The objective of KBreakOut is to destroy as many bricks as possible without losing the ball.The player is presented with a game field containing a number of bricks. A ball travels across the screen, bouncing off the top and side walls. When a brick is hit, the ball bounces away and the brick is destroyed. The player loses a life when the ball touches the bottom of the field. To prevent this from happening, the player has to use a movable bar to bounce the ball upward, situated at the bottom of the window. The purpose of the game is to progress through the levels destroying all bricks present in each, and trying to get a highscore.

Blinken is based on an electronic game released in 1978, which challenges players to remember sequences of increasing length. On the face of the device, there are 4 different color buttons, each one with their own distinctive sound. These buttons light up randomly, creating the sequence that the player must then recall. If the player is successful in remembering the sequence of lights in the correct order, they advance to the next stage, where an identical sequence with one extra step is presented. If they are incorrect, the game is lost, and the player must start again from the beginning. The goal is to get a high score - each step in the sequence is worth one point, so correct entry of a sequence of 8 lights is worth 8 points on the high score table.
