Let the explicit clearance condition define the next billiards choice.
The target is unusually specific
Black Hole Billiard describes a single-player arcade pool task: put all red balls into the black hole to clear a level. Read that condition before assuming a standard competitive billiards ruleset. The table may resemble familiar pool, but the objective supplied here concerns a particular set of balls and destination. The source does not establish stripes, solids or a conventional eight-ball finish.
Inspect the remaining group
Before the next action, identify which red balls are still present and where they sit relative to the hole. Consider what an intended contact would change for that remaining group, not only the nearest ball. This is a board-reading question rather than a tested claim about a particular shot. Use the actual game's aiming and power instructions; the control field simply says mouse.
Confirm clearance from the interface
After a ball disappears, check the displayed state before deciding that the level is complete. A ball leaving view and a recorded successful pot are not necessarily the same event. The listing advertises eleven levels but provides no verified table layouts or physics values. This note offers no guaranteed clearance sequence. It helps keep attention on the explicitly named red-ball requirement instead of importing a different pool game's scoring or finishing rules.
