VEXO: One Line Logic Puzzle

Can you draw it in one go? VEXO is a one line logic puzzle for people who like a proper brain teaser, and a live duel game for when you fancy beating someone else to the answer. How it works: trace one unbroken route that uses every line (edge) exactly once. A line can't be used twice, but you're allowed back through a dot. Tap dot to dot, draw with your finger, or leave it on Auto and play whichever way feels natural. Underneath sits a bit of classic maths, Euler's Seven Bridges of Königsberg problem, but all you need is a sharp eye and a plan. Solo campaign: 1,000 levels across 50 chapters • Gentle loops at the start, fiendish networks later, over 10 difficulty tiers • Every level is checked by the game to guarantee a solution exists • Chapter bonuses every 20 levels, then Endless mode beyond level 1,000 • Revisit any solved level from the Level Map and chase a faster time • Undo a move or start the puzzle again at any point When you're properly stuck • Hints: see a starting route, the next step or the whole solution • Credit Skip: spend Credits to jump to the next level • Ask a Friend for Help: share the exact level with a mate.
