For those of us who remember 3-2-1 from the 1970s and 80s, this catches most aspects of the show. We have the question round to start with, though this is more in the style that the first to know the answer shouts it out, rather than 30 seconds each.
Then there is a silly round where you have to put a bag of rubbish into Dusty Bin several times over.
As with the gameshow, there are in the final round, acts (probably taken from actual shows broadcast on TV), with a clue and rhyme following each one. On must read the clue for oneself, and does not get enough time to do so. Further, when a prize is reveal, there is not explanation of how the clue referred to the prize, as Ted Rodgers used to give.
Therefore I don't feel the experience is complete!
