Lift a Cube Tools
Time-to-gate math and session checklists — no rebirth calculator needed.
Lift a Cube is a numbers game wearing a joke title. The cube does not care how determined you look. It cares whether Strength is at the gate. This hub is the pocket calculator for that sentence. It does not replace how to train or the walkthrough. It turns those pages into time and a session order.
Two tools:
- Strength calculator — hours and days to 1.3 billion at different Strength-per-second rates
- Training planner — a repeatable session: Train, bubbles, legal lift, upgrade, leftover rolls, walk or stand
There is no rebirth planner because there is no rebirth. If a third-party sheet asks for prestige count, it was written for a different simulator. Close it. Use these two pages.
Why a calculator exists here
Default gain is one Strength per push-up before materials and training-speed upgrades. Sportskeeda documents that baseline and the 1.3 billion last-cube gate. At one Strength per second you would need on the order of fifteen thousand days. That is not a motivational poster. It is why arm materials and map upgrades are not optional flavor. They are the only way the gate is human.
The calculator page lists round rates (1, 10, 100, 1,000, 10,000, 100,000 Strength per second) so you can sandwich your live number without pretending we scraped a private API. Read your Strength-per-rep in-game, multiply by how many push-ups you complete in ten seconds, and pick the nearest row.
Why a planner exists here
New players AFK Train with no lift, or mash the heaviest cube with no Train. Both waste the same hour. The planner is a five-block loop you can run while a video plays:
- Start Train (1)
- Click multiplier bubbles
- Lift the heaviest cube you can actually finish
- Buy the local upgrade before the chest
- Roll leftover Cash, equip if better, walk or keep standing
That order matches Getting Started and the spend advice on the upgrades tier list. The planner just makes it copyable.
What these tools will not do
They will not inject a script. They will not guess a material name Freaky Strong! has not posted. They will not tell you a Robux pack is required. They will not estimate a rebirth because the live loop has none. If you want automation talk, that is the scripts hub — and even there, key 1 already idles training.
Use the calculator when you are staring at a cube labeled in the millions and wondering whether to stand still for an hour. Use the planner when you have twenty minutes and keep forgetting to spend Cash. Then go back to the map.

Frequently Asked Questions
Quick answers for training, cubes, and arm rolls.
Do I need a rebirth calculator for Lift a Cube?
No. There is no rebirth. Use the strength calculator for time-to-gate instead.
How do I measure Strength per second?
Read Strength gained over ten seconds of Train, then divide. The strength stats page explains the baseline of one Strength per push-up.
What if my rate is between two table rows?
Use the slower row so you overestimate time. Then buy a training upgrade from the upgrades tier list.
Is the planner an auto farm?
No. It is a manual session order. Built-in Train already AFKs push-ups. See the training planner and the scripts hub.
