For this you will need to prepare a list of 5 syllable words (pick common words people would know) broken into syllables to make it easier for yourself. You can find lists online. You will read each word out 1 syllable at a time and players will buzz in when they think they know what the word is going to be. If they buzz in with an incorrect guess, they are frozen out for the remainder of that word.

Scoring is, as always, completely arbitrary, but I have usually awarded points based on how quickly they have guessed (e.g., 4 points if they guess after the first syllable, 3 after the second, etc.). Decide how you wish based on the number of players.

I just have players shout their names as the buzzer, but you could some sort of noisemaker for each or have a bell or horn in the middle tehy can make a grab for.

You can freeze people out for just guessing after the next syllable if you don't want to eliminate people from guessing completely.

You can do 4 syllable words if you have younger players.
