About TraceBlazer

TraceBlazer is a one-stroke puzzle game where you solve graph-based puzzles by drawing a single unbroken path that travels along every edge exactly once. The challenge comes from finding the correct sequence of moves — there is only one stroke allowed, no retracing, and no shortcuts.

The game is inspired by the famous Königsberg Bridge Problem, a puzzle posed by citizens of 18th-century Königsberg who wondered whether someone could walk through the city crossing each of its seven bridges exactly once. Mathematician Leonhard Euler proved in 1736 that it was impossible — and in doing so invented graph theory. TraceBlazer takes that same concept and turns it into a modern, interactive puzzle experience.

You can play TraceBlazer instantly in your browser on traceblazer.com with no download or installation required. It is also available as a native app on iOS and Android. Accounts sync seamlessly across all platforms so your progress follows you wherever you play.

The team at Samprino Tech wanted to create a puzzle game grounded in real mathematics — something that exercises genuine logical reasoning rather than just reflexes or memorisation. Graph theory felt like the perfect foundation: the puzzles have definitive right answers that players can discover through reasoning, not luck.

At the same time, we wanted the game to feel accessible and social. That is why TraceBlazer includes real-time multiplayer, daily challenges that everyone plays together, group tournaments, friend leaderboards, and a community puzzle editor.
