2048 Unblocked: One Weekend, Four Million Players, Zero Dollars
Gabriele Cirulli was 19 years old and built 2048 Unblocked over a single weekend in March 2014. He published it on GitHub as open-source with no plans beyond seeing if people liked it. Four million visitors arrived within the first week. The Wall Street Journal called it "almost like Candy Crush for math geeks." Came back four sessions testing this page. The grid is small. The decisions compound fast. That's the entire problem.
Slide, Merge, Repeat
You start with two tiles on a 4x4 grid, each showing either a 2 or a 4. Every move slides all tiles in one direction as far as they can go. Two tiles with the same number that collide merge into one with double the value. 2+2 becomes 4. 4+4 becomes 8. Keep merging until you hit 2048. After every move, a new 2 or 4 tile appears randomly in an empty space. The game ends when no moves remain. Getting to 2048 is the goal. Going beyond it is the real challenge.
Why This Is Harder Than It Looks
The problem is board management. Every move affects every tile simultaneously. A move that merges two tiles in one corner might also scatter tiles you needed somewhere else. The grid fills up faster than expected. By the time you have a 256 tile, the board is already crowded and the margin for error shrinks. Most first-time players hit a wall around 512. Getting to 1024 requires actually thinking two or three moves ahead. 2048 requires a strategy held consistently across the whole game.

The Corner Strategy That Actually Works
- Pick a corner, stay there: Keep your highest tile in one corner the entire game. Every move should work toward keeping that corner occupied by your biggest number. Switching corners mid-game is how most runs fall apart.
- Fill one row completely: Keep the row adjacent to your corner full. This lets you move tiles along that row freely without the high tile drifting toward the center.
- Only two directions to start: If your high tile is in the bottom-left, only slide left and down. Never slide up or right unless you have absolutely no other option. Every exception costs you position.
- Don't chase small tiles: Resist merging small tiles in the middle of the board when your high tiles need specific positioning. Merging a 4+4 in the center might block the path your 256 tile needs.
- Build in order: Try to arrange tiles in descending order along the corner row: 1024, 512, 256, 128. This creates a natural merge chain when the right tiles arrive.
One Weekend Project That Changed Puzzle Gaming
2048 was created by Gabriele Cirulli, an Italian web developer, and published March 9, 2014. He described it as an improved clone of the game 1024 by Veewo Studios, which itself was inspired by Threes. Cirulli released the source code under the MIT License, which led to hundreds of variants and clones appearing within weeks. The game runs in any browser using JavaScript and CSS. No plugins, no installs. The version here loads in under two seconds.
