The blocks which fall into the screen is actually an alphabet. Each block will have an alphabet mentioned on it. You need to place the alphabets suitably to make words. Words can be horizontal, vertical and may be diagonal as well. We will obviously know which block (alphabet) will come next so we plan ahead suitably.
There are additional features like a special block which lets you swap any 2 alphabets. Many more such features can be added to let the user score more and learn words and spellings and improve vocab. So needless to say it would be a nice app for kids and adults too!-- ravi kris334, Jul 26 2014 This idea would make more sense if the word "alphabet" was replaced with 'letter" (or, possibly, "phonetic syllable").-- Vernon, Jul 26 2014 random, halfbakery
