hi ,what audi you still play in us dollars aswell ? cant see the point imho but each to there own , i could just understand, if your forced to play in dollars & can see the point your making about playtime because of exchange rate but i tend to stick to my sterling .
Not all MGS casinos offered UK Pounds as an option. When I joined Villento, I could NOT choose UK Pounds, so chose US$ as a default, rather than an even more "exotic" currency. Since many operators have pulled out of the US, it seems that UK Pounds have become available at those few MGS casinos that didn't initially offer it. This was probably down to the US making up over 90% of the player base before UIGEA, where a casino HAD to offer the currency of 90% of it's players, regarding the others as optional. RTG casinos STILL operate, for the most part, exclusively in US Dollars.
Play time can be extended by lowering the stake, as well as using a currency with a lower value. Some early slots however, limited the minimum coin to 25c, forcing low rollers to bet higher than they wanted to in UK Pounds, so this would have been an incentive to choose dollars. Later slots though, allow 1c coins, so it is easy to stake much less.
An illustration is the difference between the old slot "5 Reel Drive", a 9 line WEIGHTED video slot, with an effective minimum stake of 2.25 per spin due to 25c being the lower limit of selectable coin size, and the newer Thunderstruck, and UNweighted 9 line video slot with a 1c minimum coin, making it possible to play all lines on 9c, or 9p in UK Pounds, as against minima of £2.25 and $2.25 for "5 Reel Drive".
If you like bonus though, you are better off playing in UK Pounds, since bonus limits are defined in CREDITS, rather than absolute terms. So much is this advantage that most casinos will NOT permit non UK players to choose UK Pounds over their native currency (or the default of the US Dollar) in order to maximise their bonuses.
