100 passengers represented as smileys of different colors and moods are waiting in a queue to board the train. Clear combinations of at least three repeating colors or moods to lead the passengers through the carriage door. You will progress to the next level as soon as there is no one left above the laser line. One smiley is added to the queue after a combination is cleared. Every combination grants you bonus points. Longer combinations grant more bonus points. The amount of collected points doubles if the combination is both of the same color and the same mood. Some combinations may trigger the adjacent smileys to form new combinations - you will be awarded a squared sum of points for these. Three additional passengers add to the queue in every consecutive level. The amount of points awarded for every passenger increases as well. Five levels constitute a stage. New colors and moods are introduced in every new stage. The game is over when no more space to accomodate new passangers is available or there are no passengers in the queue.
