VoxelForge
Turn 3-D shapes in your head and build them block by block (ages 9-14). Spot the true rotation - turned, not flipped - and stack a shape one flat layer at a time. Meet the crew who each ARE one spatial move: Turnwick turns a shape without changing it, Twinn is the mirror you can never spin to match, Roundle keeps all 24 turns of one shape, Layla builds floor by floor, Cubbin is the single block, and Fitwell checks every cube against the goal. On-device, no accounts, no ads.
#6d28d9 Distributed-narrative cast
Meet the cast
VoxelForge is a crew of block-builders who each embody ONE spatial-reasoning move - the cast IS the curriculum. Learning to turn shapes in your head is learning what each of them does: Turnwick turns a shape and it stays the same shape, Twinn is the mirror-double you can never spin onto the original (a flip is not a turn), Roundle collects all 24 turns of one shape into a single family, Layla builds a tall shape one flat layer at a time, Cubbin is the single cube every build is made of, and Fitwell checks a build against the goal cube-for-cube.
Turnwick
Embodies rotation - turns a voxel shape through space so it lands in a new pose but stays the SAME shape (turn it, don't change it)
Read chapter →
Twinn
Embodies the mirror image (chirality) - the flipped look-alike that no rotation can ever match, like your left hand and your right (a flip is not a turn)
Read chapter →
Roundle
Embodies the rotation orbit - keeps all 24 turns of one shape as a single family; two shapes are the same if some turn lands one exactly onto the other
Read chapter →
Layla
Embodies layers (slices) - builds a 3-D shape one flat horizontal layer at a time, floor to roof, so a tall build is never scary
Read chapter →
Cubbin
Embodies the voxel - the single unit cube placed at exactly one spot; every giant build is just single cubes, each in its right place
Read chapter →
Fitwell
Embodies the match check - compares a build to the goal cube-for-cube and says 'matches' only when every block lands exactly (looks-close and matches are two different words)
