How to play

  • Press Space, tap, or click to arm a round — a start flash fires, then an end flash fires some time later.
  • There is no visible countdown or progress bar between the two flashes — only your internal sense of time.
  • Tap again exactly halfway between the start and end flash. The closer to the true midpoint, the higher the grade.
  • You have three lives — a false start, a miss, or a badly-timed tap costs one. The run ends when you run out.

Strategy & tips

  • The screen stays completely blank between flashes on purpose — resist the urge to count out loud and instead judge the gap by feel.
  • The interval length changes every round, so a fixed rhythm from the last round will not carry over to the next.
  • A streak of good taps in a row builds a growing bonus, so consistency across rounds is worth more than one lucky perfect hit.
  • Tapping too early is treated the same as tapping too late — aim to feel the gap shrink rather than guessing towards either end.

FAQ

How do you play Bisect?

Press Space, tap, or click to start a round. Watch for the start flash, then the end flash, and tap again exactly halfway between the two — there is no visible timer.

Why is there no countdown or progress bar?

The blank screen is the entire point — Bisect tests your internal sense of elapsed time, not your ability to read a clock.

Does the game ever end?

No — Bisect is an endless survival run with three lives. Play continues until you run out.
