This Mac puzzle game is free and open source.
One unique feature of XSwing Plus is that five balls of the same color in a column will shrink to one heavy ball. As you progress in the game and reach every 50 balls, a new color will be added to the mix, increasing the difficulty level. Be careful not to stack more than eight balls, though.
The game is easy to play, with simple key commands to maneuver the crane, drop balls, start a new game, change the ball set, disable particle effects or exit the game. It even has a toggle for fullscreen and an experimental option to change the game size.
Overall, XSwing Plus is a fun, challenging, and free game to play casually during your breaks. Its unique ball-disbanding strategy will keep you engaged and wanting more.
