Word Chain, an addicting word puzzler game

Change a letter to make a new word... then make a change again to make a chain!
Make new words by changing a letter in the current word. Using the mouse or keyboard, select the letter in the word you want to change, then click a letter on the pad to make a new word. Turn on all the lights to increase the score multiplier. Each word score the total of the letters plus time bonus multiplied by the multiplier. Remove the last word with the back button if you get stuck. The game is over if the time runs out. Later levels are made more tricky by less time bonus and disabled keys. UK or US dictionary can be selected by clicking "Options".
