The puzzles are challenging, but the rules are very easy: combine three gems that belong together.
Each combination includes a ‘head’ (example: D), a ‘tail’ (OG), and a ‘synonym’ (HOUND).
Example: D+OG = HOUND
There are 13 combinations hidden in each puzzle. Some gems belong to more than just one combination. Gems that are used up turn green.
