About Backspace
Backspace is a five-lane endless dodger with a single, brilliant cheat built into it: you can rewind the whole world. Blocks scroll toward your marker and you flick between lanes to thread the gaps, but hold Space and the entire scene runs backward — obstacles retreat, your distance unwinds — then release and play resumes forward from that earlier instant, free to pick a different lane through the wall that just killed you. The catch is that rewind is a draining meter, not a free undo; spent time is never refunded, and a crash only actually ends your run when the meter is empty. So the discipline is hoarding it for gaps you genuinely could not read, and scrubbing back only just far enough to reach the fork you needed. Surviving cleanly without rewinding grows a clutch multiplier, making honest stretches worth far more than scrappy rescued ones, while the world keeps speeding up and demanding you plan two rows ahead. Free in the browser with no sign-up, it saves your best run to beat.
How to play
- Use the arrow keys or A and D — or tap either side of the board — to switch between five lanes.
- Blocks scroll toward your marker; thread the gaps to survive and score.
- Hold Space (or the BACKSPACE button) to scrub the world backward — obstacles retreat and you rewind to an earlier instant.
- Release to resume from that moment and pick a different lane. The rewind meter drains as you scrub, and a crash only ends the run when it is empty.
Strategy & tips
- Rewind is a resource, not a free undo — spent meter is never refunded, so save it for gaps you genuinely cannot read.
- Scrub back just far enough to reach the fork you needed, then release. Over-rewinding burns meter and distance.
- Surviving without rewinding builds your clutch multiplier, so clean stretches are worth far more than scrappy ones.
- Commit to a lane early. Late lane changes at high speed are what fill the block wall in front of you.
- The world speeds up with distance — start planning two rows ahead before you need to.
FAQ
How does rewinding work?
Hold Space and the entire world runs backward — obstacles retreat and your distance unwinds. Release and play resumes forward from that earlier instant, so you can take a different lane.
Does a crash end my run?
Only when the rewind meter is empty. Otherwise a safety net rewinds you automatically so you can fork to a different lane.
What is the clutch multiplier?
It grows while you survive without rewinding and boosts your score. It resets when you scrub back.
