Play to set a score, then submit it to the board.
How to play
- A 3D shape is hidden somewhere inside the cube grid — you cannot see it directly.
- Query a slice along any axis and layer to reveal that cross-section as a flat silhouette.
- Use the silhouettes you have gathered to build your best guess of the full 3D shape, layer by layer.
- Submit your guess to check it against the hidden shape — an exact match wins, and giving up early still scores partial credit for how close you got.
Strategy & tips
- Slice along different axes early — an X-axis slice and a Y-axis slice of the same layer reveal different information about the same region.
- A silhouette rules out every cell that is empty in it, not just confirms the cells that are filled — use the negative space too.
- You have a limited number of slices, so prioritize the layers most likely to disambiguate between the shapes you are still considering.
- Partial credit rewards a close guess, so if you run low on slices, submit your best reconstruction rather than guessing wildly.
FAQ
How do you play Strata?
Query slices along the X, Y, or Z axis to reveal flat silhouettes of the hidden 3D shape, then paint your guess onto the voxel grid layer by layer and submit it.
What happens if I run out of slices?
You can still submit your best guess or give up — either way you score partial credit based on how close your guess is to the actual hidden shape.
Can I play a fresh puzzle every day?
Yes — Daily mode gives everyone the same seeded shape each day, with a streak counter for playing on consecutive days. Practice mode gives you a fresh random shape at any difficulty.
