Here's a word game I wrote, it should work great on the kindle fire, its called Word Jumble.

Amazon.com: Word Jumble: Appstore for Android

Very simple interface, making entering letters a breeze.

Install it and give it a test drive...I suggest using easy level to start with...I made medium and hard 2-3 times harder by using real spelling bee words.

Hope you enjoy.
