You are presented with a constant stream of letter tiles, which you must quickly dispense with by forming words of 2 letters or more. A word's score is the sum of the values of the letter tiles (much like in Scrabble), multipled by a number of bonus factors. Earn these bonuses by submitting longer words (+0.5x for each letter above two), maintaining a streak of validly submitted words (+0.1x for each word in the streak), and clearing your queue (2x bonus). You must act quickly, though, for if the queue ever reaches nine tiles, a timer activates and the first tile in line starts turning red. If you don't submit a word in the few seconds before the timer runs out, that tile disappears, its point total is subtracted from your score, and worst of all, your streak bonus is reset!
Fans of leisurely, puzzle-like word games may find DeepLeap too fast-paced and may feel tempted to head directly to the Jumble. But before you go, give DeepLeap a shot! I myself normally choose stress-free puzzle modes whenever they are available, but I found this game remarkably addictive, and here are some of the reasons why:
It's accessible! Whether you have the vocabulary of a member of the Decemberists or that of a fifth-grader, you should be able to find words to submit without too much difficulty. You don't ever have to let the queue fill up — if you see a 3- or 4-letter word in the tiles that are already up, just go with it! Keep that ever-important streak going! Of course, it's better for your score if you're able to hold out for longer words, but it's not like you ever have to find a 9-letter monster. Also, DeepLeap doesn't make you feel inadequate if you didn't know that fragments like CEL and AWL are actual words.
It's balanced! DeepLeap is both offensive and defensive. Sure, it's great that you are able to submit SPHINX, but if it leaves you with EEO in your queue, then maybe you're better off playing something something like POXES and leaving HINE – giving you a much better chance of clearing your queue with your next word. It's designed never to give you more than 3 vowels or 4 consonants in a row, so with some care you can avoid ending up with draws like AIEUUUBAI. On the other hand, this is exactly where the 2-letter words come in handy as panic buttons.
It's fun! If the first two games that come to mind are arguably the world's most popular word board game (Scrabble) and the most popular word video game (Text Twist), you can probably assume that it's captured at least some of what's made those games so popular, which this definitely does.
It's addictive! The short but intense nature of DeepLeap combined with virtually unlimited replay value make it oh-so-easy to finish a game, take a deep breath, and then jump right back into the maelstrom. This is sometimes known as the "just one more game" syndrome.
Now, that's not to say that DeepLeap isn't without its problems, and since John Resig currently presents it as a demo, I feel no hesitation in pointing them out for the greater good of the finished product: First of all, the letter values are definitely out of proportion, meaning that not only are words containing Q, X, or J pretty much guaranteed to be worth as much as most words twice their size, but if one of these letters shows up in your queue, you'd better do your darnedest to get rid of it, or pay a stiff penalty!
Secondly, the timer needs to be more visible, especially when your queue is full and you're trying frantically to find a word while simultaneously attempting to discern the subtle differences between crimson, cherry, and carmine.
Lastly, the tile timer could stand to be a little slower as the queue fills up; after all, the possibilities for forming words are increasing exponentially, so it would make sense to give the player more time to process the new letters.
Although DeepLeap is currently just a demo, I see very few other flaws. Part of the greatness of the game lies in its simplicity, and I don't see that adding new gameplay features like powered tiles could really improve it. Music, sound effects, and eye-pleasing graphics would certainly add a bit of polish, but that would just be the rainbow sprinkles on top of an already-delicious ice cream sundae.
