This is a traditional match 3 based on a door that closes behind you and opens 7 portals, each will produce a key. There are nine game boards in each portal and you earn a puzzle piece with the completion of each board. At the end of the nine boards you assemble the puzzle pieces to complete the portal. The icons change with each portal. The down-side is that this swap game doesn't support 'drag and drop' technology, the movement of the icons is slow, and you can't make another move until the entire boards settles. The board configurations get more challenging and the power-ups become more plentiful. In portal 2 there are solid blocks in the board that you have to work around, and you can move any icon into the blank spaces created below them. This makes the game play a bit more strategic! The timer is just about right, but I did time-out in once in the first 22 boards I played during the 1 hour trial. There are 7 portals, some reading in between and a puzzle at the end of each portal. In 1 hour I completed 2 full portals and 4 of the 9 games in the third portal. With increasing difficultly this entire game can probably be played in 3-4 hours. It is relaxing and colorful, with a good soundtrack, and it follows the storyline. I'm interested to see where it goes!

some of it was a little hard, but fun.
