Had a ponder around yesterday, and think I've uncovered a 'Test site' as the machines seem to always be ones I've not seen before, and only tend to stay there for around 3-4 weeks.
Anyway, here's the ones that were there yesterday:
Red: Treasure Hunt
The 'top' logo looks very, very similar to that of the Global one with the same name. It's essentially a Snakez & Ladderz clone, with the only difference being that the bonus is of the 'gamble button' variety, like on Sub Zero, and such. It played well and I got a £35 top and a £25 red sevens about £8 after - which I collected, as I know how much SnL can 'arse about' getting you the top after hitting the £25. Walked away about £30 up.
Mazooma: Monkey Business
A clone of Monopoly / MMM, plays exactly the same. First board got me to £8, so past the £5 cutoff. It took £30 to offer 'Monkey Business' that went for £45. Nabbed a quick £6.70 'Go Bananas' (cashpot) about £2 later. Nothing really that exciting to speak of.
Mazooma: Gold Strike
Another clone of MMM, etc, but with at least one (that I spotted) subtle difference. There's no mystery on the bonus gamble, so you won't lose the first time that you hit it - but the one you hit is then unlit, and if you land on that one again, it's game over time. The £5 block was cracked after £20 in, and another £20 later and I managed to get the top, which went for £55. Next board was an 'all icon' affair, which went for £35.
So, nothing terribly new there, but I'll add more to this thread whenever they change, if they've not already been mentioned in detail on here...
