Puzzle #1Sort 16 words into 4 groups of 4 that share a theme.
See every puzzleWord Groups gives you sixteen words and asks you to sort them into four groups of four. Each group shares a theme, but the themes are hidden — finding them is the puzzle. There are fifteen puzzles and no signup, and each one takes two or three minutes.
Tap four words you think belong together, then submit. If they form one of the four hidden groups, the row locks in with its theme revealed. If not, it counts as a mistake.
You get four mistakes. Use all four and the puzzle ends and shows you the answers.
When a guess has exactly three of the four words right, you are told you were one away — which narrows the search rather than just telling you no.
Shuffle rearranges the tiles without costing anything. It is genuinely useful: a fresh arrangement breaks the accidental groupings your eye has started to see.
No, and deliberately so. There are fifteen puzzles per language and each visit walks them in a fresh random order, so you are not waiting on a clock and not replaying the same board.
Yes. Every puzzle has its own URL, and the archive lists all of them so you can pick one directly.
The format is the same idea, but the puzzles here are written for this site, and there is a full Vietnamese set — not a translation of the English one, but its own puzzles built around Vietnamese words.
