Cubes
Lift a Cube cube list and weight guide: the kilogram curve from the starter Wood Cube to the final block, with the Strength gate behind each one.
Introduction
Every cube in Lift a Cube is a discrete challenge with a weight in kilograms and an implicit Strength gate. Heavier cubes sit farther along the map and pay more once lifted, so the cube list doubles as a progression checklist. This page tracks the weight curve from the community-observed starter Wood Cube upward, explains what each band of weight demands from your Strength, and shows how distance and difficulty rise together. Exact final weights are not officially published, so we describe bands and gating behaviour rather than inventing precise numbers, and we mark the Wood Cube as a community observation. Use the curve to decide when to stop training and walk forward, and when to turn around and raise Strength instead.
Cube Weight Bands
| Cube | Weight Band | Strength Gate | Notes |
|---|---|---|---|
| Wood Cube | Light | Very low | Community-observed starter block |
| Light metal cube | Light to mid | Low | First real step up in weight |
| Diamond-plate cube | Mid | Medium | Steel block shown in official art |
| Heavy steel cube | Heavy | High | Large jump in the kilogram requirement |
| Final cube | Heaviest | Endgame | Waits at the end of the map |

Core Mechanics
Cube progression works by comparison: the kilogram rating on screen tells you exactly how much Strength you still need. When you approach a cube and it will not move, the game is telling you that your current Strength sits below its gate, so the correct response is to return to training rather than to walk further. Each band of weight sits a little farther from spawn, so travel and Strength rise together and the map itself becomes the difficulty slider. Because heavier cubes pay more, clearing a new band is almost always better than farming an old one for hours. The on-screen kilogram counter is also the most honest measure of how far your build has come.
Advantages
A clear cube list turns a vague grind into a checklist. You always know which block you are working toward, how much heavier it is than the last one, and whether your current Strength is close enough to attempt it. That makes training decisions obvious: if the next cube is far out of reach, invest in arms and materials first, but if it is close, a short training session may be enough. Because each cube sits farther along the map, the list doubles as a route planner for exploration. We flag community-observed weights clearly, so you know which numbers to trust, and the list also prevents the classic mistake of assuming a wall is a bug when it is simply a Strength gate.
Challenges
The exact weight of every cube is not officially documented, and the final block's kilogram rating has only been shown in marketing screenshots, so those numbers should not be treated as a confirmed cap. Community-observed values can also change if the developer rebalances the weight curve in a patch. Because a cube that will not move gives no explicit error message, new players sometimes assume the game is broken rather than under-tuned, so we explain the gating behaviour plainly. Distances between cubes are estimates rather than published coordinates, which makes every route description on this page approximate guidance instead of a precise map.

Quick Tips
Use the kilogram readout as your to-do list. The on-screen weight tells you exactly how far your Strength has come and how much more you need, so screenshot the number when a cube stops moving and compare it again after your next upgrade session to measure real progress. Weigh each new band against your current Strength before committing to a long walk.
Never walk past a cube you cannot lift. Distance is gated by Strength, not by exploration, so pushing outward early only adds travel time to your session. If the block in front of you will not move, the map is telling you to train rather than to keep walking toward the horizon.
Treat the final cube as a long-term target, not a mid-game goal. The weight curve steepens toward the end of the map, so plan several upgrade cycles of arms and materials before expecting to budge it, and measure your progress against the previous cube instead of the final one. Re-test the cube after a material roll, because a multiplier can close the gap quickly.
