Sixteen Malayalam tiles hide four groups of four — songs from one film, films by one director, dishes on a sadya leaf. Find all four in four mistakes. Some tiles look like they belong in two groups and only one arrangement works, which is the whole puzzle. A new one every day, the same for everybody.
Free, no sign-up, and nothing to install — it runs in the browser on one office network. Groups are built from Malayalam film credits and song data, then checked to have exactly one valid arrangement before a puzzle is ever served.
