Lift a Cube Strength Calculator

Estimate how long your next Strength goal will take. Enter your current Strength and effective training rate, or measure that rate below.

Measure your actual rate

30–60s suggested

Keep the same Arm, Material and boosts for the whole sample. Three rounds give a steadier median.

How to measure your Strength per second

  1. Record the exact Strength shown before training.
  2. Keep the same Arm, Material and temporary boosts.
  3. Train for 30–60 seconds and record the ending Strength.
  4. Repeat at least three times and use the median rate.

These durations are measurement advice, not a verified game mechanic. If the display rounds to K or M, use a longer sample or a more precise readout.

What this calculator assumes

The rate remains constant for the estimate, your setup does not change, and the target is a goal you chose. A measured effective rate already includes whatever boosts were active; do not multiply them in again.

remaining = max(0, target − current)
time = remaining ÷ Strength per second

Weight is not automatically a Strength requirement

The official description says Strength helps you lift cubes faster and that later cubes are heavier. It does not establish a fixed minimum Strength for each cube. This calculator therefore never claims that a target unlocks a particular cube.

Why your estimate can change

Arms, Materials, temporary boosts, rounding, lag, resets and game updates can change the measured rate. Measure again whenever conditions change.
