Shameless plug - but I just built a word game based on an old children's game my family used to play on long car rides.

The game generates three words at random: light, blade, kill

The player has to type in a word that matches all three: switch

- light switch, switch-blade, and kill switch

As far as other word games, Cross With Friends is really good.
