Infer 3D block models from front and top projections across 120 progressive levels, with daily puzzles, hints, sound, and account-free friend challenges.
Compare the front height profile and top footprint, then find the only 3D block model that matches both projections.

📘 3D Shadow Match Strategy Guide
1
Read the top view first
The top view tells you which floor cells contain at least one cube. Eliminate any model with an extra or missing occupied cell.
2
Compare the front columns
The front view shows the tallest stack visible in each column. Check that height profile from left to right.
3
Account for hidden cubes
Only the tallest stack survives in a front projection, so shorter cubes behind it may be hidden. Always combine both views.
4
Start with distinctive clues
Find the tallest pillar, corner footprint, or isolated bump first, then verify smaller details. This is faster in Challenge and Master stages.
❓ 3D Shadow Match FAQ
How do you play 3D Shadow Match?
Compare the tallest stack in each front-view column and the occupied cells in the top view, then choose the only 3D block model that matches both projections.
Can two views always determine a unique 3D shape?
Not in unrestricted geometry. This game therefore uses multiple-choice inference: the engine calculates every candidate projection and guarantees that exactly one option matches both supplied views.
How many levels are included?
There are 120 levels across Starter, Explorer, Challenge, and Master stages. Boards grow from 3×3 to 4×4, stacks rise from two to four cubes, and distractors become progressively more similar.
What do the front and top views show?
The top view shows which floor cells contain cubes but not their heights. The front view shows the tallest visible stack in each left-to-right column.
Is the Daily Challenge the same for everyone?
Yes. The current date creates a fixed level and model for that day, so everyone sees the same challenge. It changes the next day and needs no account.
Can I continue after a wrong answer?
Yes. A wrong choice adds one error without ending the level. Remove One can hide a distractor when you need a hint.
Do friend challenges require an account?
No. After solving a level, Invite Challenge opens the header share dialog with a URL containing the puzzle seed, time, and errors. Friends replay the identical puzzle.
What skills does this game practice?
It develops two-dimensional to three-dimensional mapping, spatial visualization, visual working memory, and systematic elimination, making it suitable for early spatial geometry practice.
