From the makers of 7 Little Words and Red Herring, Monkey Wrench is a word search puzzle where you've got to find the words among the hexagonal grid of letters. The monkey wrench in the process is that you don't get a list of words to find, you've got to figure that out yourself! You'll go bananas for this free iOS puzzle that's easy to learn, tricky to play, and hard to put down.
When Francis Bacon famously said that knowledge is power, he probably didn't mean that knowing trivia answers would grant you magical powers. But that's how things work in Quiz RPG: World of Mystic Wiz, a trivia game for Android that blends elements of roleplaying and card games. Control a group of five spirits in your various quests as an apprentice wizard, and turn your trivia answers into bolts of lightning or jets of water or fireballs. With over 15,000 questions in the pool, there's enough variety to last even the most hardcore of us quite a while. And there's a talking cat who mews if you poke her, so that alone makes it worth a look.
