Try the guessing game with a short sentence of 4–6 words. The letters must be guessed in
the correct order, from first to last. Get someone to write down the letters as they are
found and keep a record of how many guesses it takes to find each letter. Any questions
with a yes/no answer can be used. Examples would be, “It it a t?” “Is it a vowel?” “Does
it come before m in the alphabet?” A space between words also counts as a “letter” and
must be guessed. Take turns and see if you can discover which parts of messages are
easiest to find out.
