For those who are fond of word games that are fast-paced and challenging, there is the cross-platform multi-player Ruzzle. As someone who grew up playing Boggle and Text Twist, this was a no brainer to try. While it may be an Android port, there is nothing like a simple word game for keeping the noggin in shape all while taking on friends and strangers.
The goal here is to form as many words as you can on the small rectangular grid in two minutes against an online opponent. Words can be as small as two letters and you must use letters that are adjacent to each other. There are three rounds played and the one with the highest score wins. Points are awarded based on word length, bonus pieces, and letter scores. What I do like is how at the end of each match it displays all of the possible combinations. Not only does this improve your vocabulary but aids in retention for other games, at least for me. It also offers the ability to chat with opponents, play against your Facebook friends, or challenge a random stranger.
Game play is smooth and as you can see in the video above, there was no evidence of it being slow or not responding to my touch especially since I updated to OS 10.1. I find it to be quite enjoyable but I'm a sucker for word games especially when under pressure of a ticking clock. The only thing I did notice was how when finding an opponent it did seem to slow down a bit but I attribute it to network connectivity. Also, notifications do not work in the hub but you can always refresh the main screen to update the game in progress.
I would like to see this as a native application and the ability to run without an internet connection so that practice play would work offline. Unfortunately, the game will set you back $2.99 as the free version found in the Google Play store is not available. If you are comfortable with Android Ports and love word games then this is one you will enjoy with the quirks that go with it.
