Slackball

Slackball is a minimalist Pachinko-style marble game designed to sit in a transparent, borderless window on your desktop. You bet on a marble, launch it through pins and try to land it in a winning slot.

Bets and multipliers

Adjust your wager with the plus and minus buttons, then confirm to receive a randomly assigned x2, x4 or x8 multiplier and activate the winning slots. Higher multipliers leave fewer winning slots, balancing greater rewards against a lower chance of success.

To launch a marble, hold the plunger at the bottom of the screen to charge it, then release. A marble that lands in a lit slot wins a reward. You can reset your marble count to its initial state with Marbles Rewind, and the game tracks your highest score in real time.

Desktop presentation

The game uses minimalist vector visuals and a transparent window that can float in a corner of the screen, stay on top of other windows and remain borderless. It is playable with a mouse.
