Fill and Flow
Read full descriptionHide full description
Balls follow paths you create to fill up the boxes with matching color. Once full, boxes are closed and packed. By moving the boxes around, you can create new paths to free stuck boxes. Frozen boxes are stationary. Fill enough boxes to shatter them. If a box has an arrow, it can only move in specified directions. Boxes with Bombs need to be filled before the countdown reaches zero or you lose! Grey Boxes are stationary, as well, but fillable by blue cue balls. If timer reaches zero, you lose. Use Freeze Time to stop the timer and get ahead. If you get stuck, using Magic Wand will fill a box of your choice and allow new strategies.
