Spark

What it is

Spark is an aiming and timing game for the browser. There is a core in the middle of the screen, and bodies circle around it on orbits of different sizes. When you tap, a ring leaves the center: every body it reaches lights up and sends out its own ring from wherever it is at that moment, so the reaction chains on.

Each round asks you to light a certain number of bodies before time runs out, and everything depends on picking the right instant, when the orbits line up. Clearing a round is one point, and lighting every body is one more. If you miss the target or time runs out, the run ends. Rounds get more demanding as you go, and one tap restarts the run at once.

With a finger or the mouse

With a finger or the mouse: a single tap launches the spark. The first touch starts the run.

With the keyboard

With the keyboard: the space bar launches the spark. Escape or the P key pauses the game.

Daily challenge

Pick “Daily challenge” on the start screen or after a run. On that day everyone plays the same rounds, and your best score for today is saved separately on your own device. Today’s challenge is the same for everyone on each difficulty, and each one keeps its own best score.

Difficulty

You can play Normal, Hard or Extreme. On the last two the rounds start with more bodies, shorter rings and less time. Each keeps its own best score.
