Ultimate Puzzles Marine Life 2:

In Brief:
Ultimate Puzzles Marine Life 2 is a simple 16 square piece's jigsaw puzzle with five images and no lugs.

Introduction:
Ultimate Puzzles Marine Life 2 is a sequel to the puzzle collection that focuses on marine life, but now with an improved design and 16:9 aspect ratio. Choose the puzzle and put it forward. Each puzzle is 4x4 in size, but the complication is that the puzzles need to be rotated in the right direction.

The Game:
Ultimate Puzzles Marine Life 2 is another of those jigsaw puzzles from UniDen with square shaped puzzle pieces that have no lugs. We get five images to solve instead of the usual four. The theme is fauna in the sea. We've had several of these types of puzzle games previously from the developer UniDen, i.e. America, Japan, a couple of collections that combine previous puzzles give away i.e. Cars Collection and Puzzles Collection as well as a few other non jigsaw games such as Knight's Tetris, and Legend of the Fallen Castle 1 & 2.

Each of the puzzles is made up of 16 square pieces. which are placed on a 4 x 4 grid i.e. 16 pieces. Some of the pieces are not oriented correctly, so you will need to change their orientation by clicking on the piece with the left mouse button. Each click turns the piece clockwise 90 degrees. To place a piece on the board use the left mouse button, grab then move to the grid section you think it belongs on. If it is correct it will lock in place; if it's the wrong place it will move to a random place on the periphery of the jigsaws grid. The addition of rotating the pieces and also placing them in different places each time you attempt to complete the puzzle adds to the difficulty slightly. Also, some pieces will overlap at the start of each attempt and in some cases totally obscure one or more pieces. You can restart any of the puzzles at any time by clicking on the back arrow.

All the puzzles are relatively simple. An adult could easily complete the whole game in around 10 to 15 minutes at the very least. I think the developer is asking far too much over on Itch.io for a jigsaw with only five puzzle images and with only a small 4 x 4 grid at $5 per game. If all of the series were to be combined, it would seem a fairer price. That said, there are free jigsaw programs available online that in my opinion are far better than today's jigsaw puzzle; (okay it's free today).

The giveaway team gave away a jigsaw puzzle called Infinite Jigsaw Puzzle on Feb 13th 2008 which allowed your own images to be added to the game; plus, it had several jigsaw shapes from complex lugged shapes to various geometric shapes (though no squares) and you could adjust the difficulty from around 25 pieces to over a thousand. You could also create categories to place your image as well. I've still got that puzzle and sometimes dip into it, with several hundred images added over the years since I've had it. I'd buy it from the original developer if I could find them (Media Research Group); basically as a thank you for such a great jigsaw game that I received for free and have had many hours of enjoyment from it over the intervening thirteen years.

Notes on Security
I scanned a zipped copy of the installed game and it found zero hits from 58 antimalware engines. The downloaded executable may include some low level adware that only opens your browser to Falcoware's home page after the game has installed and places four shortcuts onto your desktop (which can be safely deleted once the game has installed). The installation does not inject any malware into your system. When your browser is opened to Falcoware's home page when the game has been installed, it earns Falcoware games some money, part of which is given to the developer of the game for allowing the game to be given away free.
