Tile Sudoku — Sudoku you assemble from tiles - Todd - 07.08.2026 Hello, I'm Todd — the same solo developer who posted about Spectradoku here recently. I've been working on another free browser puzzle, Tile Sudoku, and I'd love to share it with you. https://tilesudoku.hitodd.com/ ── What it is ────────────────────────────────────────── TileSudoku is Sudoku you build by placing pieces, not by filling empty cells. Each piece carries a digit and a geometric edge profile. You start with a tray of tiles and must place every tile onto the board so that: Digits — each row, column, and box contains each digit exactly once (standard Sudoku). Edges — neighboring tiles must fit. There are two live variants: Jigsaw — tabs and blanks interlock; thick edges mark the outer frame and box borders, thin dashes mark edges inside a box. Curve — blue curve must form closed loops inside the board; thick/thin borders work the same way. Some harder Jigsaw levels include “?” tiles: you place the shape first, then fill in the digit yourself before the puzzle is complete. In play it feels like packing a jigsaw (or joining curve fragments) while continually checking Sudoku constraints — geometry and digits keep informing each other. ── What makes it different ──────────────────────────── • Not a reskin of classic Sudoku. The primary move is choosing which tile goes where, under joint geometric + digit rules.  • Two distinct edge languages (Jigsaw tabs vs Curve ports) on the same platform.  • Progressive packs: smaller grids to learn the feel, then denser 9×9 Jigsaw with blank tiles.  • Built for phone and desktop — drag or tap-to-place, draft ring for temporary storage, undo, auto-save, bilingual UI (EN/中文).  • Completely free. No signup, no paywall. Opens in any modern browser. ── Try it ────────────────────────────────────────────── https://tilesudoku.hitodd.com/ I'd suggest starting with Jigsaw 6×6 to learn the edge rules, then moving to Jigsaw 9×9 when you want a longer session.
