Spark Drop

Spark Drop is a free browser physics puzzle about one small decision made at exactly the right moment. A spark hangs from a rope, a lantern waits below, and the only thing between them is when you cut. Swipe across the rope, or tap it, and gravity takes over — but the spark keeps whatever swing it already had, so a cut half a second earlier lands somewhere completely different. Thirty rooms are built around that single idea and then keep finding new things to do with it.

Cutting is the first of three verbs and the other two arrive while you are playing rather than in a tutorial screen. At level eight you get Puff: one shove of air, aimed by tapping where you want to push from, which turns a swing that falls short into one that reaches. At level sixteen you get Pin, which hooks a fresh rope from the spark to a marked anchor. Pin is the one that changes the shape of the game, because it lets you build a second pendulum in mid-flight and reach places the original rope could never swing to.

The rooms teach through their parts rather than through text. A sliding anchor moves the top of your rope while you are deciding. An elastic rope stretches and fires the spark further than a normal one. A fraying rope snaps on its own after a couple of seconds, so waiting for the perfect swing is itself a risk. Balloons pull upward instead of down and turn the whole room upside down in your head. Fans push you sideways while you pass through them, teleporters keep your heading, and bouncers give the speed back instead of eating it.

The hazards are as readable as the tools. Spikes and saw blades reset the room instantly, and the saws travel along a visible track so the danger is a timing problem rather than a surprise. Magnets pull the spark toward them with a force that grows as you get closer, which makes a near miss much worse than a wide one. Nothing kills you off-screen and nothing is hidden — if you lost the spark, you can point at the frame where it went wrong.

Six one-off nights punctuate the run and each one changes a rule instead of a number. A blackout leaves only the spark and the lantern glowing. Frozen ropes barely swing, so momentum has to come from somewhere else. A one-cut night gives you a single snip. The depths halve gravity and stretch every arc. A storm pushes everything sideways for a whole room. Dawn pays triple for every mote you collect. Each happens once, which is exactly what makes it stick.

One to three motes sit in every room and they are optional, which is the point — the fast line and the greedy line are usually different. Collecting every mote in a room earns three stars and more coins, and coins buy spare puffs in the workshop for the rooms that beat you. The Level button opens a map of all thirty rooms with the stars you earned in each, so a room you rushed is one tap away when you want a perfect run.

It plays with one thumb on a phone and with a mouse on a desktop, in portrait, and every room fits on the screen at once so nothing important is ever off-camera. If you like Spark Drop, try Mini Putt or Gearlight next.

Swipe across a rope or tap it to cut it — the spark swings free and gravity does the rest. Collect the green motes on the way down and land in the lantern. From level 8 the Puff button spends one shove of air: press it, then tap where you want to push from. From level 16 the Pin button hooks a fresh rope from the spark to a marked anchor, which lets you swing somewhere the first rope could never reach.

Spikes and saw blades reset the room, bouncers keep your speed, teleporters keep your heading, and a fraying rope snaps on its own if you wait too long. The Level button opens the room map with your stars, so you can go back for a perfect drop.
