Bundlemere

Bundlemere is a word-grouping puzzle at a riverside market. Sixteen words hide four bundles of four that share a theme, such as birds, rivers or workshop tools. Pick four and tie them: a right bundle becomes a ribbon with its theme, a wrong one costs one of four spools of string, and the game tells you when you were one word away. A peek names one word's theme for a spool. Forty puzzles go from three bundles of distant themes to four bundles with look-alike themes side by side, plus a harder daily puzzle; every puzzle is checked so that no shown word belongs to two of its themes. It plays in the browser with a keyboard, mouse or touch, in English or Bulgarian.
