Junction — About this game
Junction turns a sliding-block board into a live routing puzzle. The red ball keeps moving while you rearrange track pieces around the empty square. Your goal is to pass every checkpoint, not merely make a neat loop. A ball is lost if it meets an enemy, has nowhere to go or runs out of time. Think ahead about where the next turn leads before moving a useful piece out of its path. Speed-up and limited slowdown help control the pace, but do not replace a connected route. Configuration lets you choose among fifty stages, set the stock of balls and change difficulty. Start slowly and build a route through nearby checkpoints before reaching for a distant one.
