Old Clockmaker’s Riddle 

Old Clockmaker’s Riddle is a tile-matching game developed for Mac users. The app provides you with 50 challenging levels plus 25 mini-games, comes with a fascinating original storyline, has beautifully-drawn graphics and animations, and much more.

The storyline revolves on a small town where your objective is to get rid of the spells that were cast upon the houses. The only way to remove the curse is to complete various challenges consisting of Match 3 levels (the app features a help guide where you can learn how to play these games).

At the beginning of each level the app displays the amount of gems with clock hands you need to match; and once you reach the goal, the mission is complete. After you finish a challenge you receive a certain amount of colorful tokens which you can use to acquire power-ups (that break a number of gems, clear board, etc.).

Another good aspect is that the game offers you plenty of useful hints which you can use when you can spot a group of gems that can be matched.

To conclude, I'd say it's worth acquiring Old Clockmaker’s Riddle, especially if you're into playing Match 3 games. The app is filled with various challenges, provides you with plenty of power-ups, and comes with a fair cost.
