Bonus Tile: On
Time Attack: On
Word Find: On
Banned Letter: Off
Time attack adds 2 seconds to the clock for every word you find and Word Find gives you an alphabetical list on the left hand side of the screen. So long as you find the words in that order the list will scroll so you won't get stuck trying to find some obscure/arcane word.
There are solvers online that will put the list in an easier to solve order (For example http://boggle.wineverygame.com/boggle/helper.pl
)but then you lose time typing them in and looking back and forth.
Additionally solvers ALWAYS contain words the games do not and quite frequently word games will include words that the solvers will not.
