Assembloids 2600

Assembloids 2600 is a fast paced reaction puzzler for the Atari 2600. The goal is to complete figures consisting of four colored pieces. The more uniform the color of a finished figure, the more points you score. But during all that the timer bar decreases faster and faster…
This game was realized in 4 KB to stay true to the original spirit of the early days.

  • The playfield consists of 5 windows, arranged in a plus shape. Parts of creatures in different colours appear in the central one, and then have to be moved to one of the four other windows using the joystick.
  • If a window already has the space of that part occupied the player will lose a life. A life is also lost if the player takes too long to move the part.
  • When a full creature is assembled the player is awarded points. The more uniformly coloured the creature is the higher the point gain. If the player manages to clear all the windows an extra life is awarded.
  • The game gets faster as it goes on, losing a life will slow it down a bit, but upon doing well again it goes back to getting faster pretty quick. There are a number of difficulty settings available, which have an impact on how fast the game gets and how quickly the speed picks up.
