Speedcubing

For the grown-up beside a child who loves speedcubing.

The child's own door is Speedcubing on Spark & Anvil.

There is no Whetstone tool or course for speedcubing yet, so this page is the sideline card and your child's ladder.

The sideline card

Three numbers to notice

  1. Inspection: just under 15 seconds to look at the scrambled cube before the solve starts.
  2. An average of five: the fastest and slowest solves are dropped and the middle three are averaged.
  3. A 3×3 cube can be in 43,252,003,274,489,856,000 positions.

On the way home, ask: “Which solve today felt smoothest, and what were your hands doing?”

Ask because you are curious, and let any answer stand. Print this page for a half-page card.

Numbers checked against: World Cube Association Regulations (A3a1 inspection; 9f8 average of five); Rokicki, Kociemba, Davidson and Dethridge: God’s Number is 20 (the count of positions)
