Auto-complete
Enter two letters, and if the autocorrect feature for your device displays a related word it probably be the answer. If the answer you are looking for never appears in the first three slots, it is definitely not the correct word. By repeatedly doing this, you can easily check the answers get an advantage over your opponent. This also works in fast money rounds. If the word does not appear in the auto-complete, it is not one of the answers and you can quickly go back and delete it before you run out of time and enter a new guess.
