Slotbox

Slotbox is a tap-based arcade app; Bubble Shooter is the only game in the collection that uses a cannon mechanic, aimed upward at a bubble grid from a fixed position at the screen bottom. The cannon fires one bubble at a time. The color of the next bubble is shown in the queue so you can plan your shot before it's loaded. The queue rotates through available colors. You aim by moving left or right to position the cannon before firing, the angle changes the trajectory, and the preview line updates in real time as you adjust position. Each bubble sticks on contact with the grid or other bubbles, immediately resolving cluster checks. Same-color matches of three or more are cleared the instant the bubble lands. The cannon mechanic is unique among Slotbox's four games, it's the only one requiring directional aim rather than pure timing. Offline, no login, high scores saved per stage.
