Decoy Grid: Puzzle

Decoy Grid: Puzzle is a calm, offline grid-placement puzzle. Each level shows a target shape and a tray of puzzle pieces — but some of them are decoys that look almost identical to the real ones. Your job: place the real pieces on the grid to rebuild the target pattern. Decoys can sit anywhere in the empty area, but they must not cover the target. Tap a placed piece to take it back; there's no timer, no step limit, and no fail state — just solve at your own pace. Features · 120 levels generated deterministically by an algorithm (level number = seed), so every puzzle is guaranteed solvable. · 5 difficulty tiers: from 4×4 grids with 1–2 decoys, up to 10×10 grids with 8–9 near-identical decoys and locked cells. · Perfect clear: place every piece, decoys included, for a bonus star. · Two input styles: drag a piece onto the grid, or tap to select then tap to drop. Live preview shows valid/invalid placement. · Optional rotation (where a level allows it) and a toggle to hide the target outline for a harder run. · Fully offline: no account, no sign-up, no network, no ads, no in-app purchases.
