Shadow Grid
About Shadow Grid: Spatial Memory Puzzle Across Four Grid Sizes
Shadow Grid is a spatial memory puzzle game built around one deceptively simple challenge — watch a grid flash a sequence, hold it in memory, and tap it back correctly. Starting on a 3×3 grid with short 3-cell sequences, the game physically expands through 4×4, 5×5, and 6×6 grids as rounds are cleared, while sequences grow longer and more complex. What begins as pure position memory evolves into multi-attribute recall: cells gain color, shapes appear inside them, and noise decoys flash to throw you off.
The difficulty never jumps — it builds through 1,212 carefully designed levels, introducing one new mechanic at a time. A single continuous difficulty parameter unlocks color, shape, noise decoys, and a color-shape picker progressively. Grid expansion animations signal every new size before the round begins. The design is clean and minimal, built entirely from drawn shapes with no external assets required, and runs on any modern mobile or desktop browser with instant load and no download needed.
How to Play Shadow Grid: Watch, Recall, and Advance
Shadow Grid tests one skill — how well you are able to watch a sequence, hold it in memory, and tap it back correctly. The grid gets bigger, the sequences get longer, and every level adds a new layer of complexity.
Three Phases Per Round
- WATCH: The grid flashes a sequence. Cells light up one by one — study them carefully.
- RECALL: The grid goes dark. Tap the cells you saw, in any order.
- LOCK: Tap LOCK to submit your answer. All cells are checked at once.
Lives and Regression
- Each session starts with 3 lives. Get a round wrong and lose a life; lose all three and the session ends.
- Your checkpoint saves after every correct answer.
- If a session is lost, the checkpoint moves back based on how far you fell — the further you dropped, the more you regress.
- Revive cancels the regression entirely and restores your score.
Progress and Streaks
- Your checkpoint, lifetime score, best streak, and daily streak all persist across sessions.
- Each time you return, you pick up exactly where you left off.
Tips
- Tapping order does not matter — just get the right cells selected.
- In harder levels, color and shape matter too, not just position.
- Use the ↩ Replay button to rewatch the sequence if you have tokens.
