Get all balls to their corresponding color destinations at the same time. Each ball can move with speed ranging from 1 to 10, 1 being the slowest speed, and 10 the fastest (chosen by the player after touching a ball). Simul has 15 levels. At level 1 the player is challenged to get two balls to their destinations at the same time. At level two the task is to get 3 balls, then 4, up to 16. Each level gets harder for the player to determine the approximate distance of each ball to its destination. Understanding that this game can be challenging, we dropped hints all the way until level 10 ... after that level only the most precise eyes can pass. You shall not pass.
