Hell's Bells
This is a Caveman Capers clone where the only main differences seem to be that (a) there is a 'following wind' factor that varies with each shot and which seems to push the maximum shot up into the c. 230 points territory and (b) the prizes seem further away by default - it was 2000 for £1 and 10,000 for £20. The pub in question was one which I'd be surprised to find any decent players frequenting (it's in rural Oxfordshire) and as the game must have been pretty new, it seems that, unlike Caveman Capers, this one has been designed not to start in paying mode but it could well be a decent find if you catch it right.
Top of the Pops
I was amazed to see this. Despite a really ropey colour scheme/look and feel it is basically Top of the Pops 2 with a new question set, and hence it is definitely good news if this one gets a general release. The only slight quirk seems to be that it has a lot more 'NOT' questions in the set, e.g. "Which of these musicians was NOT ever in Blondie?" which is fine unless you play it straight after Every Loser Wins, in which case it really addles your brain!
Crossword Quiz
I didn't get a chance to play this but it should definitely be worth a look - I'm assuming it isn't just a rebrand of Quids for Grids.
In general, the new games all seem more promising than the vast proportion of recent releases.
