Game is played on a 6x6 board. On start game randomly spawns 4 bubbles with random colors on random locations. Every move you can move any bubble to any of the fields to which there exists a path through empty fields. If you manage to mach bubbles with same color in a line with minimum length of 4 you will terminate that line and the bubbles making that line will get destroyed. If you make a move without line termination 3 new bubbles with random colors will spawn on random locations. Game ends when you fill out the entire board with bubbles making the game not able to spawn 3 more bubbles. Your score is based upon how many line terminations you done, how big the terminated lines are and how fast you were at terminating them.
