricks pieces, thus the name Penta. Of course, you are not limited to either set of pieces. Play any combination you would like and consider more fun. Fun question: Do you see the black dots when you are looking at the game title screen? Do you think they are there? Features: - Play an endless game or complete objectives. - Play individual levels or progress through the campaign. - Smooth and customizable controls. - Various difficulty levels. Controls: The controls were designed to make the gameplay smooth and enjoyable. Below are the few highlights that make this game stand out. - Tap with the second finger or swipe down to drop the piece. Of course, you can use the "Drop" buttons too. - Swipe up to stash the piece and use it later in the game. This allows for more strategic play.
