Anchor one face
Imagine the question-mark face fixed like a tabletop. Fold each connected neighbor upward around its shared edge, tracing one face at a time instead of rotating everything at once.
Fold all 11 valid cube nets mentally and identify opposite face patterns across 120 progressive levels, daily challenges, sound, hints, and account-free friend challenges.
Study a two-dimensional net, fold it mentally along shared edges, and identify the pattern opposite the marked face.
Level 65 / 120
Marked face: Triangle
Which pattern will be opposite the marked face after folding?
Imagine the question-mark face fixed like a tabletop. Fold each connected neighbor upward around its shared edge, tracing one face at a time instead of rotating everything at once.
Opposite faces are not necessarily farthest apart on the flat net, but they cannot share an edge on the cube. First eliminate every pattern directly connected to the marked face.
Crossing one fold rotates a face by 90 degrees. Trace the connected faces one edge at a time; this is more reliable than judging their up-and-down positions on paper.
Rotating or mirroring the whole net changes its appearance but not its connections. Master levels test whether you can preserve spatial adjacency while ignoring the page direction.
Study the flat net of six squares, anchor the face marked with a question mark, and mentally fold the connected faces along their shared edges. Then choose the pattern that ends up exactly opposite the marked face.
Yes. The puzzle set uses all 11 distinct valid cube nets. The engine also verifies that folding produces six unique face normals, preventing overlapping or invalid questions.
There are 120 levels across Starter, Explorer, Challenge, and Master stages. Early levels use familiar nets and three choices; later levels add all net types, six choices, rotations, and mirrored layouts.
The current date creates a fixed level and pattern arrangement. Everyone receives the same puzzle on a given day, it changes automatically the next day, and no account is required.
First eliminate every face sharing an edge with the marked face, because adjacent faces cannot be opposite. Then hold the marked face still and rotate connected faces 90 degrees one fold at a time.
Yes. A wrong choice adds one error but does not end the level. Remove One can eliminate a distractor if you need help before trying again.
No. After solving a level, Invite Challenge opens the header share dialog with a URL containing the puzzle seed, time, and error count. A friend can replay the identical puzzle and compare results.
It exercises mental rotation, two-dimensional to three-dimensional mapping, spatial adjacency, and working memory. Performance also depends on device and familiarity, so it is not a standalone ability assessment.
