Community is TraceBlazer's user-generated puzzle library — every layout in it was built by another player with the in-browser puzzle creator, not by the Samprino Tech team. It turns One-Stroke Puzzle from a fixed set of levels into something that keeps growing as long as players keep designing.
Building a puzzle: the creator won't let you publish a broken one
The creator is a simple canvas editor with four tools — place a node, draw an edge between two nodes, move a node, or delete one. You're literally drawing the graph your puzzle will be built from, the same nodes-and-edges structure the Learn — Euler Paths guide explains.
That matters here for a practical reason: before you can publish, the creator checks your design against the same two conditions that decide whether any Euler path exists — the graph has to be fully connected (every node reachable from every other node), and it can only have zero or exactly two nodes with an odd number of edges. Design something that fails either check, and it won't go live. You can't accidentally publish an unsolvable puzzle for someone else to get stuck on.
Naming, difficulty, and category
Once your graph passes validation, a second step collects the metadata other players will see: a name, an optional description, a self-rated difficulty from 1 to 10, and a category — Geometric, Artistic, Maze, Pattern, or Challenge — plus whether the puzzle is public or kept private. Difficulty is shown to players as a color-coded badge (green for easy, orange for medium, red for hard) on the puzzle detail page before they commit to trying it.
Sharing and discovery
Publish a puzzle and you get a short share code, in addition to its normal page — handing someone that code links them straight to your puzzle without them needing to search for it. For puzzles you'd rather have people find organically, the Community browse page lets visitors filter by category and sort by Most Liked, Newest, Most Played, or Easiest First, plus a search box for finding a specific puzzle by name.
Likes, ratings, and stats
Every community puzzle tracks real engagement data: total plays, completions, a like count, and an average star rating from everyone who's solved it. Players can like a puzzle once (it turns into a filled heart) and leave a star rating after solving — both feed directly into the Most Liked sort and the average rating shown on the puzzle's own page, so puzzles that are genuinely well-designed rise to the top over time rather than just the newest ones.
If you publish a puzzle and want to tweak it later, everything you've created lives on your My Puzzles page, where you can jump back into the creator to edit the same layout rather than starting over.
