I was just playing a Barcrest 'Grab The Bank' Emu and noticed that the Autonudge feature can waste your nudges when two wins are possible of the same amount.
Eg. while gambling nudges you see that you have a possible £1 win at 6 nudges and after gambling to 9 nudges also find that you have a possible £1 win. (On this machine A £1 win comes from either three apples or three £ signs). Any unused nudges can be saved, so you would have thought that the most logical Autonudge would use the 6 nudges, but Grab The Bank will use more nudges if the same prize can be gained from another nudge - wasting your 3 nudges!
I hadn't realised that this sort of Iffy programming went on - though I do know from experience that programming has many unintended consequences!
Anyone spotted other similar issues in other machines?
