A cube timer helps you discover whether your solving is becoming smoother. Cube Guruu currently provides a training timer in its 3D simulator; this guide explains how to use timing productively rather than claiming a standalone competition timer.
Follow the lesson
Scramble fairly
Use a sufficiently mixed puzzle. Record the scramble when you want to review a solve.
Decide your inspection rule
For casual practice choose a consistent inspection window. Official competition procedures are more specific, so consult the current WCA regulations for official attempts.
Start the timer and solve
Keep your timing method consistent across sessions and avoid changing controls between attempts.
Review several results
Look at the median and mean as well as your personal best. A single fast solve can be misleading.
Identify a specific drill
If the cross is slow, work on cross planning; if last layer causes pauses, practise recognition.
The on-site 3D simulator is useful for observing moves, but on-screen mouse controls do not measure physical speedcubing performance in the same way as a stackmat or dedicated timer.
Practise it on a real cube
Keep your physical cube in the same orientation as the instructions. Perform each face turn slowly, stop and check the stickers, then compare with the 3D trainer. Voice lessons can guide screen-based practice; physical cube moves are confirmed by the learner rather than checked by a camera.
How to know you are ready to move on
Repeat the exercise from a fresh starting position and explain what each turn is meant to accomplish. If the result differs from the target, go back to the earliest step you can verify instead of immediately starting over. Use cube notation whenever a move symbol feels unclear.
