Voxel
Hold a 3D structure in your mind's eye
Voxel trains 3D spatial memory: a structure of cubes rotates in front of you — memorise where each one sits, plus its colour and symbol — then rebuild it from memory on an empty 3D grid.
How to play
- Study phase: a 3D shape auto-rotates — memorise each cube's position, colour and symbol.
- Build phase: place cubes on the grid to recreate it from memory.
- Pick colours and symbols from the bottom pickers before placing.
- Drag to rotate the camera; remove mode fixes any misplaced cubes.
