What Is Unblock Me?

Unblock Me is Game CMB's original take on the classic sliding-block puzzle genre often called "Rush Hour" — a genre built entirely around one rule: every block moves in a straight line, and nothing else. The board is a 6x6 grid scattered with colored blocks of different lengths and orientations. One of them, the red block, needs to reach the exit on the edge of the board. Everything else is in its way.

That one rule is the entire game, and it's exactly why it works. A horizontal block can only slide left or right. A vertical block can only slide up or down. You can never lift a block over another, rotate it, or swap two blocks' places. Every level is really a small logic puzzle disguised as a physical one: figure out the order those blocks need to move in, and the exit opens on its own.

It runs entirely in the browser with no external art assets or licensed content — an original board, original blocks, original scoring system — and it drops you straight into a puzzle with a single tap. No install, no loading screen, no tutorial video to sit through first.

How to Play Unblock Me

1. Pick Classic for the full 64-level campaign, Time Attack for a 60-second sprint through as many puzzles as you can solve, or Daily Challenge for the one board every player worldwide gets that day.
2. Every block only slides along its own axis — drag a horizontal block left or right, a vertical block up or down (or tap a block, then use your arrow keys on desktop).
3. Move the other blocks out of the way to open a straight line from the red block to the exit on the edge of the board.
4. Slide the red block through the exit to clear the level. Fewer moves and a faster time both raise your score, and solving in the exact optimal move count earns a full 3 stars.
5. Stuck? Use Undo to walk back your last moves, Reset to start the level over, or spend one of your 3 free Hints to see a legal next move.
6. Clear levels back-to-back in Classic mode to build a streak bonus, then check the Leaderboard to see how your score stacks up globally or on that day's Daily Challenge.

Key Features

• 64 hand-verified levels running from a gentle tutorial board up through easy, medium, hard, and expert — every single one confirmed solvable by an actual breadth-first-search solver, so if a level feels impossible, it isn't: there's always a way through.
• A real single-axis sliding mechanic — horizontal blocks move left and right, vertical blocks move up and down, nothing rotates or jumps — the same core rule the entire genre is built on, with nothing dumbed down.
• Movement-lane highlighting — the row or column each block can slide along is tinted right on the board in that block's own color, so the sliding rule reads at a glance even before you touch anything.
• Three game modes: Classic for the full campaign, Time Attack for a 60-second puzzle sprint, and a Daily Challenge that puts every player on the exact same board once a day.
• A scoring system that rewards precision — your score is built from how close you get to the proven optimal move count and how fast you solve it, with up to 3 stars and a streak bonus for consecutive Classic clears.
• Undo, Reset, and 3 free Hints per session — Undo walks back one move at a time (up to 50 moves deep), Reset gives you a clean board, and Hints show you a legal next move without spoiling the whole solution.
• A server-verified leaderboard, split into Global and Daily views, with every score checked against your actual moves and solve time — no client-side score can fake its way to the top.
• No download, no account — a nickname is only needed if you want your score on the leaderboard, with light sound effects, haptic feedback on mobile, and one-tap score sharing built in.

Why Unblock Me Is So Addictive

Unblock Me works on a very old psychological hook dressed up in a modern package: a puzzle that looks solved is often one move away from a dead end, and a board that looks hopeless is usually one clever reorder away from opening right up. There's no timer forcing your hand, no random element deciding whether you win — every level is a fixed, fair, solvable arrangement, and the only thing standing between you and the exit is figuring out the right sequence. That makes "just one more level" an easy promise to make yourself, because the solution always feels like it's one insight away.

The scoring system turns that insight-chasing into something you keep coming back to improve. Solving a level at all feels good; solving it in the exact optimal move count for a full 3 stars feels completely different — and once you know a level can be solved that cleanly, going back and doing it slower feels unfinished. Layer in the Daily Challenge, where everyone on the leaderboard solved the literal same board you did, and a puzzle game suddenly has the same "did you beat my time" pull as a race.

5 Tips to Beat Your High Score

1. Don't move the first block you can — find the block you have to move. Random shuffling burns moves fast; look for the one block that's actually blocking your path before touching anything.
2. Work backward from the exit. Trace the red block's path to the edge first, then figure out which blocks sit in that path and where they need to go to clear it.
3. Some blocks need to move twice. A block that's out of the way now might need to move again later to let a different block pass — don't assume "solved" until the exit is actually clear.
4. Use a Hint before you burn ten moves guessing. A single Hint costs you nothing toward your final score compared to ten wasted moves — it's there to save your move count, not just your patience.
5. Play the Daily Challenge before checking the leaderboard. Everyone solves the exact same board that day, so your solve is a genuinely fair comparison — solve it fresh first, then see where you land.
