There's a rumour that every third Palm OS applicaiton is a full screen clock. Luckily Symbian seems to have avoided this curse, until now. There's yet another version of SuDoKu available for Series 60 now - Twisted Coding's SuDoKu Fun - with a set number of puzzles, the same user interface appearance (just some different colours). Come on guys, is it too much to ask for some innovation on the basic principle?
