New Tool in School

I've developed a new tool that presents the user with 9 letter tiles on screen. Any list of words (8 letters or less, preferably 7 or less) can be used.

On startup the program will choose 9 tiles offering the user as least 10-15 possible words hidden within. When the user finds a word the program will replace ONLY the used tiles and will replace them in such a way as to maintain around 10 possible words hidden within. 

The first version of the game is already on the site and contains a list of animals. There are around 245 animals in the list and the list is all the program requires. It can even work with as little as 35 words in the original list.

In the current version there are 4 360° backdrops featuring the four seasons and some ambient animal sounds. Even so, the game is around 10 megabytes.

With a simple change of the backdrop and word list we would have a completely new game.

I am working on improving the algorithm and extending it to 4*3 and 4*4 tiles to allow for longer words in the near future. However as this version was aimed at the younger kiddies I kept it as simple as possible. 

In school the results so far have been positive with the kids playing in small groups with little or no prodding or instruction.

Here you can see 'under the hood'. The possible answers are listed on the left.
