Blockle

Each Blockle puzzle gives you a square grid and a set of pieces made of joined letter tiles, a bit like the shapes in a block-fitting game. Your job is to drop every piece into the grid so that each horizontal row spells a word. The pieces already face the right way, so there is no rotating; the challenge is working out which shape goes where and which letters end up next to each other.

The words in a puzzle share a theme, which is the main clue to what you are building. On some days the puzzle is tied to an occasion, such as International Pizza Day, Halloween or Christmas, with a greeting and a word list of its own. If you are stuck you can use hints to reveal the theme, the position or letter of an empty tile, or where the first piece goes, and you can give up to see the solution. The game counts your moves and time.

There are daily puzzles in English at 5x5, 6x6 and 7x7, and a mode built on Chinese four-character idioms. The day follows your local date, and your current and best streaks are kept in the browser, with a result you can copy or share. Blockle is free in the browser, has no ads and needs no account. It was made by Ollie Woodman, who started it in 2025 and publishes its code on GitHub, and can be played with a mouse, by touch or with the keyboard. It suits players who like spatial puzzles as much as word ones.
