A new graph puzzle every day. Trace every edge exactly once without lifting your finger. Archive, practice mode, streaks, and haptics included. TRACE is a daily puzzle game built on a beautiful mathematical idea: draw every line in a graph exactly once, without lifting your finger. Each day, a new graph appears — the same puzzle for everyone. Drag from one of the two marked endpoints, connect node to node, and trace every edge. There's only one valid path through the graph. It's yours to find. DAILY PUZZLE A new graph drops every day at midnight. One puzzle, same for everyone. ARCHIVE Missed a day? Replay any of the last 30 puzzles at any time. PRACTICE MODE Sharpen your instincts with unlimited Easy, Normal, and Hard graphs whenever you like. STREAK & SHARE Track your daily streak and share your result with a single tap. NO ADS. NO ACCOUNTS. Just you and the graph. — The puzzle is rooted in Euler's theorem on graph traversal — the same insight that founded graph theory in 1736. The rules take seconds to learn. The depth takes longer to master.
