The ladder

Where do
you start?

Most people start around 300 ms. Racers sit near 250. Pro drivers live at 200, and under 180 is Beyond. GridReady ranks every run on the same ladder.

01 · The Daily Grid

One grid.
Everyone.

Every day, every player on Earth gets the exact same five starts. One try, so it counts.

  • Your score is the median of your clean starts, so one lucky tap can't carry it.
  • A jump start costs 100 ms. Fewer than three clean starts is a DNF.
  • A new grid opens every day at 00:00 UTC, numbered like a race calendar.
GridReady home: best reaction 179 ms, level 9, a 12-day streak, and today's Daily Grid ready to start

02 · Friends

Race your
friends.

Standings run on Game Center, so your friends are already there.

  • See where you finished among friends on every Daily Grid, and where you rank in the world.
  • Challenge a friend to beat your grid or your best Lights Out time. Apple tells you the moment someone passes you.
  • Ten achievements, from Formation Lap to Beyond, collected in Apple's Games app.

03 · Progress

Get faster.
Every day.

A 30-day trend, a best for every drill, your top Daily Grids, and a straight answer to "am I faster than last week?"

  • Your reaction trend, drawn against the 200 ms pro line.
  • Levels, streaks and a personal best for every drill.
  • A gentle reminder at 6 pm, only on days you haven't raced.
