Betzillo

Betzillo is the Grand Tour: a calm, pure-logic puzzle about drawing a single closed loop that threads the centre of every station on a grid exactly once and returns to its start - a Hamiltonian cycle you build by hand. Tap the gap between two neighbouring stations to lay a link or lift it. Some links are given for free and locked in magenta; they pin every board to exactly one answer, so there is never guessing - only deduction. A finished loop gives each station two links, with no dead ends, no branches and no separate rings

Twenty loops rise in difficulty as the grid grows from four to eight stations a side and fewer links come pre-drawn, so the reasoning deepens step by step. Every puzzle is generated from a seed and proven to have a unique solution by a built-in solver, so what you see is always fair and always solvable. Finish quickly and lay no wrong links for three stars, bank coins, and spend them in the signal shop. No timers forcing mistakes, no pay-to-win - just one clean line, every station, and the quiet click of a loop closing
