Nice, if you have the patience.
All Aces would be a nice game if played during a promotion where wagering on any game counted towards the score. Without the usual Autoplay though, tremendous patience and a medical risk of repetitive strain injury is the price.
As far as I know, Jackpot Factory still have All Aces within the general comp programme at the standard rate of 1 point per $10 played, thus a +EV of 0.01% on this alone. This is enough to make the game worth playing, even though ClearBonus has made an allowance for this with a measly 2% weighting. I expect the casinos are less worried about this than with Classic Blackjack due to the huge variance.
The problem with playing the other progressives when returns also reach +EV is that you could be spending the money to find some other player has beat you to the payoff that made the game worth playing. With All Aces, patience, and enough in the bank, you cannot lose in the long run until the casinos see enough players "at it" and change the rules to remove the +EV, which will most likely be by removing the comps. Classic BJ with comps provides a wafer thin house edge still, so this is less likely to change.
If All Aces came with autoplay, I doubt this opportunity would ever have existed.
A while ago, Jackpot Factory ran a wagering promotion that awarded $4000 to the top wagerer in the final week. Play on All Aces awarded a mere 1 point per $1500 wagered, but with the comps would have made it for the patient and persistent player with a big enough bankroll. The winner had in excess of 3000 points though, and this would have needed $4.5 Million wagered on All Aces, or 3.6 Million hands (at minimum bet) to be played manually in one week - I don't think the casino were worried about anyone managing this in order to cop an easy $4000 with little or no risk. The only way to beat this would have been to raise the bet to $25 per hand, and many MG casinos limit this to $10, and risk ruin before making the $4000
