A word game like Tetris, free in your browser
Word Stack in the Letternerd Arcade is a word game in the spirit of Tetris, though not a copy: single letter tiles drop into columns, not falling block shapes. Slide each tile left or right and drop it, and when a word lines up across a row it bursts and the tiles above fall. Fill a column to the top and the run ends. It is free in any browser.
What is Tetris?
Tetris is the falling-block puzzle created by Alexey Pajitnov in 1984. Shapes made of four squares fall into a well; you move and rotate them so they fit together, and every complete line clears. As the speed rises the stack climbs, and the game ends when the pieces reach the top. It has appeared on almost every console, computer and phone since.

| Moving pieces | Move and rotate each shape | Slide left or right and drop; nothing to rotate |
| What clears | A complete line | A word of 3 to 7 letters lined up along a row |
| Chains | Clearing several lines at once scores more | A burst can drop tiles into new words, and each step of the chain scores more |
| Looking ahead | The next piece is shown | The next letter is shown |
| Ending | The stack reaches the top | A column fills to the top, or the clock runs out |
| Comparing | Depends on the version | A daily board, with a friends view |
