Play an online, multi-level, pirate-themed, match 3 puzzle game with a wide variety of level types on your mobile phone, tablet, notebook, laptop, or desktop PC! Pirates: The Match-3 is a challenging, multi-level matching grid puzzle game for kids, teens and treasure-loving adults where each level has a very specific task. Examples include levels where you must reach a specific points target, levels where you must eliminate a set number of colored gemstones, levels where you must clear blockades from the game grid, and many more! 

While your tasks change from level to level, the general "match three" gameplay remains the same; you must swap gems and other treasures around the grid in order to create matching groups of three or more adjacent pieces in a row either horizontally or vertically. Some levels are played against the clock, while in others, you are hindered by a limited number of moves!

This online, HTML5-based, match 3 brain teaser game has 50 levels, and should work on iOS and Android devices as well as most web browsers for PC / Mac. While a sense of urgency and sharp reactions are important for competing against the clock, good strategic planning and visual problem-solving skills are the key attributes required here. 

Cluttered game grids often require smart analytical thinking and creative engineering tweaks in order to create a solution where you can form matching groups more easily. Patience, high concentration, and a willingness for trial and error all come into play, especially in later levels when the grids are larger and more complex.  

Controls: Simply click or tap on the gemstone you want to move, and swipe to swap it with an adjacent gem. If this swapping move results in the creation of a matching group of 3 or more, great! If your swap is invalid (i.e. it doesn’t create a matching group), nothing happens until you go again.
