Trace

One puzzle. Every day.
DAILY

Connect all five dots, then check your trace.

Trace playing field The ball moves steadily and reflects off the walls. Each marked point is a snapshot taken one second apart. Select the five snapshots in chronological order.

How to play

Find the order of five snapshots in 3 attempts.

  1. Each dot is the same ball, one second apart. It moves at a steady speed and bounces off the walls.
  2. Draw through the dots in time order, or tap them one by one. Either direction counts. You only choose the order; the game checks the wall bounces.
  3. Connect all five, then press Check trace. Undo removes the last dot. Clear starts a fresh trace.
