Gridlock — Unblock the Red Car

A red car stuck in a 6×6 parking lot. Slide the other vehicles to open a way out. 240 puzzles whose minimum move count is proven, not guessed. Every vehicle moves along its own axis only — never sideways. The exit is on the right edge of the board, on the red car's row. A logic and brain puzzle game you understand in ten seconds, play with one thumb, and run entirely offline. THE OPTIMAL MOVE COUNT IS PROVEN Every one of the 240 levels has been run through a solver: its minimum move count is not estimated, it is computed by an exhaustive search, then re-checked by automated tests. When the screen says "Moves: 12 · optimal 9", that 9 is a fact. The stars are built on it: 3 stars for the exact optimum, 2 for up to three moves over, 1 for escaping the jam no matter what it took. You always know whether a level can be played better — and by how much. A DIFFICULTY CURVE THAT ACTUALLY CLIMBS Four packs of 60 levels, ranked by their proven minimum: • BEGINNER — 6 to 10 moves: learn the motion, learn to read the board. • ADVANCED — 11 to 18 moves: the first counter-intuitive detours. • EXPERT — 19 to 28 moves: you will have to undo in order to redo. • NIGHTMARE — 29 to 49 moves: long maneuvers where every vehicle moves more than once. Within each pack, levels are sorted by increasing optimum: the next step up is always a little higher, never a wall. A DAILY CHALLENGE, EVERY DAY A new level every day, drawn for today's date among the ones you have not solved yet. It does not change until tomorrow. Solving it keeps alive your streak of consecutive days, shown on the home screen. Nothing to claim, no reward that expires, no notification: just a reason to come back. A HINT THAT THINKS, NOT A RECORDED SOLUTION Stuck? The hint recomputes the optimal path from your current position — not from the start, not from a stored solution — and shows you the next move: a ghost vehicle and an arrow, the rest is up to you. Even ten wasted moves in, it picks up from where you actually are. Using one forfeits the level's perfection star. One hint is free every day; beyond that, hint packs are available as an in-app purchase. MADE FOR PLAYING IN PEACE • No lives, no energy, no timer: a puzzle can be put down and picked back up — it cannot be "failed". • Unlimited undo, one-tap restart, and the game in progress resumes exactly where it was, even after closing the app. • The optimal count display can be switched off in the settings, for those who prefer searching without a reference. • One gesture: a vehicle slides along its axis and snaps to the grid. Vibration can be turned off. • Dark or light theme, carefully tuned contrast; vehicles are told apart by shape and position, not just color. SIMPLE AND HONEST • Works entirely offline, from the first move to the last. • No ads, no videos to sit through. • No account, no sign-up: your progress stays on your phone and nowhere else. • The first 40 levels are included. A one-time purchase, no subscription, unlocks all 240 for good, and can be restored after switching phones. Hint packs are optional. A sliding block puzzle, a parking lot to untangle, a jam of cars to clear: this car puzzle game plays standing on the train or lying in bed, with no wifi and no mobile data. What is different here: a real difficulty curve, from 6 to 49 moves, an exact optimal on every one of the 240 boards, and a fresh challenge every day. The exit is on the right. The route is up to you.
