Dreams can be impossible to explain, but still make a strange kind of internal sense. So are the sentences you make in Sleep Furiously, a language game where the fun is in threading increasingly absurd sentences together, obeying grammar rules but few others.

"The results are really silly and can be totally absurd," Jen Helms of developer Playmation Studios tells me. "The name comes from the concept Noam Chomsky coined to demonstrate the linguistics concept our game explores: 'Colorless green ideas sleep furiously.'"

The game has a few modes: One in which you're challenged to get the highest score within a certain number of moves, and one where you chase the highest score within a time limit. There's also an "endless" one with no restrictions.

I really like this game—it's a playful expression of a linguistics concept that fans of word games will love. I actually think the developers can go a little bit further with it—because the boards randomize, increasing your scores tends to feel like it has as much to do with luck as skill. Sleep Furiously could learn a lot from Bookworm when it comes to how special tiles, multipliers and secondary goals can increase depth for the player.

But maybe the developer will be able to expand the game if this initial version is a success, and it's still a great, thoughtful way for word game fans to pass their time. You can get it on the App Store or on Google Play for $2.99. Read the rest
