Spelling Dice

This game is designed for two players. Each player has a grid of 16 letters in a 4x4 grid (Qu is treated as a single letter). Both players have the same letters. The players are given a 3 minute time limit in which to use the letters for form words. The rules are that after the first letter the following letter must be next to the previous letter. To enter the completed word the player clicks the final letter twice. To undo a letter the player taps a previously selected letter.
Selected letters are shown with a different coloured background.
The game knows over 150,000 words, and so only words the game knows about are accepted.

When the time limit expires, the words entered are displayed, only words that are not common between the players score. Longer words score many more points.  
Words have to be at least three letters long to be entered.

The players may use the setting screen (click the cog icon), to change the player names or to stop the accepted words being displayed.
To end a game early, the players may click the play icon.

No internet access is required, so this may be played anywhere.
