Trail — Daily Hamiltonian Path Brain Game
Trail is a free daily logic puzzle. Each grid hides one path that starts at 1, visits every empty cell exactly once, and reaches the last number through 2, 3, 4 … in numerical order. Practice with endless generated puzzles or come back every day for a curated challenge with streaks and a weekly bonus board.
