BubbFrz VEL is a vertical number-merging mobile game centered on a 5x5 grid. Players swipe up, down, left, or right to push diamond-shaped tiles with the same number to collide and merge, progressively reaching higher values, with the ultimate goal of combining to 2048. The game allows pausing, restarting, or returning to the main menu at any time. Invalid swipes trigger haptic feedback, while merging scores are tallied in real time and the highest record is automatically updated. With limited board space, careful route planning and timing are equally important, making it easy to pick up yet rewarding for repeated high-score challenges.
