Black Holes

Timing's everything when a wall piece has to crash into a wandering block before it slips away.

I'll be honest—my first run of Black Holes made me question if I'd ever used a mouse before. You drag a wall piece around the screen and your entire mission is to make it collide with a block that's happily bouncing, drifting, or sprinting along its own path. The instructions are one line: move the wall and meet the moving block. That's it. No power-ups, no timers, no story. Just you, a dark shape, and a target with a mind of its own. What kept me coming back is the weird satisfaction of reading the block's next move before it happens. The block doesn't telegraph much—it might coast straight, then juke left, then speed up just as you commit. I had a run where I pre-aimed for a spot I was sure it would cross, and it did, but a split second after my wall had already passed. Missed by a hair. That's the game in a nutshell: prediction and precision, not reflexes. On touch screens, I found it a little easier because your finger can glide the wall while you keep an eye on the whole field; with a mouse, you sometimes lose the block under your cursor. The black hole aesthetic is mostly a vibe—dark circles, minimal contrast—but it makes the moving block pop. For a free browser game, it's lean, clean, and quietly addictive. You'll tell yourself "one more try" after every near miss. Then you'll look up and twenty minutes are gone.

Move the wall piece using mouse/hand and meet the moving block.

Lead the moving block slightly; don't chase it from behind. Use small mouse nudges instead of wide drags for better control. Wait for the block to slow or change direction before committing. On touch screens, keep your finger slightly above the wall piece so you can see the block. Aim for where the block will be, not where it is right now. Restart early if you get out of position—some rounds are easier to reset.
