Best Upgrade Order in Lift a Cube

Priority 1 — Push-up time upgrades (S tier)

Cheapest permanent strength-per-second gain. Buy every tier you can afford the moment you can afford it, in every zone.

Priority 2 — The next arms tier (A tier)

Bigger push-up time cuts than the small upgrades, at a bigger price. Keep your arms within one zone of your current cube; if you can lift the next cube's gate comfortably, bank Cash for the arm instead.

Priority 3 — The next zone's chest roll (A tier)

One roll at a further chest beats several at the closer one: better odds, better multipliers, and the multiplier applies to all future training. Re-rolling the starter chest is the classic Cash trap (C tier).

Priority 4 — Luck upgrades (A tier)

Once a chest's price exceeds your next arm upgrade, luck becomes the better spend: it improves every future roll at that chest. Observed tiers ≈8×, 10× and 20×.

Priority 5 — Movement speed (B tier)

Not a strength stat, but it shortens every walk between cubes, chests and stations — and the cheap tiers cost almost nothing. Buy the cheap ones, skip the expensive ones until endgame.

What not to buy

Re-rolls at the starter chest, expensive movement speed tiers mid-game, and any roll you cannot feel: a multiplier that saves you seconds at your current gate is worse than the arm that saves you minutes at the next one.
